Hi Kenneth ...

You should try amavisd-new :)

Works great ... just google for it.

Subject: Postfix anti-spam solutions...

Happy happy folks, hope 2006 will be another great year for all of us.

I'm looking for some suggestions on building a better mail server than
I currently have running on various locations... Below is my current
configuration

Postfix 2.2 *
MySQL 4 *
Courier-IMAP 4 *
Spamassassin *
MailScanner

ClamAV *

Now, I'm looking to drop MailScanner. I'm getting fed up with the way
it hogs resources, but the ones marked with an * I'm not willing to
part with. Basically I only use MailScanner for clamav, spamassassin
and some content restrictions like maximum attachment sizes and
blocking file types like videos (per client basis). I also make use of
Mailwatch to monitor my MailScanner and get various graphs, reports,
etc...

I'm also looking to bring in these additional pieces of software to help:

= policyd - policyd.sourceforge.net - For grey-, black-, and
whitelisting. Throttling, spam traps, etc... Looks very good, and it's
homegrown.

= Razor/Pyzor/DCC combo. My idea here is to have all my mail servers
share spam information between themselves, and make use of a third
party as well. Are these the correct ones to look at. It would be
grand to be able to train a single spamassassin, and have other
servers use one of the above (if possible) and get their own
information accordingly.

= altermime for footers, some clients require this...

= TDMA - http://tmda.sourceforge.net/challengeresponse.html -
investigating this one for enabling it only when a client requests it.

I take it that I would replace MailScanner with amavisd-new. Had a
quick glance over the features and the FAQ but I'm missing the ability
to be able to limit attachment and/or message sizes per
recipient/domain. Can this be done or do I need something else?

Ultimately, I need something that is blistering fast, safe, gives good
results and can easily be used over multiple servers... I'll also be
writing my own web-interface for managing to whole lot, that is why
SQL look ups are very important, especially if the queries themselves
can be tweaked to give better performance and more flexibility to the
underlying data structures.

Any suggestions would be appreciated.
