Example: IMAP folder with 548 messages (501 conversations) ranging in date from 2001 to present unexpectedly shows messages from 2003 as unread (bold, "View: Unread" shows them). When the same folder is viewed with webmail client (tested with hasty mail, horde, group office) the messages appear as seen. Reproducible: Couldn't Reproduce This appears to happen on multiple platforms (Mac and linux tested) and has been occurring since I started using Thunderbird, at very least since 3.0b1. Recently mentioned on the Dovecot users list which brought it to my attention as happening to other people besides me: http://www.dovecot.org/list/dovecot/2009-November/044575.html Perhaps it is related to dovecot in some way, but other clients don't seem to be a problem (as noted above).
As mentioned on the dovecot mailing list by Thomas Harold, I closed TB, deleted the msf file for the folder with the unseen old messages, started TB and the messages were listed as expected (seen).
Can't confirm a fix, but I can confirm this behavior as of 3.0b4. I see this daily on an account with over 100 mailboxes and a few GB of email across them. Messages just seem to randomly become "unseen" in a number of folders. Reindexing regularly is not much of an option since it renders TB unusable for an hour or so.

Perhaps its related to our use of condstore. You could try turning off condstore in the client by toggling mail.server.default.use_condstore in the config editor.
I've toggled use_condstore to false. At this time I have no messages showing as unseen that shouldn't be. I'll watch for a difference in behaviour.
What's odd about that is that condstore makes it so we don't even query the flags for the old messages, in general, so I don't know why we'd think they were unread, unless the mailnews backend code didn't realize that the imap protocol code was using condstore on that particular folder (though we certainly keep track of that fact)
Adding CONDSTORE to bug summary for ease of search. FYI. CONDSTORE was supported by bug 436151. > http://groups.google.com/group/mozilla.dev.apps.thunderbird/browse_thread/thread/08d88880d22fe73f Tb confuses relative number with UID?
Summary: Very old messages appear as unseen with IMAP → Very old messages appear as unseen with IMAP (CONDSTORE is supported)
CONDSTORE : http://tools.ietf.org/html/rfc4551 Issue in modseq handling?
I disabled condstore as suggested in comment 3 on 11/25 for all my running copies of TB3. I have not had this error occur since. I am now going to re-enable condstore to see if the problem returns.
Duping because patch is proposed to bug 517461. If wrong, re-open with attaching IMAP log, please.
