Postfix Anti-Spam, Anti-Virus Relay Server for Exchange Server 2000/2003

[denbert]

Hi there,

I'm having a Exchange 2003 server and are getting mails from my web hotel via the POP Connector, and are using the Exchange to send SMTP outbound.

I'm having more and more problems with this setup, as mail administrators are setting their mail servers to check with MX DNS - as my OUTBOUND IP is different than the MX Record IP, the mail are blocked.

I'm not happy of the idea of routing SMTP directly to my Exchange Server.

I've read this http://www.howtoforge.com/mandriva_p...virus_exchange with great interest, but I'm having a Debian "Etch" server running - Anyone got a similar howto for the Debian "Etch" server?

Anyone please

I'll try this very interesting howto The Perfect SpamSnake - Ubuntu 8.04 LTS

You must create a proper SPF record for your domain.
