[Dovecot] Logging subjects of messages
by Sandu cucereanu 07 Jul '10

07 Jul '10

Dear Sirs, I want to know if there is any possibility to log the subjects of the messages downloaded from ther server. We use dovecot 1.0.15 with POP3S and IMAP and we want to keep a trace of the reading of messages by the users of our mail server (who, when and what are the subjects of the e-mail messages read) because some users complain that they did not read some messages but in the logs of the server (maillog files( those messages appear to be delivered to their inboxes. Thank you very much for your help Best regards Alexandru Cucereanu

Hello, by accident I had configured inside 15-lda.conf protocol lda { mail_plugins = autocreate imap_acl acl } (I only wanted autocreate sieve.) There ist a problem with the symbol hook_client_created: lda: Error: dlopen(/usr/dovecot-2.0.rc1/lib/dovecot/lib02_imap_acl_plugin.so) failed: ld.so.1: dovecot-lda: fatal: relocation error: file /usr/dovecot-2.0.rc1/lib/dovecot/lib02_imap_acl_ lugin.so: symbol hook_client_created: referenced symbol not found lda: Fatal: Couldn't load required plugins ) -- Burckhard Schmidt

[Dovecot] dsync convert Maildir -> mdbox, separators in subscriptions file
by Frode Nordahl 06 Jul '10

06 Jul '10

Hello, I'm playing around with Dovecot 2.0 beta 4. If I use dsync to convert a users mail stored in Maildir format to mdbox format, the subscriptions file in the new mdbox is created using the wrong mailbox separator ('.') leading to folders within folders not being readable by clients using the subscription feature. Excerpt from IMAP: . LIST "" "*" * LIST (\HasChildren) "/" "Spam" * LIST (\HasNoChildren) "/" "Spam/Test" . LSUB "" "*" * LSUB () "/" "Spam" * LSUB () "/" "Spam.Test" I am not currently using Maildir, and have no plans to either, so I am very pleased with mdbox using '/' as seperator. I am considering to use Maildir as a transition format so that I can use allready available scripts to do the job (uw2dovecot.pl first, then dsync). So the question is, is this a bug in dsync? At the time of conversion mail_location = maildir:~/Maildir I used the following command to do the conversion: # dsync -u username convert mdbox:~/mdbox -- Frode Nordahl

[Dovecot] how to setup a simplest travel-mode read-only IMAP
by Seetamraju Uday Bhaskar Sarma 06 Jul '10

06 Jul '10

Hi All, I don't use gmail/hotmail etc... I have been a Mozilla/SeaMonkey/Thunderbird user for ever now... The mail and folders are all on my private fileserver. But on certain tours, I do know in advance that I would like IMAP access to my mail folders. Nothing but the simplest read-only access to the years of accumulated email. (All that email was soft-mounted onto /mnt/mail for safety and simplicity.) I have read the FAQ and Wiki. I even created the /cur /new /tmp folders under /mnt/mail... (after noting errors in dovecot logs) But when I test from another machine as :- # mutt -f imap://sarma@10.0.1.10/Inbox mutt comes up blank. I did check that /mnt/mail/Inbox exists, and has read permissions to all. Ideally, I don't want dovecot updating my mail files. I just simply want to read my old mail, while my new mail will continue to reside-on/be-accessible via the webmail. Thanks in advance! # /usr/sbin/dovecot --version 1.0.15 # /usr/sbin/dovecot -n # 1.0.15: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 1 login_max_processes_count: 2 mail_privileged_group: mail mail_location: maildir:/mnt/mail:INDEX=/var/mail/dovecot/index:CONTROL=/var/mail/dovecot/lib:LAYOUT=fs mbox_dirty_syncs: no mbox_lazy_writes: no auth default: passdb: driver: pam userdb: driver: passwd

[Dovecot] Correct folder permissions for maildir....
by Donovan J. Edye 06 Jul '10

06 Jul '10

G'Day, I am trying to find a definitive answer to what the directory permissions should be for my configuration under Centos 5.5. I see a number of the following error messages in the maillog as a consequence of permissions errors. After reading the FAQ, Wiki etc. and browsing the web I am unable to determine just exactly what the user security settings should be for the offending folders. If anyone could point me in the right direction I would appreciate it. Should you require additional diagnostic information let me know and I will source it.

[Dovecot] ACL, forced INBOX subscription
by Matthias Rieber 06 Jul '10

06 Jul '10

Hi, I've two accounts 'matthias' and 'mailverwalter'. Mailverwalter want's to share the Spam folder: This is the situation in the beginning: (matthias) a LIST (SUBSCRIBED) "common." "*" a OK List completed. a LIST (SUBSCRIBED) "common.mailverwalter" "*" a OK List completed. (mailverwalter) a GETACL Spam * ACL "Spam" "mailverwalter" lrwstipekxacd a OK Getacl completed. a GETACL INBOX * ACL "INBOX" "mailverwalter" lrwstipekxacd a OK Getacl completed. So far so good. Mailverwalter sets the list permission: (mailverwalter) a SETACL "Spam" "matthias" l a OK Setacl complete. a GETACL "Spam" * ACL "Spam" "matthias" l "mailverwalter" lrwstipekxacd a OK Getacl completed. a GETACL "INBOX" * ACL "INBOX" "mailverwalter" lrwstipekxacd a OK Getacl completed. That's ok as well and I want to make sure that the INBOX doesn't have any other permission. After that, some listing: (matthias) a LIST (SUBSCRIBED) "common." "*" a OK List completed. a LIST (SUBSCRIBED) "common.mailverwalter." "*" a OK List completed. That's also ok, nothing subscribed. (matthias) a LIST "common.mailverwalter." "*" * LIST (\Noselect \HasChildren) "." "common.mailverwalter" * LIST (\HasNoChildren) "." "common.mailverwalter.Spam" a OK List completed. This normal folder listing seems to be ok, too, and then listing of the subcribed folders again: (matthias) a LIST (SUBSCRIBED) "common.mailverwalter." "*" * LIST (\Subscribed \NonExistent) "." "common.mailverwalter.INBOX" a OK List completed. And then, the INBOX is subscribed and \NonExistent because I don't have permissions on it. The folder stays subscribed as long as I'm connected to the server. When I disconnect and do the LIST (SUBSCRIBED) again, the folder is not subscribed as long I do not 'normal' list it. Happens with dovecot 1.2.11, haven't tried 2.0 yet. I assume that's not the intended behaviour. This INBOX folder confuses the Nokia n900 email client a lot, but it doesn't matter if it can be accessed or not. Regards, Matthias

[Dovecot] Jul 06 13:00:50 dovecot: Warning: I/O leak: 806ef10 (36)
by Dennis Clarke 06 Jul '10

06 Jul '10

I'm currently fighting my way through the dovecot configuration pages and endless options to see if I can just get my mail from the server. Thus far no joy but dovecot seems to be working if I could figure out the configuration. My process thus far has been : 1) read docs 2) try a config change 3) fail 4) goto (1) I just saw an error while trying to read my /var/mail/dclarke good 'ol mbox in the message.log : Jul 06 12:58:50 IMAP(dclarke): Error: mbox root directory can't be a file: /var/mail/dclarke/ (http://wiki.dovecot.org/MailLocation/Mbox) So I figure I better go read that page again and see what I did wrong this time. I guess this is wrong : mail_location: mbox:/var/mail/%u Even though that is where the mail actually is : # ls -lap /var/mail total 34 drwxrwxrwt 3 root mail 6 Jul 6 02:19 ./ drwxr-xr-x 47 root sys 47 May 30 02:52 ../ drwxrwxr-x 2 root mail 2 May 29 23:47 :saved/ -rw-rw---- 1 dclarke mail 0 Jul 5 16:01 dclarke -rw-rw---- 1 lucone mail 657 Jul 2 17:55 lucone -rw-rw---- 1 root mail 8705 Jul 2 05:40 root # I shutdown the dovecot service on Solaris via svcadm and saw this in the error log : Jul 06 13:00:50 dovecot: Warning: I/O leak: 806ef10 (36) Jul 06 13:00:50 dovecot: Warning: I/O leak: 806ef10 (30) Jul 06 13:00:50 dovecot: Warning: I/O leak: 806ef10 (26) Jul 06 13:00:50 dovecot: Warning: I/O leak: 806ef10 (24) I'm not too sure what that means but it doesn't look good.

[Dovecot] Multiple authentication backends
by Wouter van der Schagt 06 Jul '10

06 Jul '10

Good morning, I have a question. Currently we are using Dovecot to handle our pop3, pop3s, imap and imaps connections. Our virtual domain management backend is vpopmail. Which works beautifully. Our current setup requires users to login with their email address and password (user@domain). We are now looking at migrating another server to our environment where users are logging in with their username only. This is because unlike virtual users these mailboxes have corresponding system users on the server. Ideally we would like to migration for the end user as easy as possible without requiring them to make changes to their settings. Is it possible to configure Dovecot to handle multiple authentication back-ends or do any of you have found a solution to a similar problem before? Sincerely, - Wouter van der Schagt
