dovecot - Oct 2007 - Messages not marked as read

Hello everybody,
  Recently I have migrated my IMAP server from Courier-IMAP to
dovecot. The migration was successful and all the users are happy due
to the speed of  the new IMAP server. We are using Horde-3.2+IMP-4.2
as the webmail client.
But one of the users is having some unusual issues with his mailbox.
Whenever he clicked and open a new email, it's never marked as read.
He has to click and open several times  to get it marked as "Read". I
checked the dovecot version and found that we have a unstable version.
So I upgraded to the latest stable version(1.0.5). But still
occasionally he has the same issue. Does anyone have experienced
similar issue.

Please share.
regards

I think you should first figure out if this is really a Dovecot problem
or something else. You could for example enable rawlog
(http://dovecot.org/bugreport.html#sniffing) for that one user and then
when this problem happens look at the logs to see if there is a command
that updates the \Seen flag.

I don't know how Horde/IMP updates the \Seen flags. It might be a real
STORE <uid> +FLAGS \Seen command, or it could use FETCH BODY[] which
also sets the flag implicitly.

You could also modify mail-log plugin to log \Seen flag changes. You can
do this by replacing MAIL_DELETED with MAIL_SEEN in
src/plugins/mail-log/mail-log-plugin.c (and "deleted" /
"undeleted"
texts also with "seen" / "unseen").
