[Dovecot] dict ldap
by me＠electronico.nc 14 Jan '14

Hello everybody, Dovecot 2.2.6 with LDAP auth against AD (Samba4). I would like to know if it's possible to specify an LDAP transport for dict (something like dovecot-dict-ldap.conf.ext). I'm in need to setup shared mailboxes and if I could query LDAP, that would help a lot. IE : user1 user2 user3 are in OU=group1, so group1 (setup as user in AD) would share its mailbox with user1 user2 and user3. Thanks in advance for your time. Nicolas

[Dovecot] Slow authentication performance when switching folder
by ra＠rz.uni-frankfurt.de 13 Jan '14

Hello, we have a problem with Dovecot 2.2.9 running on an AIX 7.1 and compiled with xlc. At first we configured passdb to use our ldap directory via pam and experienced an Internal login failure like the following one Jan 13 16:20:02 imap-login: Info: Internal login failure (pid=29818948 id=1) (internal failure, 1 successful auths): user=<user>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=yyy.yyy.yyy.yyy, TLS, session=<r/P1m9vv5ACNAv6j> I read that this error occurs if the last passdb returns a continue and there is no other passdb to ask. We added two more passdb to rule out that pam is the problem. We added ldap directly and as third a fallback passwd file, but we still get the Internal login failure. As far as i can see this only occurs if i switch to another folder and i´m being reauthenticated. Are there any suggestions on what is going wrong? Any push in the right direction would be appreciated. kind regards Manuel PS: This is the dump of our dovecot configuration file: doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (32768) doveconf: Warning: service anvil { client_limit=1000 } is lower than required under max. load (24579) # OS: AIX 1 00F7B83D4C00 auth_debug = yes auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890- auth_username_format = %n auth_username_translation = AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvWwXxYyZz auth_verbose = yes base_dir = /var/run/dovecot-imap default_process_limit = 8192 disable_plaintext_auth = no first_valid_uid = 100 info_log_path = /mailbase/dovecot/2.2.9/log/dovecot_imap_debug.log log_path = /mailbase/dovecot/2.2.9/log/dovecot_imap.log login_greeting = University-Frankfurt-IMAP-Horde ready. mail_access_groups = mhs mail_debug = yes mail_fsync = never mail_location = mbox:~/:INBOX=/var/spool/mail/%u:INDEX=/var/mail-indexes/%u mailbox_idle_check_interval = 90 secs mbox_write_locks = fcntl namespace { inbox = yes location = prefix = separator = / type = private name = } passdb { args = username_format=%u /mailbase/etc/passwd driver = passwd-file } passdb { args = %s driver = pam } plugin { stats_refresh = 30 secs stats_track_cmds = yes } service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service { inet_listener { address = * port = 0 name = imap } inet_listener { address = * port = 993 name = imaps } name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service { inet_listener { address = 10.1.1.40 port = 0 name = pop3 } inet_listener { address = * port = 0 name = pop3s } name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } ssl_cert = </etc/ssl/certs/thot_mit_chain.crt ssl_key = </etc/ssl/certs/private_key_thot.rz.pem userdb { driver = passwd } userdb { args = /mailbase/dovecot/2.2.9/etc/dovecot/dovecot-ldap.conf driver = ldap } protocol imap { mail_plugins = " stats imap_stats" service replication-notify-fifo { name = aggregator } service anvil-auth-penalty { name = anvil } service auth-worker { name = auth-worker } service auth-client { name = auth } service config { name = config } service dict { name = dict } service login/proxy-notify { name = director } service dns-client { name = dns_client } service doveadm-server { name = doveadm } service imap { name = imap-login } service imap-urlauth { name = imap-urlauth-login } service imap-urlauth-worker { name = imap-urlauth-worker } service token-login/imap-urlauth { name = imap-urlauth } service login/imap { name = imap } service indexer-worker { name = indexer-worker } service indexer { name = indexer } service ipc { name = ipc } service lmtp { name = lmtp } service log-errors { name = log } service pop3 { name = pop3-login } service login/pop3 { name = pop3 } service replicator-doveadm { name = replicator } service login/ssl-params { name = ssl-params } service stats-mail { name = stats } }

it's possible to send email from the system after the mailbox quota is full i don't want warning mail i want something else because when i use warning on 100% or 99% or less some times the last message be too large (so if just 5% is free from quota size and the last msg size is 6% from quota ) after that the mailbox will not receive this message or warning message . -- View this message in context: http://dovecot.2317879.n4.nabble.com/it-s-possible-to-send-email-from-the-s… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] dsync error: gz trailer has wrong CRC value
by Joe Beaubien 13 Jan '14

13 Jan '14

A few days ago by dovecot installation started behaving weirdly. First it was doveadm fts optimize which would fail (a thread running about that) and now it's dsync, which means my backups are not working. This all started a few days ago, which I find a little weird, because I haven't messed around with the dovecot setup in months. I've been searching the internet, but didn't find anything useful yet. Would anyone know how to fix the errors in the log below? Thanks, -Joe dovecot version is 2.1.7 Here is the log: dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): gz trailer has wrong CRC value at 16966298 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: read(msg input) failed: Invalid argument dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Panic: file mail-index-transaction-update.c: line 906 (mail_index_update_ext): assertion failed: (seq > 0 && (seq <= mail_index_view_get_messages_count(t->view) || seq <= t->last_new_seq)) dsync(archive): Error: Raw backtrace: /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(+0x4203a) [0x7f3a5150503a] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f3a515050fa] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f3a514dc3f0] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_index_update_ext+0x1c7) [0x7f3a51804927] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa8746) [0x7f3a517f7746] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_cache_transaction_commit+0x4c) [0x7f3a517f7a2c] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa8af3) [0x7f3a517f7af3] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa2cea) [0x7f3a517f1cea] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0x84) [0x7f3a51800754] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x8a) [0x7f3a517f209a] -> /opt/dovec ot/lib/d ovecot/lib20_zlib_plugin.so(+0x3b7a) [0x7f3a4fe8cb7a] -> /opt/dovecot/lib/dovecot/lib20_fts_plugin.so(+0xb481) [0x7f3a5009b481] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_changes+0x3d) [0x7f3a517c9c4d] -> /opt/dovecot/bin/dsync() [0x4297e6] -> /opt/dovecot/bin/dsync() [0x42b222] -> /opt/dovecot/bin/dsync(dsync_worker_select_mailbox+0x2e) [0x4291be] -> /opt/dovecot/bin/dsync() [0x424c75] -> /opt/dovecot/bin/dsync() [0x424db7] -> /opt/dovecot/bin/dsync(dsync_brain_msg_sync_more+0x22c) [0x4245ec] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x459) [0x422fc9] -> /opt/dovecot/bin/dsync() [0x423e61] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x7f1) [0x423361] -> /opt/dovecot/bin/dsync() [0x423cdc] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x832) [0x4233a2] -> /opt/dovecot/bin/dsync(dsync_brain_sync_all+0x18) [0x423ee8] -> /opt/dovecot/bin/dsync() [0x420f36] -> /opt/dovecot/bin/dsync() [0x4215b2] -> /opt/dovecot/bin/dsync() [0x40e798]
