Mail servers: the good, the bad ...
Below is a list of servers I have seen for Linux. Has anyone had any experience with any one of these?
PS - I would have just inserted the link but the program on this site will not let me do so ...
Unix/Linux mail servers

If you don't need a mail server on your machine, but just access to a mail server to send mail through try Fastmail.fm (They do not, of course, allow spam.)
See also LDAP servers
Internet (POP3 or IMAP4, SMTP):
* AXIGEN Mail Server. "Fast, reliable and secure mail server for Linux, offering (E)SMTP, POP3, IMAP4 and WEBmail services, with centralized Web/CLI Admin and FREE support included, enabling the System Administrator to have full control of the email traffic."

Formerly OpenMail, here is how HP described it: "OpenMail is HP's strategic business messaging and collaboration solution for Linux and UNIX systems, based on Internet standards. Perhaps its most notable feature is the way that it offers a choice of desktops, including Microsoft's Outlook. No other non-Microsoft server supports the richness of Outlook as deeply as OpenMail, including support for calendaring, wide-area scheduling, public folders and delegation. OpenMail has an installed base of 15 million seats, with representation in 60 percent of the Fortune 1000.

* Courier by Double Precision, Inc. "The Courier mail transfer agent (MTA) is an integrated mail server suite that provides ESMTP, IMAP, POP3, webmail, and mailing list services within a single, consistent, framework.

Courier can function as an intermediate mail relay, relaying mail between an internal LAN and the Internet, or perform final delivery to mailboxes. Courier uses maildirs as its native mail storage format, but it can also deliver mail to legacy mailbox files as well."
