dovecot - Mar 2008 - outlook2007 shows frequent imap disconnect no matter what outlook-idle setting in dovecot.conf

Hello,
I saw the problem quite often in various posts but could not find a real
solution .
Problem is that I frequently get annoying popups from outlook 2007 about imap
idle timeouts which block working with outlook until the popup is acknowledged.

The popup says:
 Your IMAP server closed the connection. This can occur if you leave the
connection idle for too long.
 Protocol: IMAP
 Server:     testhost
 Port:         143
 Error Code: 0x800CCCDD

I tried to run dovecot with or without  "imap_client_workarounds =
outlook-idle" but do not see any difference.
I am running dovecot on Red Hat Enterprise Linux Client release 5.1 (Tikanga).
Below is the output of some commands to get a clue about my config.

Background info:
Our primary mailboxes are on exchange servers.
As there is a size limit on the server mailboxes I am evaluating a local storage
solution for our users.
Thus  I set up an additional mailbox in outlook using IMAP.
Local .pst files can not be backuped easily (especially when outlook is running)
and I am investigating a local IMAP server where users can move their mails to.
This server can easily be backuped (even incrementally when using Maildir) and
users do  always have access to their mails.
The drawbacks are that users must have an extra login to the imap server because
I have no ldap access to the company AD server from our local site domain.
The solution will not be accepted though if I can not prevent the frequent
disconnect popups.

Peter

First try upgrading to a more current version. 1.0.rc15 has got to be a year 
old by now. You can get a newer rpm at atrpms.net.

I do have the same problem with dovecot 1.0.10 : disconnection popups 
with Outlook 2003/2007 with this kind of line in the logs:
dovecot: 2008-03-26 15:16:01 Info: IMAP(user): Connection closed: 
Connection reset by peer

in my experience it?s a general Outlook problem, no matter which 
version. I?ve seen this with uw and courier imap. I think it is related 
to the way how MS handles idle timeouts...

Greetings,

  Mike

I updated to the latest rev from atrpms.net which is 1.0.13 and I see the same
behaviour.
No matter if I set "imap_client_workarounds = outlook-idle" or
"imap_client_workarounds =" I get those disconnect popups. It seems
that the setting has no effect.

Is there someone who had success by applying the setting with outlook 2007?

  Peter
