[Dovecot] 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.

#dovecot --version 1.0.rc15 First try upgrading to a more current version. 1.0.rc15 has got to be a year

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?

"Connection reset by peer" means the connection was closed by the
client (or something in the network), not Dovecot.

"Connection reset by peer" means the connection was closed by the client (or something in the network), not Dovecot.
Such disconnects may be due to a router or a firewall (or something like an ADSL modem/router) which sets a timeout on idle TCP connexions (reflexive ACL, NAT mapping...). It is frequent to have no more than 5 minutes timeout. Workaround is to force the client or the server to keep the connexion alive by sending some packets at an interval less than 5 minutes, for example by polling new mail every 3 minutes.
