I'm sure either qmail or postfix are perfectly capable of doing what you want - indeed there are many posts about this very subject to the postfix mailing list. I'd suggest looking back through the postfix-users archive to read what has been said in the past. In particular you'll want to consider how to let postifx know what addresses @yourdomain are valid, so that it only accepts emails that are being sent to valid users. An example of how to do this can be found on http://www.plusone.com/gaptuning/postfix/ I looked at both postfix and qmail for dealing with email for my own small email server, and much prefered postfix. Oh and, <insert standard comment about how you should just replace Exchange with Postfix anyway> ;) Andrew
