setup a spamassassin/mail scanner gateway server

[vandensype]

Hello all,
I was wondering if anyone knows of any good links or guides on how to set up a mail scanner/spamassassin gateway server.

Basically, I just want to setup a small box running, for example, postfix/SA/MS that will tag all emails and subsequently pass them on to my companys (ack!) Exchange server. The exchange server will still need to be accesible from the outside however as people need to be able to still use the outlook web access feature for remote mail checking.

Any thoughts would be appreciatedd. I have done some searches here and at tldp.org but could not find any specific step-by-step guides ( I'm somewhat of a noob regarding this).

While I don't have experience setting up as you describe, I do want to point out that Exchange will only need to be accessible via port 80/443 for OWA. In fact, it might not even be the Exchange server since you're probably running IIS on a different box (OWA is actually served via IIS, it just fetches the information from Exchange transparently to the user).

ignore the BSD specific stuff. The rest of the howto works great.

Thanks for the info, although I am not at all familiar with BSD, I will try and interpret the info for linux.

I have done just such a thing using Sendmail, MailScanner, ClamAV, and SpamAssassin. Below are the appropriate links.

MailScanner - http://www.sng.ecs.soton.ac.uk/mailscanner/install/

ClamAv - http://clamav.elektrapro.com/

SpamAssassin - http://eu.spamassassin.org/index.html

Post any specific questions you have about this setup and I'll do my best to answer.

The BSD stuff is minimal, and shouldn't affect how you configure the programs, as given in the examples.
