dovecot - Dec 2010 - Migration from UW-IMAP

I am attempting to test out dovecot on a server on a separate IP address from
the live, functioning UW-IMAP. I am having mixed results with dovecot. An
entirely new account that's never been used with UW-IMAP seems to work fine,
but that's really not the point of the exercise.

If I try changing over an existing account to use dovecot, I get a variety of
issues. Testing with Apple Mail.app, if I synchronize the account, the INBOX
stops displaying. So off to plan B, and debug via command line commands.

I tried connecting to Dovecot. It was able to list the mailboxes for me. I asked
for status on INBOX. Sometimes I get an error back in the IMAP stream, sometimes
not. Either way, the log shows complaints about creating mail/.imap and below
(we use mbox format, plus /var/mail/%u for inbox).

I have active namespace compatibility recommended by the Wiki so that clients
specifying "mail/" and clients not specifying an imap path both work.
With the test account, I proved this functionality is working.

At this point I clearly have some issues, and could use some help figuring out
what to ask for help with, i.e. how to proceed to debug this without damaging
the existing UW-IMAP setup in the process. The goal is to cut over to dovecot
once I can be sure it really is working compatibly, but until then I have a
large user base and can't blow everything up.

And yes, I really, truly have RTFM (i.e. read the Wiki, the troubleshooting
pages, the migration pages).
