INSTALL

+To install ssmtp:
+-----------------
+
+Check the options and directories in Makfile.
+
+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 <sven@nec-labs.com>
+
+
+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.

README

+Purpose 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.

TLS

@@ -0,0 +1,34 @@
+Tobias Rundstrom supplied a patch to ssmtp to enable secure mailtransfer
+between your local (ssmtp) machine and the mailhub. 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=<file>
+Specify which certificate file should be used.
+
+
+TODO:
+* Check server certificate for changes and notify about it.
+* Diffrent Certificate and Key file?
+
+
