I have used UW-IMAP and now use Dovecot because it's just plain fast.I'd check /etc/dovecot.conf to see if there's any special settings, likewhat the namespace is set to, specifically mail_location = which ifdefaulted, is $HOME/mail and which is why SM thinks you should have thatset to "". It might have been changed to match your old server. If itwas, leave it alone as you found it to work. I'm kind of a 'purist'(whatever that means) and preferred to change from SM settings of mail/as the setting and liked the "" setting for Dovecot because that meantwhen I helped others setup their IMAP email in SM or whatever, I couldjust leave that setting alone and it would work 'out of the box.' Forgoing forward, I find that the less things have to be 'tweaked' to makethem back-compatible, the happier I am as an admin.
Just my thoughts...
