Each of these MTAs have similar features. All of them can handle large amounts of mail; can interact with databases in many formats.
But, I prefer Postfix and i use it in all my servers, it's easy to administrate, secure and robust.

Can I plug citadel instead? Simply for the easy setup and the many features that it has. It is more than just an email server - boasts group-ware and advanced communications functions with a web-based interface. It may be worth considering if you are intending to grow your service beyond just a plain MTA.

From the website: email, calendaring/scheduling, address books, bulletin boards, mailing list server, instant messaging, multiple domain support, modern AJAX-style web interface.
