I'm not sure about the absolute best spam filtering system but the
simplest lightweight solution (for me) is postscreen, SPF/DKIM and
Spamprobe via dovecot/sieve filters. I would prefer Dspam but it is
no longer available as a Debian package. Spamprobe is good enough as
after 1/2 a year of training I personally get about 2 spams per week
out of 20 to 30 spams per day that manage to get through postscreen.
I specialize in setting up lightweight containers, VPSs and DO droplets
where spamassassin/clamav, and even rspamd, will simply not work. I
don't bother with anti-virus software because most of my clients run
linux desktops and the few that don't use whatever comes with their
OS system or a commercial antivirus package.
Hi everyone. I was wondering which anti-spam and anti-virus programs do you all use with Postifx? Any advice on which programs work best?
I will add one more bit. I am one of the postmasters for mail.python.org. As such, I have nothing to do directly with the Postfix side of the shop. I maintain the SpamBayes (http://savages.org/) installation. Any mail messages which make it through the various Postfix steps are scored. Any which don't score as "okay" are held for list moderators. (Almost all arriving mail is headed for Mailman lists. The SpamBayes step is skipped for almost all individual aliases.) In addition to this use, SpamBayes is the only guard at the door for messages arriving by the Usenet-to-mail gateway, which Postfix don't see.
I'm not sure how visible the site-specific setup is, but I don't think there would be any problem sharing it. Back when Subversion was still used, it was managed there, but I suspect the mpo-specific SB bits got disconnected from source code control over time. Let me know off-list if there is any interest, and I'll see about refreshing it's scm with something more current.
