Has anyone used Postfix as an e-mail relay server?
I am trying to replace a Linux box running Sendmail and SpamAssassin. The Linux box sits in our DMZ and acts as the MX for our domain. It receives inbound e-mails, scans them with SpamAssassin and forwards them in to our Exchange server for local delivery.
I'm trying to set up the same scenario on an XServe I just installed in the DMZ to replace the aging Linux box.
Question is: 1.) Is it possible? (I'm pretty sure it is)
2.) Any caveats doing it on OS X?
