There was just another mail about AIX having problems with timezones
(Subject: Time zone problems with dovecot-1.0-stable (20050705 nightly
snapshot)). Maybe look at how that thread continues if you have the same
problem.

One thing I've seen with Linux+JFS is that directory's mtime wasn't
modified when new files were added to it, which broke maildir's new mail
checks. But maybe this was a bug in some specific Linux version. If
anyone is running JFS, I'd like to know if this problem still exists..

One possibility is to let Dovecot autodetect the mailbox location. It
checks for ~/Maildir first and ~/mail second. It's probably the easiest
way, but if some users have created ~/Maildir accidentally you'll get
into trouble.

Another possibility is to specify separately for each user where their
mails are stored. But if you're going to be using NIS as userdb, this
isn't possible..

http://wiki.dovecot.org/moin.cgi/Migration and
http://wiki.dovecot.org/moin.cgi/Namespaces will also help how to do the
change transparently to users.
