We can confirm this is an issue on beta3, and we had hoped beta5 would solve it. :/

I'm not certain this is Thunderbird-specific though, as we have users with one Tbird and a Treo checking simultaneously running into this issue as well...

Hi Timo,

I have been having the same problems. From my experience, the problems seem to originate when I try to run Thunderbird on on one machine when it is already running on another machine. If I always close Thunderbird and only allow myself one open at any time, it doesn't seem to happen. When it does happen, the only way I can find to get it to work again is to quit all instances of Thunderbird, and, on the server, kill dovecot, and then go to my Maildir directory and rm dovecot*, then restart dovecot, then restart Thunderbird. I don't think there are any network or router issues, because I get the timeouts even when I run on the server and use localhost as the server in Thunderbird. The new beta5 has the same issues. It takes some time (about 12 hours of normal email use for me) to get into the situation where Thunderbird reports timeouts, and I have to go do the above procedure.

Well, I've fixed some problems related to IDLE command and possibly it could have caused other problems also. Could you try downloading latest nightly snapshot from http://dovecot.org/nightly/ and try with it? I guess I should release it soon as beta4..

If it still happens, I can't think of anything else in Dovecot that could cause it. Have you checked that there are no routers/firewalls in the middle that limit the connections in some way?

Hi guys,

So is there resolution to my query below? Is this a bug in beta3?

Thanks.

Hi guys,

I've got a client running 1.0.beta3 on SuSe 9.3

Everything has been running perfectly since it was installed about 6 months ago, but lately they've had issues with email clients not being able to connect to the IMAP server, until they close their clients(Thunderbird & Outlook) and then re-open them.

They have roughly 70 users on their network, so it sounds like it could be too many active sessions at once, but I've tried changing a few things in the config, and so far nothing has resolved this.

Any help would be appreciated.

Regards.

Also, just to be clear, though we are running into this problem, we do* seem to be seeing it less often, perhaps in part due to beta 3->5 fixes? I've also noticed that IDLEing users do* get kicked at some point, which never happened under beta3.

So, we're still very happy with the improvements so far! Keep up the good work Timo!

Agreed I don't think it's just a Tbird issue as I have users having the same problems using Outlook...

Thanks.
