[Dovecot] dsync mbox to maildir migration does not delete, deleted e-mails
by A M 15 Jan '14

15 Jan '14

Hello, I am planning to migrate all users from mbox to maildir. I am trying to do it with minimum downtime. (~100GB data) All users are currently using POP3. Dovecot version is 2.2.10 (latest). Command used is: dsync -u username mirror maildir:~/Maildir Process I plan is: (omitting steps related to sendmail / procmail) 1) keep dovecot running (with mail_location as mbox) 2) dsync for all users (this may take 3-4 hours or more) 3) (downtime starts) stop dovecot and sendmail (to stop new e-mails) 4) block pop3, imap ports on firewall (so users can not connect) 5) start dovecot (still with mbox) 6) dsync again to sync e-mails arrived between step 2 and 3 7) dsync again (just to make sure!) 8) (downtime ends) restart dovecot (with mail_location as maildir) Now, here is my problem. Lets say there is user joe, who has 50 NEW e-mails in mbox (INBOX). Step 2 perfectly syncs his 50 e-mails to 'new' folder of maildir. Now in the mean time, before step 3, he connected via POP3 and downloaded and deleted 50 e-mails. Now when we reach step 6 (re-sync), what I expected was dsync will detect that 50 e-mails are deleted and it will delete 50 e-mails from 'new' directory of maildir. But that is not happening. 50 e-mails are still there. I fear that these e-mails will be re-downloaded on his Outlook once I switch dovecot to maildir. This will happen for each and every user which will cause huge mess. So how to tell, dsync to delete non-existent e-mails which are no more there in mbox (INBOX)? Thanks in advance, Regards, A M

[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 } }

[Dovecot] it's possible to send email from the system after the mailbox quota is full
by ihab 13 Jan '14

13 Jan '14

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]

[Dovecot] Dovecot quota with MySQL - username issue
by michael 11 Jan '14

11 Jan '14

Hi all, I'm using Dovecot 2.2.8 with quota using a MySQL backend. The Quota plugin is listed for POP3, IMAP and LDA. When it is enabled for LDA, it populates the "username" field in the MySQL table with e mail addresses. I end up with a mixture of email addresses and usernames, which causes things to not fully work. It *should* be just usernames. the LDA SQL statement is: user_query = \ SELECT mailboxes.username, accounts.uid, accounts.uid AS gid, \ concat('/home/',mailboxes.username) AS home, \ (SELECT IF(accounts.new_mail_fmt=1, \ CONCAT('Maildir:',home,'/Maildir'), \ CONCAT('mbox:',home,'/Maildir:INBOX=/var/spool/mail/',mailboxes.username))) AS mail_location \ FROM mailboxes JOIN accounts ON accounts.username=mailboxes.username \ WHERE (mailboxes.email='%u' || \ (mailboxes.email=CONCAT('@','%d') AND (SELECT COUNT(email) FROM mailboxes \ WHERE email='%u') = 0) AND mailboxes.active IS TRUE) It clearly knows the username. Usernames on this system are just names, not full email addresses. The configuration of Quota Dict is: dovecot.conf dict/quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf ... quota = dict:user::proxy::quotadict dovecot-dict-sql.conf map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Can this be fixed?

[Dovecot] Possible to force cipher order?
by Matthias Rieber 10 Jan '14

10 Jan '14

Hi, is it possible to force the server cipher order instead of the clients preferences? When I connect with openssl using these ciphers: 'RC4-SHA:DHE-RSA-AES256-GCM-SHA384' -> RC4-SHA will be selected and with 'DHE-RSA-AES256-GCM-SHA384:RC4-SHA' -> DHE-RSA-AES256-GCM-SHA384 It seems to be recommended for webservers to override that due to bad clients choices and increasing knowledge, like RC4 vs. BEAST, AES128 better (theoretical) than AES256. Regards, Matthias

[Dovecot] Message filtering capability at IMAP proxy
by CM Reddy 10 Jan '14

10 Jan '14

Hi, I would like process the messages at Dovecot IMAP proxy. In one of the documents, it was mentioned that Dovecot proxy currently supports on the fly message filtering in latest releases. Will it it possible to extend the filtering feature to handle the following requirements. 1. Parse the email at IMAP proxy. 2. Replace the links with some other secure links. 3. Replace the attachments with some other document. It would be great, if any one can provide some pointers to move forward. - Thanks in advance CM Reddy

You could also chmod 1777 /var/mail but this will allow arbitrary uses who have filesystem access to create their own files here, and maybe DoS a new user from being created (or maybe even anticipate a new mailbox, create one with mode 0777 and wait to intercept mail?).

[Dovecot] imap auto create mailbox: we're not in group 8(mail)
by Adrian Zaugg 09 Jan '14

09 Jan '14

Dear List Somehow I don't understand the intended work flow to have new mailboxes auto created. On login of a new user with no mailbox, I get 2014-01-09 12:53:06 imap(tester): Error: user tester: Initialization failed: Namespace '': mkdir(/var/mail/tester) failed: Permission denied (euid=1016(tester) egid=1016(tester) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0771) The imap process runs as the user the login performed and thus it has only the privileges of that user. This is good and desired, when a mailbox already exists. I do not want to allow all users to write to /var/mail, only they should write to their dirs inside /var/mail. Same story for LMTP, if no mailbox exists yet: 2014-01-09 13:01:47 lmtp(20416, tester): Error: user tester: Initialization failed: Namespace '': mkdir(/var/mail/tester) failed: Permission denied (euid=1016(tester) egid=1016(tester) missing +w perm: /var/mail, we're not in group 8(mail), dir owned by 0:8 mode=0771) How can I configure the auto create mailbox feature that it works and let run LMTP and IMAP process as user %u and group mail and let create the mailboxes in /var/mail as (example user tester) with the following permissions: /var/mail: drwxrwx--x root mail 3072 Dec 18 01:43 . drwx------ tester tester 1024 Jan 09 12:53 tester ...or do I need a different approach?
