I'm going to implement a mailfiltering gateway for my company. I'm going to use Postfix, with a PostgreSQL back-end.

The question would be: how to best implement the antispam measures.

  • Mailscanner + SpamAssassin?
  • amavisd-new + SpamAssassin?

(Note: I don't need antivirus filtering)

I've been searching for up-to-date comparison between Mailscanner and amavisd-new, but most comparisons I found are severely out of date.

Can someone provide me an up-to-date comparison or a link to such?

TIA

Silly me. Just found out about this page:

http://www.postfix.org/addon.html

... and I quote:

mailscanner system, works with Postfix and other MTAs. WARNING: This software uses unsupported methods to manipulate Postfix queue files directly. This will result in corruption or loss of mail. The mailscanner authors have sofar refused to discuss a proper access API or protocol.

Case solved. amavisd-new, it will be.

Thanks for everyone who have tried to answer!

Could you accept this as the answer to your question? Would help other visitors and keep the site clean(er). – syneticon-dj Nov 28 '11 at 17:58
@syneticon-dj I'd like to, but it's still under embargo (i.e., clicking on the checkmark pops up a box "You can accept your own answer tomorrow") :) – pepoluan Nov 29 '11 at 5:01
BTW, as a side note: amavisd-new is working quite well with postfix. We're using it with AV scanners enabled, although technically there hardly would ever be a need due to configurable blocking by filetype - we just block executables and whatever is currently on the "potentially harmful" list. – syneticon-dj Nov 29 '11 at 9:12
@syneticon-dj I had dabbled with amavisd-new before, and honestly didn't find any grievances. However, someone in a mailing list mentioned Mailscanner, and that's why I asked my question. Anyways, thanks for sharing your experience :-) – pepoluan Nov 29 '11 at 17:12
