dovecot - Jan 2010 - strange behaviour with seen/unseen messages in virtual folders.

Hi,

I've a virtual folder that contains unseen messages. When I mark the 
message and expunge the folder, the message should disappear. This works 
as expected in alpine. Alpine uses the following commands:

06000010 STORE 1 +Flags (\SEEN)
06000020 EXPUNGE

Using roundcube mail, the message wont disappear, when I perform the same 
steps. RoundCube Mails sends:

flg UID STORE 445 +FLAGS (\Seen)
exp1 EXPUNGE

But the message doesn't dissapear. But I can expunge it with alpine, as 
long as the folder contains one message. If it contains more messages, 
some or even all messages won't disappear. When I mark them as unseen/seen 
in alpine, I can expunge them with alpine.

The expunge command send by roundcube mail never expunges any seen message 
in the unseen folder. Whether it was flagged as seen by alpine nor 
roundcube mail.

kind regards,
matthias

That's because those are sent in two separate sessions. Actually my
original plan was that simply re-opening a mailbox would drop the
unwanted messages, so expunge wouldn't even be necessary then. But looks
like all this got broken when I optimized the code.. I'll have to figure
out some way to fix it.
