[Users] "Read" status reversed on IMAP account

Wed Sep 4 19:05:34 CEST 2013

Hi

I have been using Claws-Mail (3.9.2 from Debian testing repository) for
few days. Mostly everything works as expected, but there is one thing
that does not.

Claws-Mail goes "crazy" for one particular IMAP account and inverts
"read" status for all messages - that is, messages that are read are
marked as unread, and messages that are unread are marked as read.
It always happens after checking for new mails. Usually first check
triggers this behavior. The next one "fixes" it, that is brings status
of all messages to correct one. Next one will invert statuses, and next
one bring them back. That goes repeatedly.

There is picture showing this issue:

At upper part is browser window with webmail for this account opened;
at lower part, there is Claws-Mail. As you can see in webmail, there is
only one unread message (marked as bold), received at 13:34. But
Claws-Mail treats this one message as read, while all others as unread.

Since this happens only for this one account (I am also using two other
IMAP accounts and one POP3 account), I can believe that this is
problem with server configuration. But since I know nothing about IMAP 
protocol, and "tech" support of company providing service will most likely
dismiss my concerns with "use one of supported e-mail clients" message,
I write to you first.

So, questions are:
1. Is this known issue in Claws-Mail? If so, is there workaround for it?
How can I apply it?
2. If it has been not reported yet, how can I get meaningful
debugging information for Claws-Mail developers?
3. How can I check if this is problem with company server?
If it turn out it is, how can I prove them that problem is on their end?

Thanks in advance for tips, pointers and answers.

I am attaching output of claws-mail -v and part of network log (with
HTML-style comments between) below. Please let me know if additional
info is required.
