What's the best method to use SA?

2006-10-03 Thread Monty Ree 

Hello.

I have used SA using with procmail.
and clamav + sendmail(libmilter) against virus.

But I have found that other related solutions like 
http://www.mailscanner.info/ or 
http://www.amavis.org/. 

I don't know what's the difference or better between SA using procmail or 
above solutions.

more fast or more effective??

Anyone who uses above solutions?


Thanks...

  The original amavis is not well supported AFAIK.  However, it has a
descendant amavisd-new which is actively developed and supported.
  

  I don't know mailscanner, but amavisd-new is a much more efficient
approach for a mailserver, especially at ISP level.  The two main
differences are 1) Spamassassin (and clamav) get run once per incoming
mail, not once for every recipient, and 2) amavisd-new runs as a
daemon, so Spamassassin only has to be compiled in Perl once instead of
once per incoming message.

  *Lots* of mailservers use amavisd-new, including many ISPs and 3rd
party mail providers, FWIW.

I use Exim with the integrated SA ACL.
I'm really pleased with how it works.

We use SA, ClamAV, Razor, Pyzor, DCC, etc. with amavis-new and Maia Mailguard.  
Maia is a great way to imitate some of the big expensive spam filters out 
there.  It gives users a web front end for managing their spam and even their 
spam score limits.  It may be a little more than what you want to give your 
users, but none the less its a great admin tool for a network admin trying to 
stop spam.  In my case, I can go to the users that are getting the most false 
negatives and specifically tell Maia that this is spam, NOT ham now train 
bayes.  That to me is an awesome tool.  We also have a spam inbox setup, but 
nobody uses it and still wants to complain about getting spam.  Check it out, 
their web server always seems to be down so look at the Google cached version 
if you can't get their.
