Limiting outbound SMTP spam checks

[Dean Ericksen]

I have a non-traditional network architecture – I need to run spamassassin against all inbound SMTP (generally messages to sympa email lists), but not invoke spamd when sending outbound messages. I realize this must be easy, but I can’t get my head around it right now.   The smtp entry in my (postfix) “master.cf” file is:   smtp    inet    n       -       y       -       -       smtpd         -o content_filter=postfixfilter:   postfixfilter unix - n n - - pipe         flags=Rq user=postfixfilter argv=/usr/bin/postfixfilter -f ${sender} -- ${recipient}     …and “/usr/bin/postfixfilter” looks like:   #!/bin/bash   /usr/bin/spamc | /usr/sbin/sendmail -i "$@"   exit $?       Any thoughts appreciated.     -Dean ONE/Northwest
