hMailServer is a free email server for Windows created by Martin Knafve. It runs as a Windows service and includes administration tools for management and backup. It has support for IMAP, POP3, and SMTP email protocols. It can use external database engines such as MySQL, MS SQL or PostgreSQL, or an internal MS SQL engine to store configuration and index data. The actual email messages are stored on disk in a raw MIME format. It has active support and development forums.

Common features such as multiple-domain support, aliases, catch-all and basic mailing lists are present. Users can be authenticated both against the local hMailServer user system and against an external Active Directory.

hMailServer offers a number of different AntiSpam mechanisms:

  • Server side rules (rules for individual accounts available in v5)
  • Retrieval of messages from external POP3 accounts
  • Quotas on domain, mailbox, and individual message sizes
  • Plus addressing (using + to make a virtual alias for an account specific to a task, as seen in Gmail)
  • Attachment blocking (based on attachment extension)
  • Custom SMTP routes for specific domains (can be used to set up MX backup, forwarding and more)
  • API (it's possible to write hMailServer scripts using VBScript and JScript)
