A great idea, but I would like to use SA instead of DSPAM, because I
have already spent too long setting it up.
I added this into postfix's master.cf so that SA would parse the email
before:
smtp inet n - - - - smtpd
-o content_filter=spamassassin
[...SNIP...]
spamassassin unix - n n - - pipe
user=nobody argv=/usr/bin/spamc -f -e
/usr/sbin/sendmail -oi -f ${sender} ${recipient}
Interestingly, SA did identify the spam (address was blacklisted), but
still accepted it for delivery. Also, logging is logging duplicate
lines, or something is being called twice! Weird.
