Yeah, it's pretty easy.
I strongly suggest running SA with SPAMD and SPAMC.
SPAMD will always run, and when postfix receives an email it will spawn a
filter script which in turn execs SPAMC process which is written in compiled
C and very lean/small footprint. Otherwise, it will be spawning a new PERL
process for each instance of SA and that is SLOW and bloated.
So you start SPAMD: (replace 0.0.0.0 with IP of your box. I don't want spamd
talking to any other boxes!)
spamd --daemonize -p 783 --pidfile
/var/run/spamd.pid -x --allowed-ips=127.0.0.1,0.0.0.0
You might want to create a nice rc.d init script, or just tack this onto the
end of inittab so when your box is restarted your filtering will continue to
work as desired. (/me shudders)
You need to modify your postfix /etc/postfix/master.cf like this:
(dont delete the stuff in between, just change the respective lines. LOOK
CLOSELY AT ARGS)
# ==========================================================================
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (50)
# ==========================================================================
smtp inet n - n - - smtpd -o
content_filter=filter:
filter unix - n n - - pipe user=someuser
argv=/usr/local/spamass/filter.sh -f ${sender} -- ${recipient}
The filter.sh file I have looks like:
#!/bin/sh
# File locations: (CHANGE AS REQUIRED TO MATCH YOUR SERVER)
INSPECT_DIR=/var/spool/filter
SENDMAIL=/usr/sbin/sendmail
SPAMASSASSIN=/usr/local/bin/spamc
# Exit codes from <sysexits.h>
EX_TEMPFAIL=75
EX_UNAVAILABLE=69
cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit $EX_TEMPFAIL; }
# Clean up when done or when aborting.
trap "rm -f in.$$; rm -f out.$$" 0 1 2 3 15
cat | $SPAMASSASSIN -d 127.0.0.1 -p 783 > out.$$ || \
{ echo Message content rejected; exit $EX_UNAVAILABLE; }
$SENDMAIL "$@" < out.$$
exit $?
You need to add a user to your box called "someuser" or whatever you like.
Probably should have settings in etc/passwd like:
someuser:x:UID#:GID#::/no/where:/sbin/nologin
Probably want to:
mkdir /var/spool/filter
chown root:someuser /usr/local/spamass/filter.sh /var/spool/filter
chmod 750 /usr/local/spamass/filter.sh
chmod 770 /var/spool/filter
Perhaps this helps.

Subject: [SAtalk] Postfix. How do I do quick set-up for SA? (NEWBIE)
I am trying to figure out what would be the least time consuming and
easiest way to integrate SA into postfix. Any ideas?
