I need to set up a mail transfer agent on our server and am looking for a good free one.

I need it to handle multiple domains and allow forwarding of emails for those domains to other email addresses (ie. no mailboxes)

I did some searching and Exim seems to be reasonable ... anyone have experience with this or have other recommendations?

Thanks in advance

How about the Microsoft IIS 6.0 SMTP Server that is included with Windows Server 2003?

I completely overlooked that, thanks – Adam Fox Aug 26 '09 at 19:28

I have used Exim in the past for a multiple-domain mail server with all sorts of forwarding and mailboxes, etc. Very good experience, I can only recommend it. Specifically when used in combination with ClamAV (Antivirus) and SpamAssassin (not sure whether these two are available for MS Windows, our mail server ran Debian GNU/Linux).

Depending on your requirements, Exim can be a tad complicated at first, but it is very powerful, highly configurable and extremely versatile. And for the admin side of it, you may as well have a look at vexim, a web-based admin interface.

Thanks for the answer, but I gotta go with the IIS option – Adam Fox Aug 26 '09 at 19:28
