I then would imagine you would benefit from the power of the Cyrus-IMAPd. Because of it's capabilities is requires more understanding and energy to set it up properly. Especially the interaction with the MTA (Sendmail, Postfix, Exim) is not prepared on Fedora Core in a way so that it immediately works after installation. Though it is not a real problem. Dovecot can be high-performance too either with mbox or Maildir usage. Dovecot does indexing, see http://dovecot.org/doc/mail-storages.txt I think you will have to read both IMAP/POP3 server's documentation a bit to see what you need regarding features, complexity and your skills. Performance shouldn't be a real problem with both. The uw-imapd is not a good performer speaking about larger systems. For the Cyrus-IMAPd see http://asg.web.cmu.edu/cyrus/download/imapd/ I would vote for Cyrus-IMAPd because I like it's features.
