Have you tried posting on the 'Spamassassin' list also? That is
probably where this message belongs. The DKIM problem should be
directed to the Postfix forum for best results.

postfix + spamassassin via milter
I running postfix from ports. I would like to block as much spam as possible during the SMTP session. Currently I am make liberal use of RBLs (direct in postfix configuration) and also using SPF using the spfpolicy daemon. I would like to add spam assassin to the list (and possibly clamav). Most of what I see about integrating spam assassin with postfix requires that the mail be accepted for queueing before spam checks are run. I would prefer to reject the mail after DATA during the SMTP dialogue. I see that postfix now does sendmail style milters. Is that the recommended way to go with this? I see that there is a mail/spamass- milter port. I anyone using that with postfix 2.4.3? Thanks. -j -- Jeffrey Goldberghttp://www.goldmark.org/jeff/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Furthermore, I also wish to reject mail early which is addressed to invalid usernames, and such a proxy doesn't do that (without a great deal of work and more things which can break). However, if I were trying to protect something like an MS-Exchange server, I would definitely consider using a proxy in front of it. However since I've got postfix with its power and capabilities, I won't go this route.

Here is what I have working so far. Straight from ports p5-Mail-SpamAssassin-3.2.1 spamass-milter-0.3.1_3 postfix-2.4.3,1 To get postfix to use the milter, I added # milters for spam assassin milter_default_action = accept smtpd_milters = unix:/var/run/spamass-milter.sock to main.cf Note that the milter_default_action setting is so that if I mess up the milter, mail still goes through. I may set this to tempfail once I am more confident. Also to allow postfix to talk to the milter I added spamass_milter_socket_group=mail spamass_milter_socket_mode=664 to /etc/rc.conf (in addition to the _enable variables). I will submit a PR with an addition to the documentation explaining how to do this with postfix. What I've been having the most difficulty with is spammassassin itself. It runs correctly as the spamd user (note that this is *not* the spamd which is the BSD tarpit, but is a daemonized spamassassin.) but it still seems to think that is also running as user root and so tries to write things in /root/.spamassassin Now if I change the ownership of that spamd then everything works fine, but I really don't want my bayes and whitelist database on the root filesystem. I can (and have) manually set the paths for the bayes data and the autowhitelist data to a more appropriate location, but the later path setting feature appears undocumented, and I still haven't figured out what path variable to set for the user preferences (so each time mail comes into the server, spamassassin, run as spamd, tries to read /root/.spamassassin/user_pref. I'm sure that I could probably trace out the separate configuration variable to set that to the right location, but I'm wondering why spamassassin is looking in root's home directory at all instead of the spamd home directory. -j -- Jeffrey Goldberghttp://www.goldmark.org/jeff/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
