I'm looking for an extremely lightweight mail server to handle IMAP/POP3 connections. Maildir backend preferably, with multiple authentication modes (SQL, LDAP, etc).
Any suggestions?
Solution 1:
If you are using *nix for your platform, dovecot is pretty much the standard. Nearly every unix distro has it available in its ports / package management system.
If you are on Windows, hmail may be a fair choice.
