Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ssmtp-2.65/COPYRIGHT000066400000000000000000000013661506500640000141110ustar00rootroot00000000000000sSMTP is licensed under the GNU General Public License (GPL) version 2 or above.

Then type: make and finally install the files: make install or to install it as the main Mail Transport Agent make install-sendmail -- Hugo Fedora Core 1 system install: ----------------------------- I would actually just suggest the INSTALL from automake. But: If you are building sSMPT from scratch the following steps worked on a Fedora Core 1 system. To install it in the /usr/local directory: ./configure make make install Then edit the ssmpt.conf file /usr/local/etc and create a symbolic link from where your system thinks the sendmail binary goes to the /usr/local/sbin/ssmpt executable. -- Sven Heinicke Information about the options: ------------------------------ To install this program, you compile it with the correct options and copy the binary. If you have more than one community which uses a given binary, there is a small (3 line) config file that allows setting variables that aren't static. These three are root: The person who gets root's mail (also daemons', etc). This userid (on the mailhub) get all mail sent to local adressees with userids less than 10. In other words, she gets mail the system mails to root, daemon, etc. mailhub: The place where the mail goes. This is looked up with gethostbyname, and so must resolve to an IP address. MX records don't count, as several vendors' machines that we run ssmtp on (notably suns) don't fully support them. They'd be nice, though... rewriteDomain: The place to say the mail came from. This is for hostname-hiding, and only applies if the programs is compiled with REWRITE_DOMAIN defined. We don't usually have to do so (our main mailhubs run zmailer: our clients run all sorts of junk). hostname: the Fully Qualified Domain Name of the machine, in case you have set hostname to the short form. The full set of options are discussed in the makefile, and briefly are the type of machine to compile for, the place to send the mail and the domain to rewrite to, if applicable. To make multiple versions I use symlink-trees and scripts that passes options to the make command, then renames the binaries to things like ssmtp.S4C-SunOS4.1.1... I also can make DEC-style setld kits. -- dave ssmtp-2.65/Makefile.in000066400000000000000000000037121506500640000146600ustar00rootroot00000000000000 srcdir= @srcdir@ prefix=@prefix@ exec_prefix=@exec_prefix@ libexecdir=@libexecdir@ bindir=$(prefix)/sbin mandir=$(prefix)/man/man8 LN_S=@LN_S@ CC=@CC@ etcdir=@sysconfdir@ SSMTPCONFDIR=$(etcdir)/ssmtp # (End of relocation section) # Configuration files CONFIGURATION_FILE=$(SSMTPCONFDIR)/ssmtp.conf REVALIASES_FILE=$(SSMTPCONFDIR)/revaliases INSTALLED_CONFIGURATION_FILE=$(CONFIGURATION_FILE) INSTALLED_REVALIASES_FILE=$(REVALIASES_FILE) # Programs GEN_CONFIG=$(srcdir)/generate_config SRCS=ssmtp.c arpadate.c base64.c xgethostname.c @SRCS@ OBJS=$(SRCS:.c=.o) INSTALL=@INSTALL@ EXTRADEFS=\ -DSSMTPCONFDIR=\"$(SSMTPCONFDIR)\" \ -DCONFIGURATION_FILE=\"$(CONFIGURATION_FILE)\" \ -DREVALIASES_FILE=\"$(REVALIASES_FILE)\" \ CFLAGS=@DEFS@ $(EXTRADEFS) @CFLAGS@ .PHONY: all all: ssmtp %.dvi: %.tex latex $< .PHONY: install install: ssmtp $(GEN_CONFIG) $(INSTALL) -d -m 755 $(bindir) $(INSTALL) -s -m 755 ssmtp $(bindir)/ssmtp $(INSTALL) -d -m 755 $(mandir) $(INSTALL) -m 644 $(srcdir)/ssmtp.8 $(mandir)/ssmtp.8 $(INSTALL) -d -m 755 $(SSMTPCONFDIR) $(INSTALL) -m 644 $(srcdir)/revaliases $(INSTALLED_REVALIASES_FILE) $(GEN_CONFIG) $(INSTALLED_CONFIGURATION_FILE) .PHONY: install-sendmail install-sendmail: install $(RM) $(bindir)/sendmail $(LN_S) ssmtp $(bindir)/sendmail $(INSTALL) -d -m 755 $(libexecdir) $(RM) $(libexecdir)/sendmail $(LN_S) sendmail /lib/sendmail $(RM) $(mandir)/sendmail.8 $(LN_S) ssmtp.8 $(mandir)/sendmail.8 .PHONY: uninstall uninstall: $(RM) $(bindir)/ssmtp $(RM) $(mandir)/ssmtp.8 $(RM) $(CONFIGURATION_FILE) $(REVALIASES_FILE) $(RM) -r $(SSMTPCONFDIR) .PHONY: uninstall-sendmail uninstall-sendmail: uninstall $(RM) $(bindir)/sendmail /lib/sendmail $(RM) $(mandir)/sendmail.8 # Binaries: ssmtp: $(OBJS) $(CC) -o ssmtp $(OBJS) @LIBS@ $(CFLAGS) $(LDFLAGS) .PHONY: clean clean: $(RM) ssmtp *.o md5auth/*.o core .PHONY: distclean distclean: clean docclean $(RM) config.* Makefile .PHONY: docclean docclean: $(RM) *.dvi *.log *.aux ssmtp-2.65/README000066400000000000000000000045351506500640000134770ustar00rootroot00000000000000Purpose and value: This is sSMTP, a program that replaces sendmail on workstations that should send their mail via the departmental mailhub from which they pick up their mail (via pop, imap, rsmtp, pop_fetch, NFS... or the like). This program accepts mail and sends it to the mailhub, optionally replacing the domain in the From: line with a different one. WARNING: the above is all it does. It does not receive mail, expand aliases or manage a queue. That belongs on a mailhub with a system administrator. The man page (ssmtp.8) and the program logic manual (ssmtp_plm) discuss the limitations in more detail. It uses a minimum of external configuration information, and so can be installed by copying the (right!) binary and an optional four-line config file to a given machine. Type of systems supported: Berkeley-derived, or ones otherwise using /usr/lib/sendmail as a mail transfer agent. In use on SunOS 4.1.1, NextStep 2.x/3 and Ultrix 4.2, tested briefly on AIX 3.2 and RISCos. Tested by others on DG U/X 5 and SVR4. You may need to #define USE_OLD_ARPADATE for the Cygwin port of ssmtp (otherwise the day of the month would always be the letter "d"). Dependencies: External: Berkeley sockets and supporting libraries. Known limitations: This is not a complete sendmail. It is only a program to post mail to a mailhub for people who don't *want* a complete sendmail. Therefore a lot of flags are not supported. The old header limit of 4K is fixed and the number of recipients is as large as can be held in memory. Known problems: Pine uses a lot of sophisticated options to talk to sendmail, and uses batched SMTP input which is not supported. The solution is to use your mailhub as smtpserver in pine.conf. If the mailhub is not reachable, sSMTP will fail.

It also supports authentication with RSA keys, to enable you to (if you patch the MTA on the mailhub) have RSA key checks on all relay mails. He wanted this so that he could have the same SMTP server on his laptop even when he moved around on different networks. As he said - "I could have used postfix as I did on my mailhub, but that was overkill, so I patched the smallest program there was :)" information about smtp over ssl for postfix is avalible at: http://www.aet.tu-cottbus.de/personen/jaenicke/pfixtls How to use this: I had to add the following config directives: UseTLS=YES/NO Set this to yes and ssmtp will try to connect with SSL to the remote machine. UseSTARTTLS=YES/NO Do a EHLO/STARTTLS before starting the SSL negotiation (see http://www.ietf.org/rfc/rfc2487.txt). UseTLSCert=YES/NO Set this to yes to make ssmtp identify itself with a certificate. TLSCert= Specify which certificate file should be used. TODO: * Check server certificate for changes and notify about it. * Diffrent Certificate and Key file? ssmtp-2.65/arpadate.c000066400000000000000000000053761506500640000145500ustar00rootroot00000000000000/* * arpadate.c - get_arpadate() is a function returning the date in the * ARPANET format (see RFC822 and RFC1123) * Copyright (C) 1998 Hugo Haas * * Inspired by smail source code by Ronald S.

" ]" .br .B /usr/lib/sendmail .RI "[ " flags " ] [ " address " " ... " ]" .br .SH DESCRIPTION .I ssmtp is a send-only sendmail emulator for machines which normally pick their mail up from a centralized mailhub (via pop, imap, nfs mounts or other means). It provides the functionality required for humans and programs to send mail via the standard or /usr/bin/mail user agents. .PP It accepts a mail stream on standard input with recipients specified on the command line and synchronously forwards the message to the mail transfer agent of a mailhub for the mailhub MTA to process. Failed messages are placed in dead.letter in the sender's home directory. .PP Config files allow one to specify the address to receive mail from root, daemon, etc.; a default mailhub; a default domain to be used in From: lines; and per-user From: addresses and mailhub names. .sp .PP It does not attempt to provide all the functionality of sendmail: it is intended for use where other programs are the primary means of at last mail delivery. It is useful with pop/imap, or to simulate the Sun shared mail spool option for non-Sun machines, for machines whose sendmails are too difficult (or various) to configure, for machines with known disfeatures in their sendmails or for ones where there are ``mysterious problems''. .PP It does not do aliasing, which must be done either in the user agent or on the mailhub. Nor does it honor .forwards, which have to be done on the receiving host. It especially does not deliver to pipelines. .SH OPTIONS Most sendmail options are irrelevant to sSMTP. Those marked ``ignored'' or ``default'' have no effect on mail transfer. Those marked ``unsupported'' are fatal errors. Those marked ``simulated'' are not errors, but the result is for the program to exit with an informative message. A sort of fatal non-error. .TP .B \-4 Forces ssmtp to use IPv4 addresses only. .TP .B \-6 Forces ssmtp to use IPv6 addresses only. .TP \fB\-au\fP\fIusername\fP Specifies username for SMTP authentication. .TP \fB\-ap\fP\fIpassword\fP Specifies password for SMTP authentication. .TP \fB\-am\fP\fImechanism\fP Specifies mechanism for SMTP authentication. (Only LOGIN and CRAM-MD5) .TP .B \-ba (unsupported) ARPANET mode. All input lines must end with a LINEFEED, and all messages will be generated with a CR-LF at the end. Also, the ``From:'' and ``Sender:'' fields are examined for the name of the sender. .TP .B \-bd (unsupported) Run as a daemon. .TP .B \-bi (ignored) Initialise the alias database. .TP .B \-bm (default) Deliver mail in the usual way. .TP .B \-bp (simulated) Print a summary of the mail queue. .TP .B \-bs (unsupported) Read SMTP commands from stdin. .TP .B \-bt (unsupported) Run in address test mode. .TP .B \-bv (unsupported) Verify names only. .TP .B \-bz (unsupported) Create the configuration freeze file. .TP \fB\-C\fP\fIfile\fP Use alternate configuration file. .TP \fB\-d\fP\fIX\fP Set debugging value to X. .TP .B \-E (ignored) Don't trust userid of sender. .TP \fB\-F\fP\fIfullname\fP Set the full name of the sender. .TP \fB\-f\fP\fIname\fP Sets the name of the ``from'' person. This option is valid only if no From: line is specified within the header of the email. .TP \fB\-h\fP\fIN\fP (ignored) Set the hop count to N. .TP .B \-m (ignored) Ignore originator in alias. .TP \fB\-M\fP\fIid\fP (ignored) Attempt to deliver the queued message with message-id id. .TP \fB\-N\fP \fIdsn\fP (ignored) Set delivery status notification conditions to dsn. .TP .B \-n (default) Do not do aliasing. .TP \fB\-oA\fP\fIfile\fP (ignored) Use alternate alias file. .TP .B \-oc (ignored) Delay ``expensive'' connections. .TP \fB\-od\fP\fIx\fP (ignored) Set the delivery mode to interactive/synchronous, background or queue (Always interactive). .TP .B \-oD (ignored) Run newaliases if required. .TP \fB\-oe\fP\fIx\fP (ignored) Set error processing to mail, write, print or quit. (Always print). .TP \fB\-oF\fP\fImode\fP (ignored) The mode to use when creating temporary files. .TP .B \-of (ignored) Save UNIX-system-style ``From'' lines at the front of messages. .TP \fB\-og\fP\fIN\fP (ignored) Set group ID to use when calling mailers. .TP \fB\-oH\fP\fIfile\fP (ignored) Set SMTP help file. .TP .B \-oi (default) Do not take dots on a line by themselves as a message terminator. .TP \fB\-oL\fP\fIn\fP (ignored) The log level. .TP .B \-om (default) Send to ``me'' (the sender) also if in an alias. .TP .B \-oo (unsupported) If set, this message may have old style headers. .TP \fB\-oQ\fP\fIqueuedir\fP (ignored) Select the directory in which to queue messages. .TP \fB\-or\fP\fItimeout\fP (ignored) The timeout on reads. .TP \fB\-oS\fP\fIfile\fP (ignored) Save statistics in the named file. .TP .B \-os (ignored) Always instantiate the queue. .TP \fB\-oT\fP\fItime\fP (ignored) Set timeout on messages. .TP \fB\-ot\fP\fIstz,dtz\fP (ignored) Set the name of the time zone. .TP \fB\-ou\fP\fIN\fP (ignored) Set the default user id for mailers. .TP \fB\-q\fP\fI[time]\fP (simulated) Process the queue. .TP \fB\-r\fP\fIname\fP Same as -f. .TP \fB\-R\fP\fIstring\fP (ignored) Process queue for recipient. .TP \fB\-R\fP \fIreturn\fP (ignored) Set the amount of the message to be returned if the message bounces. .TP .B \-t Read message, searching for recipients. ``To:'', `Cc:'', and ``Bcc:'' lines will be scanned for people to send to. Any addresses in the argument list will be suppressed (not supported). .TP .B \-v Go into verbose mode. .TP .B \-V Say version and quit. .SH REVERSE ALIASES A reverse alias gives the From: address placed on a user's outgoing messages and (optionally) the mailhub these messages will be sent through. Example: .sp .RS +.3i .ta 1.0i .nf root:jdoe@isp.com:mail.isp.com .fi .RE .sp Messages root sends will be identified as from jdoe@isp.com and sent through mail.isp.com. .SH FILES /etc/ssmtp/ssmtp.conf - configuration file .br /etc/ssmtp/revaliases - reverse aliases file .SH SEE ALSO RFC821, RFC822, ssmtp.conf(5). .SH AUTHORS Matt Ryan (mryan@debian.org) Hugo Haas (hugo@debian.org) Christoph Lameter (clameter@debian.org) Dave Collier-Brown (davecb@hobbes.ss.org) .SH BUGS sSMTP does not support exception lists to the -t option (never seen it used). sSMTP will fail if the mailhub is unreachable. ssmtp-2.65/ssmtp.c000066400000000000000000001257161506500640000141360ustar00rootroot00000000000000/* sSMTP -- send messages via SMTP to a mailhub for local delivery or forwarding.

It contains no suid-binaries or other dangerous things - no mail spool to poke around in, and no daemons running in the background. Mail is simply forwarded to the configured mailhost. Extremely easy configuration. WARNING: the above is all it does; it does not receive mail, expand aliases or manage a queue. That belongs on a mail hub with a system administrator. %prep %setup export PATCH_GET=0 %patch -p1 %build %configure %{configopt} %{__make} %install %{__rm} -rf %{buildroot} %{__make} INSTALL_PREFIX="%{buildroot}" install %post %{_sbindir}/ssmtp_generate_config %{_sysconfdir}/ssmtp/ssmtp.conf %postun %clean %{__rm} -rf %{buildroot} %files %defattr(-,root,root) %doc COPYING INSTALL README TLS %config(noreplace) %{_sysconfdir}/ssmtp/* %{_sbindir}/* %{_mandir}/man?/* ssmtp-2.65/xgethostname.c000066400000000000000000000053471506500640000154730ustar00rootroot00000000000000/* Copyright (c) 2001 Neal H Walfield .
