We've noticed some oddities which we can't figure out:
1) When siwtching a Thunderbird user running on a Fedora system(latest version of Thunderbird) Thunderbird couldn't see his mail folders even
when the appropriate checkbox (Server Settings -> Advanced -> Show Only
Subscribed Folders) was unchecked. Clearing out the IMAP Server Directory setting
seemed to fix this, but the very next day, the folders were gone again and we've
been unable since to get Thunderbird to see them.
Maybe TB broke its cache after the change. For a completely transparent UW-IMAP -> Dovecot migration where these kind of problems shouldn't happen see http://wiki.dovecot.org/Namespaces
Another problem with this same user involved a test whereinwe created a new mail folder and then deleted it. The deletion caused an
error message to be displayed (inferior folders, etc) but on the Mac OS X version no such
error occurred and the folder was deleted. Investigating the protocol traces for
Thunderbird showed that in the error case, it attempted to rename the deleted folder as a
subfolder of the Trash folder (thus generating the error message) but on the Mac OS X
version, it actually deleted the folder (which would seem to make more sense). The
settings pertaining to the Trash folder are the same on both clients.
Disable "Server supports folders that contain sub-folders and messages" setting. https://bugzilla.mozilla.org/show_bug.cgi?id=284933
UW-IMAP has this exact same problem, so I don't know why it wouldn't have happened with it (unless TB has some special UW-IMAP checking code).
2) When switching an Apple Mail.app user running on Mac OS X10.4.11 (Tiger) at the latest patch level, things appeared to work fine, and then
the user mentioned that no mail was showing up in her inbox. Closing and restarting
Mail.app appeared to fix that temporarily. She normally keeps a large number of
messages in her inbox (approximately 7000+) and receives a large number of
messages each day (several hundred).
No idea. I've used Mail.app for several years with Solaris+mboxes for my own mails..
solutions, or could point me to some ways of debugging these problems (with Thunderbird I can at least
debug IMAP protocol exchanges, but since dovecot doesn't log IMAP exchanges for specific IPs and
since the socket connections are all via STARTTLS I can't use tcpdump so I'm kind of at a loss for how to
track these things down short of patching the dovecot code to put in tracing messages).
