Here is a snipette from a thread where a fellow TriLUGger was front-ending his Exchange server with an external SMTP server (a linux box), and he was inserting a spam filtering appliance into the loop. I just installed a mail cluster for a client in which I replaced their external SMTP server with a linux cluster running Sendmail, Mailscanner, SpamAssassin, and McAfee's anti-virus scanner. It works a charm. The key here is to setup the external mailserver so that it accepts and relays mail into the internal exchange server. You can setup the external server as the end-point for the mail, and then forward on the mail using the aliases file (or virtual hosting), or you can simply set it up so that it relays. Either way, MailScanner will grab the incoming mail and apply your Mail policy rules, then it will scan the mail for viruses (using an external virus scanner like Sophos, Clam, or McAfee), and finally it will run the mail through SpamAssassin to rank it's spam-ability. After that, the mail is either relayed on into the internal exchange server, or it is forwarded into various users accounts. If you are going to use MailScanner (which I *highly* recommend - even if you don't use a anti-virus program), then just read the install docs and it will lay out the install of all the necessary parts. The nicest thing about MailScanner is that it lets you *easily* apply Mail Policies like: don't allow any attachments with *.exe, *.com, *.pif, *.scr, etc.... This alone will kill 95% of all the Windows virus flying around.
