[Dovecot] permissions on auth-userdb Error: userdb lookup

Hello, first sorry for this question. I already found many threads about this problem including a thread in this list from August 2010, but nothing helped :( Here is the error: 2010-09-20 06:28:04 lda: Debug: Loading modules from directory: /usr/lib/dovecot/modules/ 2010-09-20 06:28:04 lda: Debug: Module loaded: /usr/lib/dovecot/modules//lib90_sieve_plugin.so 2010-09-20 06:28:04 lda: Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +r perm: /var/run/dovecot/auth-userdb, euid is not dir owner) 2010-09-20 06:28:04 lda: Fatal: Internal error occurred.

[Dovecot] dovecot-2.0.3 - can not upload message, over quota
by LEVAI Daniel 20 Sep '10

20 Sep '10

Hi! I've upgraded to 2.0.3 from 1.2, and it is so far so good. I especially like the new doveadm tool. I have only one tiny problem: Every time I try to upload a message to the server (eg. to a 'Sent' folder, while sending a message), it fails with an error saying I'm over my quota. I'm using mutt, and this is the exact message I get in mutt: [OVERQUOTA] Quota exceeded (mailbox for user is full) Now this is not true, because dovecot-lda can save message to any of my folders, and doveadm says I have no quota (which is true): # doveadm quota get -u <user> Quota name Type Value Limit % User quota STORAGE 1075010 - 0 User quota MESSAGE 26750 - 0 Dovecot logs say nothing about this. Why is that error message then? (I must admit that I didn't try with another mail client.) I've tried to recalc the quota with doveadm but no luck. doveconf -n: # 2.0.3: /etc/dovecot/dovecot.conf # OS: OpenBSD 4.7 i386 default_internal_user = _dovecot default_login_user = _dovenull dict { expire = pgsql:/etc/dovecot/dovecot-sql.conf } info_log_path = /var/log/mail/dovecot.info listen = 127.0.0.1 log_path = /var/log/mail/dovecot.log mail_location = maildir:~/Maildir/ mail_plugins = quota expire passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { expire = sa.* 1 expire_dict = proxy::expire quota = maildir:User quota quota_rule = *:storage=100M quota_rule2 = Trash:storage=+50M } protocols = pop3 imap userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota } protocol pop3 { mail_plugins = $mail_plugins pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv } protocol lda { deliver_log_format = msgid=%m, from=%f, subject=%s: %$ mail_plugins = $mail_plugins sieve sendmail_path = /usr/local/sbin/sendmail } TIA, Daniel -- LÉVAI Dániel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F

[Dovecot] v2.0.3 released
by Timo Sirainen 20 Sep '10

20 Sep '10

http://dovecot.org/releases/2.0/dovecot-2.0.3.tar.gz http://dovecot.org/releases/2.0/dovecot-2.0.3.tar.gz.sig * dovecot-lda: Removed use of non-standard Envelope-To: header as a default for -a. Set lda_original_recipient_header=Envelope-To to returns the old behavior. + Added support for reverse quota warnings (i.e. when quota goes back under the limit). This is enabled by adding '-' to beginning of quota_warning value. Based on patch by Jeroen Koekkoek. + dovecot-lda: Added lda_original_recipient_header setting, which is used for getting original recipient if -a isn't used. + dovecot-lda: Added -r parameter to specify final recipient address. (It may differ from original address for e.g. aliases.) + Maildir: uidlist file can now override message's GUID, making it possible for multiple messages in a mailbox to have the same GUID. This also fixes dsync's message conflict resolution. - dovecot-lda: If destination user isn't found, exit with EX_NOUSER, not EX_TEMPFAIL. - dsync: Fixed handling \Noselect mailboxes - Fixed an infinite loop introduced by v2.0.2's message parser changes. - Fixed a crash introduced by v2.0.2's istream-crlf changes.

[Dovecot] replace istream and unref the old one...
by Alex Baule 20 Sep '10

20 Sep '10

I Build a plugin, that do some stuffs with a email. To get the input istream, i use the "get_stream" function, like zlib does. I create a concat_stream, with the full_input[3]; struct istream *full_input[3]; //this like zlib input = imail->data.stream; //first input, using the input full_input[0] = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, exclude_headers, 1, filter_callback, imail); // second input from another file. full_input[1] = i_stream_create_fd(fd1, 0, TRUE); // finish the input full_input[2] = NULL; // recreating the stream imail->data.stream = i_stream_create_concat(full_input); //unref the old one. i_stream_unref(&input); return index_mail_init_stream(imail, hdr_size, body_size, stream_r); I do like zlib, but i got this errors in LOG. I Think it's because something in the unref, but o don't know what.

[Dovecot] Dovecot 2.0.3
by Matthias Quernheim 20 Sep '10

20 Sep '10

I upgraded today to from 1.2.12 to Dovecot 2.0.3 with the dbox format. I just figured out there are still mail in some users directories with the maildir format. These mail are not displayed at all. Nether with roundcube nor with Thunderbird. How could I convert the remaining maildir mails to dbox? Thanks Matthias

[Dovecot] send HUP when rotating log?
by LEVAI Daniel 20 Sep '10

20 Sep '10

Hi! Is it necessary for Dovecot2 to send it a SIGHUP when I rotate its log files? I'm asking because then I must turn off the 'shutdown_clients' option, because then every user gets disconnected while rotating the logs.

[Dovecot] Change in delivery directory during 2.0.2->2.0.3 upgrade
by Jeffrey Rice 19 Sep '10

19 Sep '10

In upgrading from 2.0.2 to 2.0.3, Dovecot deliver has started putting new emails into user@host/.user@host/new instead of user@host/new. This change was reversed by downgrading to 2.0.2, so it's due to the minor version change. Has anyone else seen this? dovecot.conf follows: # 2.0.0: /etc/dovecot/dovecot.conf # OS: Linux 2.6.27.2-xenU i686 Debian 5.0.5 ext3 auth_mechanisms = plain cram-md5 login digest-md5 dotlock_use_excl = yes login_greeting = IMAP ready. mail_fsync = never mail_location = maildir:/home/vmail/%u passdb { args = /etc/dovecot/dovecot-mysql.cnf driver = sql } plugin { auth_socket_path = /var/run/dovecot/auth-master sieve_global_path = /home/vmail/sieve/global.sieve } service auth { unix_listener /var/run/dovecot/auth-master { group = vmail mode = 0600 user = vmail } unix_listener /var/spool/postfix/private/dovecot-auth-client { group = postfix mode = 0660 user = postfix } user = root } service imap-login { client_limit = 256 process_limit = 128 process_min_avail = 4 service_count = 0 user = dovecot } service imap { vsz_limit = 70 } service pop3-login { client_limit = 256 process_limit = 128 process_min_avail = 4 service_count = 0 user = dovecot } service pop3 { vsz_limit = 70 } ssl_cert = </etc/dovecot/ssl/certs/dovecot_cert.pem ssl_cipher_list = ALL:!LOW ssl_key = </etc/dovecot/ssl/private/dovecot_key.pem userdb { driver = passwd } userdb { args = uid=5000 gid=5000 home=/home/vmail/%u driver = static } protocol imap { mail_plugin_dir = /usr/local/lib/dovecot/imap mail_plugins = } protocol lda { auth_socket_path = /var/run/dovecot/auth-master info_log_path = /home/vmail/dovecot-deliver.log log_path = /home/vmail/dovecot-deliver.log mail_plugins = sieve postmaster_address = postmaster(a)finity.org } deliver is invoked in postfix's master.cf using: dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient} -- Jeffrey Rice<jeffrice(a)finity.org>

[Dovecot] mbox vs maildir
by Jim Pazarena 18 Sep '10

18 Sep '10

I've had clients 'request' nested folders, and it would seem that maildir is designed with that ability while with mbox it is difficult and.or impossible to implement (nested can be achieved; but not nested AND populated in each nest level). My question is, is one format 'better' than the other? It would take a fair bit of time to convert my system to maildir and I would want to feel comfortable that this would be a true 'upgrade' in abilities, rather than simply a change to accommodate nested folders. Thanks,

[Dovecot] moving 1.2.13 system to another hard drive
by Paul Scott 18 Sep '10

18 Sep '10

Hi, I am not very experienced with Dovecot (1,2,13) installed on Debian sid. I have just set up a new system on a new hard drive on the same computer. fetchmail is correctly putting mail in /var/mail/<username>. I have copied my entire Maildir directory from the old hard drive. I have made what changes I understood to dovecot.conf. Dovecot was working on the other drive even though I'm not completely sure how I got it working before. Any ideas for debugging this certainly simple problem for some of you. TIA, Paul Scott
