Well, we do this every day... Postfix with access map and a transport map. All mail comes in to postfix servers, marked for spam and scanned for viruses (using Vexira). It's then forwarded onto either a Linux or Exchange 2000/2003 server based on domain. Basically get the mail server running as a normal mail server but instead of creating local accounts just setup the transport mapping. Not much to it. Gary

We want to move to something a little more capable, that has collaboration built into it, etc, etc. Management is leaning towards MS Exchange, I'm staying neutral for now. I'm researching many different vendors, and finding out that most ALL of them really suck at anti-spam and anti-virus. And I really don't want to pay out the nose for a antispam/antivirus appliance that doesn't use SA and/or our preferred antivirus product. (Let alone running antivirus on what amounts to a database server - that makes me twitch.) I'm leaning towards setting up a "man in the middle" server that is strictly a relay...that uses Postfix + MailScanner + SpamAssassin to scan and categorize incoming and outgoing emails. I simply love SpamAssassin too much to give it up. Can anyone point me to a document that details how this is done, or gives pointers? I tried doing some Google searches, but I didn't find anything. I'd really appreciate any help offered...getting this down would remove the need for me to have to compare all these products based upon what spam/antivirus measures they have...and they're all amazingly behind with the times. -- Jake McDermott
