[Dovecot] mdbox & trash
by Daniel L. Miller 09 Nov '10

09 Nov '10

Is there a way I can setup "trash" folders to be stored in a different subdirectory using mdbox? The goal is to provide a way to identify the trash folders for my backup solution (rsync) and avoid copying trash. -- Daniel

[Dovecot] how can I use different LDAP config for LDA and AUTH?
by Zhou, Yan 09 Nov '10

09 Nov '10

Hi there, I am setting up mail client with DoveCot and, at the same time, use Postfix to deliver message to DoveCot via LDA. I want to support having user name "jsmith" on my mail client, and that gets all messages for email address: dovecotdemo@domain. (The user name is different from what is in the email address). In addition, all user & password look up is handled by LDAP. Here is my problem: 1. my mail client will login as "jsmith", that goes through LDAP to find mail/home/password for this user. (this matches user name) 2. When postfix delivers a message, DoveCot LDA will find a match with email address "dovecotdemo@domain", it goes through the same LDAP configuration. (this matches email address). You can see the two search criteria are different, but by default they use the same passdb and userdb configuration. I want to use a different LDAP config. file for LDA to use, where it will match the email address (so that it is different from the default dovecot-ldap.conf, which is used by authentication). DoveCot Deliver can specify a separate configuration file with "-c", so I tried that. But I cannot get LDA to use a different configuration. Would should be an example of config file used by Deliver? Anyone running into this problem? Thanks, Yan NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

[Dovecot] 2.0, hourly performance stats
by Ralf Hildebrandt 08 Nov '10

I'm getting constantly high numbers of page reclaims & involuntary context switches for dovecot/auth. page reclaims = minor faults = cpu switching back to system-mode, But why is the auth process doing that so excessively? Same for the large number of involuntary context switches... Attached is my "dovecot -n" output.

[Dovecot] Expunge -A cannot find users
by Kilburn Abrahams 08 Nov '10

08 Nov '10

Hi List, If I use doveadm expunge in this format expunge will delete the email doveadm expunge -u test(a)planetseafood.com mailbox Archive ON '8-Nov-2010' But in this format doveadm expunge -A mailbox Archive ON '8-Nov-2010', it will list all the users in the database and display the following and no messages are expunged. doveadm(test@planetseafood.com@planetseafood.com): Info: User no longer exists, skipping. The iterate_query = SELECT username AS username, domain FROM mailbox which is correct for the DB layout. I am not using the expire plugin. Is this a permissions issue? Thanks Kilburn

[Dovecot] Estimación de horas del cambio a Dovecot 2.0
by Antonio Perez-Aranda 08 Nov '10

08 Nov '10

Actualmente tenemos dovecot 1.2.15 que ha demostrado ser bastante estable, pero con el que podemos tener problemas de corrupción en ficheros de índices de Dovecot (dovecot-uidlist). Este problema, podría llegar a ocasionar la descarga de todos los correos desde el cliente del usuario. En Dovecot 2.0 tenemos una mejor gestión sobre NFS mediante un nuevo sistema llamado director. Con este director se consigue que dovecot haga a su vez de proxy/balanceador e intente direccionar las conexiones de un usuario a un mismo servidor si este permite conexiones. En resumen, conseguimos evitar escrituras "concurrentes" sobre cachés de NFS que podrían ocasionar corrupción en determinados índices de dovecot. Para este cambio básicamente deberíamos repetir ciertas pruebas que hemos realizado para dovecot 1.2 así como ciertas tareas. 1. Actualizar configuración 2. Actualizar plugin TrataSPAM (MarcaSPAM/DesmarcaSPAM) Usando skel creado por Timo durante las sesiones de Málaga. 3. Pruebas de tiempos de indexado con SQUAT 4. Búsquedas concurrentes. 5. Pruebas de IMAP IDLE. 6. Migración { Keywords, suscriptions, flags, status...} 7. Condiciones de estrés. 8. Actualizar Doc. En una primera estimación. El total de estas tareas no debería superar las 45-50 horas. A cambio obtendríamos: 1. Un mejor soporte por parte de Timo. 2. doveadm para realizar búsquedas, gestión del director, pruebas de depuración... 3. Mejoras en el comportamiento ante storage en NFS. 4. Mejoras en la coordinación con SOLR para cuando comencemos con el buscador avanzado con ficheros adjuntos. 5. Mejoras para conexiones concurrentes. La razón por la que no empezamos directamente con dovecot 2.0 es porque no preveíamos que fuera relativamente estable en poco tiempo. Observando la lista de correos y después de la conversación con Timo, la última release de dovecot 2.0 es lo suficientemente estable como para usarse en sistemas de producción. Si lo creéis necesario, podemos organizar una reunión para tomar la decisión, aunque sí que esta reunión debería ser para esta semana o a principios de la siguiente.

Summarising mail standards (WRT headers) There is a limit of 4096 characters per line. If Outlook is breaking at less than that it's a bug. If the References: line is longer than that then it should have been truncated by the sending MUA - there's no provision for multiline References headers (which are a non-standardised import from Usenet anyway).

[Dovecot] Last login tracking with login_executable
by Denny Lin 07 Nov '10

07 Nov '10

Hi, I'm using Dovecot 1.2.14, and I've read PostLoginScripting on the wiki. Is there any way to make Dovecot use the same username/password for database access as userdb and passdb queries? Specifying the password with -p doesn't seem like a good idea, so I'm wondering if it can be handled by Dovecot directly. Or is it possible to track last logins with a plugin similar to quota? -- Denny Lin
