[Dovecot] Dovecot service not responding after about a week of uptime
by Matthieu 15 Jan '14

15 Jan '14

Hello, I am running a dovecot 2.1.13 server and lately it stops responding after about a week of uptime. Simply restarting the dovecot service solves the issue. I tried to look a bit in my maillog file but did not find anything obvious. During the time when the server is not responding I can still see imap-login entries from the connection attempt by my email client. Any help about how to diagnose the problem would be appreciated. Thanks, Matthieu

[Dovecot] Dovecot LMTP does not pass envelope recipient +detail to sieve
by Greg Rivers 14 Jan '14

14 Jan '14

I found this[1] thread that describes the same problem with dovecot-LDA, but the solution (add X-Original-To: header) has no effect with LMTP. My sendmail LMTP configuration: FEATURE(`local_lmtp',`[IPC]',`FILE /var/run/dovecot/lmtp') Sendmail's address test indicates that sendmail is providing user+detail to LMTP (see below). Except for this problem, dovecot, LMTP, and sieve are all working perfectly. Is there something I'm missing, or is this a bug?

[Dovecot] Sieve - not functioning for additional email aliases.
by Jacek Osiecki 14 Jan '14

14 Jan '14

Hi, On one of my servers (old one, version 1.2.5) user reported that vacation message for basic address works fine, but not for the aliases. I know that this is an old version, but we can't simply switch them to the most current dovecot release without preparing and testing everything... So I'm rather asking for help with debugging the case :) This person has email my.name(a)olddomain.pl. However, they are switching to new domain - newdomain.pl - and it is becoming their main brand. So temporarily olddomain.pl is still their "home" domain, but there is a domain alias newdomain->olddomain. The sieve file is simple: forward message and reply with vacation: ---- require ["copy","vacation"]; # rule:[redirect] if anyof (true) { redirect :copy "my.boss(a)newdomain.pl"; vacation :days 1 :addresses ["my.name(a)olddomain.pl","my.name(a)newdomain.pl"] text: I'm unavailable now. Please contact my boss: my.boss(a)newdomain.pl Greetings . ; } ---- When I send email to my.name(a)olddomain.pl - it is sent to my.boss(a)newdomain.pl and I receive the vacation message. When I send it to the alias (my.name(a)newdomain.pl) - none of above is done. Any idea how I can debug it? Running test-sieve does not help - it claims that will simply forward and deliver the message... Greetings, -- Jacek Osiecki joshua(a)ceti.pl GG:3828944 I don't want something I need. I want something I want.

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

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

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 } }
