[Dovecot] Question about Maildir automatic cleanup.
by José Ildefonso Camargo Tolosa 07 May '08

07 May '08

Hi! I want to automatically delete old messages from one user's Maildir, and I was thinking on running something like this: find /home/user/Maildir/cur/ /home/user/Maildir/new/ -daystart -mtime +15 -delete but I'm not sure if by deleting messages "manually" I will break the dovecot.index* files. What do you think? Thanks! Ildefonso. ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

[Dovecot] 1.07 to 1.0.13 mail_extra_groups
by Mark Sapiro 06 May '08

06 May '08

I have just upgraded from 1.0.7 to 1.0.13. I read the comments in the example .conf file and it seemed what I needed to enable dotlock access to mailboxes in /var/spool/mail (writable by 'mail' group) was "mail_privileged_group = mail" so I removed the "mail_extra_groups = mail" that I had in 1.0.7 and added "mail_privileged_group = mail", but I got errors like the following: May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX: Internal error occurred. Refer to server log for more information. [2008-05-06 12:48:54] May 6 12:48:54 sbh16 dovecot: POP3(xxx): Couldn't open INBOX top=0/0, retr=0/0, del=0/0, size=0 May 6 12:48:54 sbh16 dovecot: pop3-login: Login: user=<xxx>, method=PLAIN, rip=72.52.113.36, lip=72.52.113.36, secured I then put "mail_extra_groups = mail" back in the configuration. This seems to have the effect of setting both "mail_privileged_group = mail" and "mail_access_groups = mail" as well as issuing "Warning: mail_extra_groups setting was often used insecurely so it is now deprecated, use mail_access_groups or mail_privileged_group instead" when dovecot is started. So my question is what do I need. I thought it would be just "mail_privileged_group = mail", but that doesn't work. Do I need both "mail_privileged_group = mail" and "mail_access_groups = mail" or just "mail_access_groups = mail". Also, are the comments describing these in the example .conf file correct, or are they reversed. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

When I login through squirrelmail every thing works fine . But when I login again from the same host as a different user with new browser session, the mailbox of the new user displays correctly but the first user session displays the inbox of the second user . ie if I have two https sessions from a single machine and login as two different users the inbox of the later user is displayed in both the sessions. I checked the logs of dovecot and the following is noticed dovecot: May 06 11:12:25 Info: imap-login: Login: user=<ath>, method=PLAIN, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured dovecot: May 06 11:12:25 Info: IMAP(ath): Disconnected: Logged out there are lots of messages for a single login .

[Dovecot] deliver custom maildir creation
by Steve Roemen 06 May '08

06 May '08

/ I'm testing a new setup of postfix using deliver to put the messages into the user's maildir, and am curious if there is a way to make deliver create custom maildirs when it delivers to a valid user without a maildir? Right now it only creates the inbox, I'd like it to create the .sent/ .Trash/ and .SPAM dirs. Is this possible? Thanks -------------------------------------- / /Steve Roemen// /

[Dovecot] Problem with quota.
by john.wall＠cky.se 06 May '08

Hi, Im having problem with quota with 1.0.rc17-1ubuntu2.3. Problem is that dovecot wont bounce when quota are exceeded. I have set my quota limit to 2MB and my test-box is 3MB. here is my config: dovecot.conf: #ssl_cert_file = /etc/pki/dovecot/certs/myserver.example.com.crt #ssl_key_file = /etc/pki/dovecot/private/myserver.example.com.key #ssl_ca_file = /etc/pki/dovecot/certs/ca-bundle.crt mail_location = maildir:/home/vmail/%d/%u first_valid_uid = 5000 last_valid_uid = 5000 maildir_copy_with_hardlinks = yes disable_plaintext_auth = no protocols = imap imaps pop3 pop3s protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = outlook-idle delay-newmail } protocol pop3 { mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota log_path = /var/log/dovecot-deliver.log info_log_path = /var/log/dovecot-deliver.log } auth default { # Having "login" also as a mechanism make sure outlook can use the auth smtpd as well # http://wiki.dovecot.org/Authentication/Mechanisms mechanisms = plain login passdb sql { args = /etc/dovecot/sql.conf } userdb sql { args = /etc/dovecot/sql.conf } userdb static { args = uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes } userdb prefetch { } user = nobody socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = vmail group = vmail } client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { quota = maildir:storage=1024:messages=1000 acl = vfile:/etc/dovecot/acls trash = /etc/dovecot/trash.conf } sql.conf: driver = mysql connect = host=localhost dbname=mdbv3 user=xxxx password=xxxx user_query = SELECT concat('/home/vmail/', maildir) as home, concat('maildir:/home/vmail/', maildir) as mail, 5000 AS uid, 5000 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1' password_query = SELECT username as user, password, concat('/home/vmail/', maildir) as userdb_home, concat('maildir:/home/vmail/', maildir) as userdb_mail, 5000 as userdb_uid, 5000 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1' Is this file even nessesary ?

If the user received new mail on the new system, say, around 200kb, and then he/she logs in, messages from the old system are copied. If he had 100Mb of mails (old system), and quota is 20Mb, only the 200kb are shown. Dovecot was not restarted. The problem was what you pointed out, maildirsize had to be deleted, then everything seems to be ok - getquotaroot indicates 100Mb + 200kb. > How badly wrong is the quota? Show me some example values of what they > are and what they're supposed to be? How do you calculate what the quota > is supposed to be? User has +100Mb, quota 20Mb, quota indicates 0 or just the new mail count (messages received on the new system). As you said, just delete maildirsize. >> Is it possible that the migration order (creating dirs in that way) >> is causing the quota usage to be shown wrong? > If all this is before the imap process is started, I don't see any > problems. >> Is it possible that the amount of messages and the size can be the >> cause? > No. >> How can I manually tell dovecot to recalculate the quota, after >> copying messages (when a user logs in, and didn't receive new mails on >> the new mail system, but had messages big enough to exceed the quota >> limit) from the old system? > Deleting maildirsize file recalculates the quota.

[Dovecot] imap fs quota (rpc) won't work?
by Adam McDougall 06 May '08

06 May '08

In the past I dabbled with the imap quota plugin with the fs backend because I wanted to report usage to my users (not limit them). At the time, the quota plugin would make dovecot crash when trying to write to a folder (I can bring up this report if needed). However, in a later beta of dovecot 1.1 I tried quota again but I cannot get it to report any results. I've been wanting to use fs:noenforcing but also tried just quota = fs to simplify. When I right click a folder stored in my homedir, thunderbird tells me 'the server does not support quotas' in the folder properties. What else can I do? Thanks!

[Dovecot] Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged
by David Jonas 06 May '08

06 May '08

Upon upgrading from 1.0.2 to 1.1rc4 I see this error for many of our users: Getting size of message UID=1 failed Couldn't init INBOX: Can't sync mailbox: Messages keep getting expunged Logging in with IMAP I would see a bunch of messages with no subject or time and blank bodies (usine horde/imp). Removing dovecot.index.log, dovecot.index.log.2, or dovecot-uidlist fixes the problem for the account (I chose dovecot.index.log). I imagine that forces a rebuild of the indexes. Removing other files in the directory didn't seem to make a difference, including dovecot.index or some arbitrary non-dovecot file. Is there a more conventional way around this problem?
