Dear Sirs/Madams,
I have been attempting to properly integrate SpamAssassin into
Postfix and have not found the solution that I am looking for.
Currently I have Spamassassin running as a daemon (spamd, version
3.1.0a-2) which uses MySQL to store Bayes, AWL, user preferences and
stats. Postfix is currently configured to connect to spamd using a pipe
setup inside master.cf. Here is the current configuration:
smtp inet n - - - 50 smtpd -o
content_filter=spamassassin
spamassassin unix - n n - 50 pipe
user=nobody argv=/usr/bin/spamc -u ${recipient} -d localhost -e
/usr/lib/sendmail -oi -f ${sender} ${recipient}
This setup appears to work properly but I am concerned about what
happens when/if spamc cannot communicate properly with spamd. Currently
if spamd is not functioning or is dead, the message is passed through to
sendmail, instead of being deferred and placed back into the queue until
spamc can connect to spamd. I have modified the spamc flags to contain
-x (which is supposed to stop the graceful fall back), but sendmail is
still passed the message and it is delivered to the user.
I have already tried amavisd-new, spampd, qpsmtpd and a simple shell
script for connecting to spamassassin. None of these allow me to fully
use spamassassin's per user preferences and get proper fall back when/if
spamd is dead. I am hoping there is another option that I have not
tried yet. Any input would be greatly anticipated.
Thanks,
James
