There's plenty of options available, including Postfix and Exim, although
I still a fan of Sendmail for these kind of things.  All of these MTAs
will allow you to scan for viruses and such before forwarding the mail
onto your Microsoft Exchange server, if that's what you want to do.

If you decide to use Sendmail, which I would recommend, you can configure
a mailertable to forward mail for your domain to any MTA of your choice.  
You can find good information on configuring a mailertable db at:


For those who like Postfix and Exim, what advantages do you see?
