[Dovecot] v1.2: Can't subscribe to shared user folder
by Sascha Wilde 12 Feb '09

12 Feb '09

Hi *, I stumbled across a small bug (missing feature?) in the new shared name space stuff: a001 list "" "*" * LIST (\Noselect \HasChildren) "/" "user" * LIST (\Noselect \HasChildren) "/" "user/bob(a)example.com" * LIST (\HasChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "INBOX/bar" * LIST (\HasNoChildren) "/" "user/bob(a)example.com/brooklebookle" * LIST (\HasNoChildren) "/" "user/bob(a)example.com/foobar" a001 OK List completed. a002 lsub "" "*" a002 OK Lsub completed. a003 subscribe "user/bob(a)example.com/foobar" a003 NO Unknown subscription namespace. I'm quite sure this once worked in our original code (but of cause I could be mistaken). cheers sascha -- Sascha Wilde OpenPGP key: 4BB86568 http://www.intevation.de/~wilde/ http://www.intevation.de/ Intevation GmbH, Neuer Graben 17, 49074 Osnabrück; AG Osnabrück, HR B 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner

[Dovecot] (Somewhat urgent) Problem with maildir++ quota
by Santiago Romero 12 Feb '09

12 Feb '09

Hi. I have an strange problem with dovecot's maildir quota and postfix. I've tested quota and it works fine but sometimes there are users that having their Maildir/ empty, they trigger the "quota exceeded" message when someone sends email to them. Some config / version info: ### Versions: ii dovecot-common 1:1.0.10-1ubuntu5.1 ii dovecot-imapd 1:1.0.10-1ubuntu5.1 ii dovecot-pop3d 1:1.0.10-1ubuntu5.1 ### From dovecot.conf: (...) # SQL database <doc/wiki/AuthDatabase.SQL.txt> userdb sql { # Path for SQL configuration file args = /etc/dovecot/dovecot-mysql.conf } (...) dict { #quota = mysql:/etc/dovecot-dict-quota.conf } (...) plugin { quota = maildir:storage=51200 } ### dovecot-mysql.conf (splitted to be readable): user_query = SELECT maildir, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', floor(quota/1024)) AS quota FROM mailbox WHERE username = '%u' AND active = '1' ### Database "mailbox" record example: | prueba(a)domain.com | Password | prueba | domain.com/prueba/ | 51200000 | domain.com | 2009-02-02 10:01:24 | 2009-02-02 10:07:46 | 1 | The symptons: users are working nicely, and quota works (If I create a new user and set it a quota of, say, 1MB, I can send him msgs until Maildir reachs 1MB, after that I get "quota exceeded" messages). But sometimes there are users with the Maildir empty that can't receive messages and trigger the "quota exceeded" warning. Users always download messages by POP. Removing "maildirsize" file in their folder fixes the problem. Also fixes it changing the quota to any value (maildirsize is then removed and recreated after a new message arrives for the user). Sometime that I don't know if it's strange is that I don't see "removing" messages in the maildirsize file after user downloads messages. I mean that I can't see "-1" lines in maildirsizes: # cat prueba/maildirsize 51200000S 0 0 615 1 1540 1 11446 1 46085 1 2623 1 21218 1 2815301 1 15110 1 21289 1 18330 1 (and so). Any idea of what's going on? Shouldn't appear "MSGSIZE -1" lines in maildirsize file to "restore" space in Maildir after POP RETRs? Currently I'm fixing the problem with a regular: # find /home/vmail/vhosts -name "maildirsize" -exec rm {} \; But there must exist a better solution (or maybe my config is wrong). Thanks a lot for any help. -- Santiago Romero

[Dovecot] Panic in dovecot 1.2.beta1
by Mark Sapiro 11 Feb '09

11 Feb '09

I tried Dovecot 1.2.beta1 yesterday. I had been using 1.1.11. I started getting "Panic: POP3(xxx): Trying to allocate 0 bytes" There are two kinds of pop3 users. In the attached log.txt file, user u1 is using a pop3 MUA. For users u2, u3, u4 and u5 fetchmail is coming through an ssh tunnel and retrieving their mail. u1 is able to interact normally with dovecot, but the fetchmail users encountered the panics in the log. dovecot -n is attached as dovecot-n.txt. At first I thought it was a locking issue as .lock files were being left behind, so I changed pop3_lock_session to no, and restarted dovecot, but this didn't help so I reverted to 2.1.11. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] Adding new storage
by Romer Ventura 11 Feb '09

11 Feb '09

Hello, I am about to add more storage to the mail server and would like to know if it is as simple as it sounds..? I have: dovecot.conf mail_location: maildir:~/Maildir/ and /etc/dovecot/dovecot-ldap.conf with: user_attrs = sAMAccountName=mail=maildir:/home/vmail/%Ud/%Ln/Maildir/ So all the mail gets stored at /home/vmail/%Ud/%Ln/Maildir/ so if i add a new volume to the VM lets say /dev/disk3 and mount it to /srv/ vmail and then change the user_attrs = sAMAccountName=mail=maildir:/ home/vmail/%Ud/%Ln/Maildir/ to user_attrs = sAMAccountName=mail=maildir:/srv/vmail/%Ud/%Ln/Maildir/ would it work with no problem..? I would also need to move all the mailboxes already in the old location... I just want to make sure before i do anything.. Thanks

[Dovecot] Understanding dovecot ACLs
by Achim Hut 11 Feb '09

11 Feb '09

Hello List I am running a Cyrus IMAP that needs to be replaced. Geting a Dovecot IMAP up and running was surprisingly simple. My configuration is close to Johnny Chaddas Howto at http://johnny.chadda.se/2007/04/15/mail-server-howto-postfix-and-dovecot-wi… Its a Dovecot 1.1.10 on FreeBSD 6.4 Anyway, while basic setup was easy, i stuck in a couple of details like quota, managesieve, etc. Actual major problem and showstoper is understanding the ACLs the confuses me. So i need a hint to be guided in the right direction. What i need is a scenario, where user1 can get (for example) full access to the folders of user2, read-only access to user3 etc. A real world example: Secretary has full access to the mailfolders of her boss, boss has read-only acces to the sales-department folder. My questions: 1) is the possible? 2) can it be done with dovecot-acl files? 3) Namespaces: is it enough to have the private namespace for the job or do i need another namespace? 4) if yes, how should this namespace look like? Thanks for the help Achim

[Dovecot] dovecot logs to audit.log not to maillog
by Ralf Heidenreich 11 Feb '09

11 Feb '09

Hello, I have a curious phenomenon. Dovecot logs normally to /var/log/maillog. If I restart my server, dovecot loggs to /var/log/audit/audit.log. If I restart dovecot, dovecot loggs to /var/log/maillog again. And I think, wenn logrotate is restarting, dovecot logs to audit.log. But I don't know why. Any Ideas? greetings Ralf

[Dovecot] mailing lists and Dovecot deliver (lda)
by Roderick A. Anderson 11 Feb '09

11 Feb '09

I'm trying to figure out a way, or if it is even possible, to use mailing list software (majordomo2) on a Postfix + Dovecot + virtual mailboxes system. And where I should be looking. The examples on the Postfix site don't seem to address a purely virtual mailboxes system and I haven't found anything about doing it with deliver. I think I'm at the wrong tree (Dovecot deliver) and should be pestering the Postfix list. FTR, I host some sites for not-for-profits and they have asked about setting up lists. So far I've dodged the question but would like to attempt it now. Thanks, Rod --
