Seconded... Toss UW, and let the person installing mdk make the choice (cyrus or courier).



UW can't be tossed without a migration path. But maybe if someone can

Furthermore as I said the default (now "" again) mailsubdir path in uw-imapd which allows to get $HOME system files suggested as mail folders for subscribing looks very unprofessional and insecure... (and it happens basically in any mail client other than mozilla...).

test uw->dovecot migration now that it's in contrib.

uw -> dovecot migration is transparent (but only if users
place their mailbox in "mail" or "Mail"); but this isn't
in latest uw-imapd (after removing of mailsubdir path). Nor
there is a way for getting it totally transparent, since dovecot use the $HOME/{mail,Mail}/.subscriptions while uw-imapd uses $HOME/.mailboxlist file.
Anyway it seems promising but I don't see it so better performing than imapd. It uses
indexes for mailboxes, and that's speed up, but on the other hand the INBOX is in /var/spool/mail/ and needs to be reindexed every time, since INBOXes are accessed
at the same time but the MTA (which could be postfix, sendmail, etc.).


IMHO one of the cause of the claimed poor performance of
uw-imapd mailbox based vs maildir(s) one is that end USERS don't understand
that thay could have other folders than INBOX which is generally
left grown indefinitely (so for every new messages,
the whole scanning needs to be redone). The second problem
is that IMHO using uw-imapd under xinetd doesn't give the
best performance on connection (maybe there is a way to use
it as standalone daemon).



Personally I my vote is for cyrus, but I know others prefer courier.
(How about moving cyrus & courier into main?)


Depending on how dovecot performs (and the features, but it looks ok),
maybe dovecot would be better in main (as the default imap server), and
if there is space, cyrus.

Why don't do a serious test with uw-imapd, cyrus-imap, courier-imap and dovecot, but with a certain amount of messages, i.e. more than 10000-20000 or 50000 messages per users, and with multiple user SSL accesses at same time?

Bye.
