I tested Dovecot briefly on OpenBSD, and lost mailboxes. No idea what
happened, but UW-IMAP has been much more forgiving, especially when
compiled with MBX support for faster mailboxes. Looking to move to
Cyrus, for the single message store (e-mail to multiple recipients
stored once, something maildir does not handle), and for the features we
need at work (Kerberos, shared mail boxes).
