Hi Gregory,
I recently been testing Dovecot (the RPM version was 1.0-0_4_stable20050221.rh9.at) on of our RedHat9 servers using Maildirs. I am experiencing problem with Thunderbird 1.0 and 1.5 with message headers getting mixed up (i.e. you click on the message header in the list pane and it displays the message body of the next email in the list).
However when using Outlook Express (yes I have to admit I used it for testing!!) and Squirrelmail the messages are displayed correctly, which suggest it maybe a bug in Thunderbird. Interestingly I found a bugzilla report which looks like the same issue at: https://bugzilla.mozilla.org/show_bug.cgi?id=209561
I am gonna try switching back to mbox on the server and see if this fixes the problem (although I'd really like Maildir to work as its so much faster)

Subject [Dovecot] 1.0 beta3 not preserving X-Keyword header?
We've been putting 1.0 Beta 3 through the paces on our test system, and one of our users pointed out to me that Thunderbird's "labels" behave strangely on the new server. In fact, there used to be a header added to the message via IMAP when Thunderbird placed a label on a message, but as of the switch from 0.99.11 to 1.0beta3, this label header is no longer placed in the message.
Specifically, Thunderbird adds the "X-Keyword: $LabelN" header when you add a label to the message in tbird, where "N" is [1-9]. This works on dovecot 0.99.11 (RHEL4), but not on 1.0beta3. 1.0b3 doesn't seem to add this header at all, but rather seems to keep this information somewhere else. Perhaps
in the .imap indexes?
We're using mbox stores on the server. This was tested with both Thunderbird 1.0.7 (most widely deployed) and Thunderbird 1.5.
Aditionally, we've found that if the .imap index directories are removed, all the Thunderbird labels on messages seem to get "confused", too. I.e.,
if the user uses multiple machines throughout the day, changes in one client may not be reflected in another, when the user moves to a different system.
I'm still trying to get more details from the users, but have been doing preliminary testing that verifies this. One of the users complaining about this is my manager, who makes extensive use of Thunderbird's "Label" feature, so he's a bit nervous. :\
Another thing we've noticed is the potential for bad behavior if a use switches from the old dovecot to the new dovecot, which seems to be resolved if the .imap indexes are removed...
Let me know what other information is needed, and I'll do my best to collect it.
Gregory
