Re: Spam Fighting moved from MUA to MTA - success!

[Aristotle]

Uhm, am I missing something, or couldn't you simply use spamd/spamc?

From what I understand, spamc/spamd are command-line tools meant to work on one item at a time. There's no real place to plug those in at an MTA level. They work fine from an MUA level, but at that point, I'd still be calling it 10 times instead of once for each MIRV.

With amavis, I get to make one call to SpamAssassin per incoming MIRV, and that's the big win.

You certainly can plug them in at MTA level. I've not much idea about postfix; but I've had it working in exim. You basically set it up as another transport, round-trip everything through that transport and set a flag so that you're not going round in circles.

spamc/spamd certainly are command line tools, but isn't everything?

No. The interface from postfix to amavis and back is SMTP. No launching and unlaunching. In fact, the interface to amavis is something else (LMTP?) that both postfix and amavis understand that permits individual senders to be accepted/rejected, even though only one copy of the message goes forward.

It's all incredibly slick. I'm really happy with it.
