[Dovecot] Intermittent timeout issues
by Del Stoliker 01 Jun '10

01 Jun '10

Greetings list! We've been experiencing an intermittent issue in which none users are able to log into the mail server for about 10 to 20 minutes. This issue first appeared on our CentOS 4 box running dovecot 1.2.11 after upgrading from the stock version 0.99. The issue persists after migrating our users to a CentOS 5 server - also running version dovecot 1.2.11 but now in the 64-bit flavor. Our users authenticate against LDAP via PAM in case that might be relevant. I've yet to find anything "of interest" in the logs covering the outages. But here is what I've noticed: * Users on our internal network are still able to authenticate and login. * Users from the outside are "Disconnected for inactivity" * Immediately after the restart, external users were able to log in again. It almost sounds like the firewall is blocking external access except that: * The version of dovecot was the thing that changed * Everything starts working again after a dovecot restart If anyone could provide some insight, I'd sure appreciate it. Output of dovecot -n # 1.2.11: /etc/dovecot.conf # OS: Linux 2.6.18-164.15.1.el5 x86_64 CentOS release 5.4 (Final) listen: * shutdown_clients: no 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 login_process_per_connection: no login_trusted_networks: x.x.x.x/x login_max_processes_count: 164 max_mail_processes: 2048 mail_max_userip_connections: 50 mail_location: maildir:~/Maildir 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/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 pop3_no_flag_updates(default): no pop3_no_flag_updates(imap): no pop3_no_flag_updates(pop3): yes pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster(a)domain.com sendmail_path: /usr/sbin/sendmail auth default: passdb: driver: pam userdb: driver: passwd

[Dovecot] purge maildir folder after sa-learn
by Florian Effenberger 01 Jun '10

01 Jun '10

Hello, I am looking for a command-line utility to automatically purge one Maildir folder. I want to periodically run sa-learn from cron, and after the spam learning folder has been added to the Bayes database, its contents should be deleted. I've searched a bit, but only found a few old utilities or some telnet+expect scripts, which both didn't look too reliable. Is there any command-line utility to delete all contents of a Maildir folder, or is there any other solution? Thanks, Florian

Re: [Dovecot] cur folder e-mails are not shown...

>Since you didn't claim you actually are missing mail, just seeing more Nope. As I suffer the same problem from Evolution and ThunderBird >They could be "deleted" (actually marked for deletion, physically >removed upon expunge). Those would have a T flag in the file name after >the comma. Your MUA Evolution shows them in the Trash (virtual) folder. I tried all this but nothing shown. It's like cur folder is not shown. >They could have been flagged Junk, and only be displayed in the Junk >(virtual) folder. Junk folder is almost empty since I have SpamAsassin in place >You could have a search active, hiding some mail. I checked this also. But's not. >You could have specifically hidden them. See the View menu. I checked show all. But only a few appears. The one deleted by spam filter in the client. What else can be?

[Dovecot] RTFM: Manual pages for Dovecot v2.0
by Pascal Volk 01 Jun '10

01 Jun '10

Hello Dovecot admins. I've started writing manual pages for Dovecot v2.0. I'm sure they are not perfect yet. I'd like to ask you all to read the manual pages. It would be nice to get some ideas/suggestions/improvements. So that that the Dovecot v2.0.0 release could be distributed with /fine manuals/. The manual pages are available at: http://wiki2.dovecot.org/ManPages This is also the intended place for 'discussions' about the man pages. Regards, Pascal -- The trapper recommends today: cafebabe.1007713(a)localdomain.org
