XMail is an Internet and intranet mail server. It featuring an ESMTP server, POP3 server, finger server, TLS support for SMTP and POP3 (both server and client side), multiple domains, no need for users to have a real system account, SMTP relay checking, DNS based maps check, custom (IP based and address based) spam protection.

XMail also provides SMTP authentication (PLAIN LOGIN CRAM-MD5 POP3-before-SMTP and custom), a POP3 account syncronizer with external POP3 accounts, account aliases, domain aliases, custom mail processing, direct mail files delivery, custom mail filters, mailing lists, remote administration, custom mail exchangers, logging, and multi-platform code.
 
This server born due to the need of having a free and stable Mail Server to be used inside my old company, which used a Windows Network. I don't like to reinvent the wheel but the need of some special features drive me to start a new project. Probably if I could use a Linux server on my net, I would be able to satisfy my needs without write code, but this is not my case.
