Hi people!
I just switched one of my servers from Courier to Dovecot. Planned to do it anyway but had to do it faster after the discovery that courier [the version I had installed, at least] returns malformed headers for a few messages, causing Outlook Express to completely ignore them. Curiously, they were visible in Squirrelmail and Nokia Series60 e-mail client.
Overal I am quite happy but have one little problem. More often than not, I have to press 'Purge' button two or more times in order to actually remove the deleted messages. The fragment of Outlook's IMAP log is below. Interestingly, Dovecot 1.0.7 (on another server) does not have such problem.
Best wishes Eugene

Are you sure that they weren't removed the first time but Outlook didn't refresh its header listing?
I have seen outlook take its sweet time in updating its header listings with IMAP. I never thought that its support for IMAP could be worse than its support for POP3.
I have to deal with it just because of the varied users I support, so I have Outlook, outlook express and thunderbird all configured to see my message store just for experimentations sake. But I use thunderbird daily.

Is it possible that Outlook uses two connections? First one does:
IMAP: 00:46:56 [tx] 0yc9 UID STORE 172903 +FLAGS.SILENT (\Deleted
\Seen) IMAP: 00:46:56 [rx] 0yc9 OK Store completed.
The second one does:
IMAP: 00:46:58 [tx] 623w EXPUNGE IMAP: 00:46:58 [rx] * 102 FETCH (FLAGS (\Deleted \Seen)) IMAP: 00:46:58 [rx] 623w OK Expunge completed.
This happens because the session hasn't yet seen the flag change. Only
after EXPUNGE is finished it syncs the mailbox and notices the new
\Deleted flag. At that point the EXPUNGE handling is already finished,
so nothing happens.
So I guess the question is if Dovecot should first synchronize the
mailbox and only then perform EXPUNGE. This is allowed by IMAP, but it
would require Dovecot to do two mailbox synchronizations for each
EXPUNGE. I'd rather not do that but maybe Outlook is big enough user
that it should be changed...

Or of course Dovecot could just do another EXPUNGE if the first one noticed that some messages got \Deleted flags. I'll add to v1.1 todo list.

That would be nice. The delete and expunge commands were indeed issued by different IMAP-connections.
Was the 1.0.7 version handling the updates differently? Because I never had such delay with another account (different server, same dovecot configuration, same Outlook installation).

Now that 1.1 release is near, I wonder if you were able to add this feature? It would be much appreciated =)
