IMAP

IMAP servers

There are basically three main IMAP server solutions:

UW IMAP

IMAP server developped by the University of Washington. Uses a proprietory mailbox format mbx, which is more or less a binary version of the usual mailbox format. A binary package exists on cygwin, but it regularly suffers from locking problems. A patch exists to use maildir format though, but patch seems outdated.

Courier IMAP

Courier-IMAP is a fast, scalable, enterprise IMAP server that uses Maildirs.

Cyrus IMAP

Developped by Carnegie Mellon. Also uses a private mailbox format.

Courier IMAP on openSUSE

Binary package for Courier IMAP is available on openSUSE (package courier-authlib and courier-imap). However it conflicts with the default IMAP server, (UW IMAP), which must first be uninstalled.
