there is Dovecot aswell.

If Id were you Id use one that you can intergrade with a Windows Virus Scanner.
Eg. ClamAV. And Id also make that a IDS can check it.. eg. Snort.
I havnt set this up yet.
but I have heard about a cool Linux System for Servers. Its kinda like this

Bind ClamAV to SendMail for scans. Bind Squid to ClamAV. Bind Snort to Squid, SendMail and ClamAV. Put it in a ChrootJail. And Install SELinux.

Basicly you get:
SeLinux+IPtables(CHROOT{Snort -> (Squid -> ClamAV -> SendMail)})


Then everything is holding everything.
But as I already said I havnt tryed this ever...
