You can compile Dovecot from the official sources (apply the patch before), download/install Dovecot from Mercurial (hg.dovecot.org) or open a bugreport for the package maintainer so that the bug can be fixed for your distribution. -- Daniel

[Dovecot] Director and CRAM-MD5
by Martin Spuetz 20 Oct '10

20 Oct '10

Hello, i have a setup with two director servers pointing to two backends. I don't care that much for load balancing, my main goal is high availability. CRAM-MD5 auth is working fine if I connect directly to the backends, but the director only supports AUTH=PLAIN because of the static passdb. director config: > passdb { > driver = static > args = nopassword=y proxy=y > } > > director_servers = director1 director2 > director_mail_servers = backend1 backend2 backend config: > passdb { > driver = vpopmail > args = > } > > userdb { > driver = vpopmail > } It seems that the director is only working, if I use the static passdb?! How can I use the director with other passdb drivers than the static one? Greetings, Martin

[Dovecot] 2.0.3 crashes

[Dovecot] Campo de quota en LDAP
by Antonio Perez-Aranda 20 Oct '10

20 Oct '10

En un principio, en los ldif que tenemos de los usuarios de prueba, tenemos el campo mailQuota. Sin embargo, si nos vamos a los schemas de qmail medianamente, con algo más de 3 años, se cambió mailQuota por mailQuotaSize y mailQuoatCount. Esto se debe entre otras cosas a que en la cabecera del fichero maildirsize del buzón, tenemos esta información, es decir, máximo tamaño ocupado y máximo número de mensajes. En el ldap de producción se sigue usando mailQuota? En el courier que tenemos montados aquí, misma versión y misma configuración que la existente en desbuz03, cuando no existe la quota del maildir directamente no da información sobre quota. ¿Estamos usando la quota de ldap? O al entregar un correo mediante Exim, se actualiza el fichero maildirsize con los valores de mailQuota. En este caso, podemos seguir con este comportamiento, o podemos utilizar la información que viene de ldap si no hay nada en el maildirsize.

[Dovecot] threaed ordered subject algorithm

We have custom plugins for squirrelmail which use thread orderedsubject, but according to capabilities dovecot only support thread by references algorithm. At present, we are using Courier with this capabilities (two algorithms are implemented). Could we use orderedsubject in dovecot?

[Dovecot] Outlook problem when deleting mails
by Ulf Jaenicke-Rößler 20 Oct '10

20 Oct '10

Hi, I'm seeking advice to solve the following "mystery": I set up an IMAP server on Ubuntu 10.04 (dovecot 1.2.9). It appears to work fine apart from one problem. A colleague is running Outlook 2007 on Vista and sometimes (sometimes very often, sometimes only occasionally) when he wants to delete mails, Outlook hangs for some time (he says about 1, 2 or 3 minutes) until it finally puts out a message box: "The server did not respond to this IMAP command before the connection was terminated" I have activated the outlook-idle workaround, but I learned that this doesn't do anything anymore, right? There's no error message in dovecot's logs. Nevertheless, today I found this around the time the error happened: 2010-10-12 17:13:02 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:13:03 imap-login: Info: Login: user=<user>, method=PLAIN, rip=192.168.100.53, lip=192.168.100.20 2010-10-12 17:15:07 IMAP(user): Info: Disconnected in IDLE bytes=272298/631645 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=63/539 2010-10-12 17:15:07 IMAP(user): Info: Disconnected: Logged out bytes=462/47082 What exactly does "Disconnected in IDLE" mean? Could the error be related to the same time stamp? (I'm not yet sure, if it always happens this way if the error occurs) I also found "Disconnected in IDLE" for other users at other times, but no one other complained so far. Maybe, that's because most of the other users use Thunderbird ;-) Is this problem known? What could I do? Best regards Ulf
