[Dovecot] pop3 connections hanging
Hi,
dovecot --version 1.0.beta8
dovecot -n login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: passdb: driver: pam userdb: driver: passwd
It is running with sendmail-8.13.5-3 on FC5 2.6.15-1.2054_FC5
I find that occasionally a pop3 connection will just sit there for hours on end. It will not release the lock on the user mailbox and so mail to that user cannot be delivered. As a result the mailq backs up mostly with mail to that user. Closing the MUA does not help. I have to kill -9 PID the process to clear the hung connection. This happens with both Outlook and Thunderbird.
Is there an option in the dovecot configuration that I can set to automatically close connections after say 30 minutes ?
In the workaround section it says that it will close connections from Outlook & Outlook Express after 30 minutes dues to an IDLE bug in those 2.
Regards,
Arjun Datta

The usual answer you will get is to upgrade to at least 1.0.0 stable, since older versions don't get any support. 1.0.0 has options for helping Outlook and others that don't behave well in idle.

Thanks Scott,
I like the suggestion but I am a little worried about upgrading with minimum fuss. Can I just install the latest version by stopping dovecot, installing the new version and restarting ?
I checked on the main webpage and under 1.0.2 there does not seem to be any .rpms available so is my only choice the tarball ?

What OS are you on? There are rpm's available for the RHEL line and clones, so you should be able to find something.

One machine is FC5: 2.6.15-1.2054_FC5 The other is FC6: 2.6.20-1.2948.fc6

I think there were some minor changes in syntax since beta8, so after you install the rpm, find the "/etc/dovecot.conf.rpmnew" file and use it as a model. Transfer your old settings into it and then rename it to "dovecot.conf". Then start dovecot.
