Hello, I upgraded Dovecot last night and have been receiving core-dumps any time I attempt to access a mailbox (via IMAP) ever since. Logging-in seems to work, but any attempt to access the mailbox contents (regardless of folder) causes a core-dump. Please let me know if I can provide any additional details. apt Sources Details: # grep "dovecot" /etc/apt/sources.list deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main deb-src http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main Package Upgrade Details: Start-Date: 2014-08-14 19:30:57 Commandline: apt-get upgrade Upgrade: dovecot-sieve:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150), dovecot-managesieved:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150), dovecot-dev:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150), dovecot-mysql:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150), dovecot-core:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150), dovecot-pop3d:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150), dovecot-imapd:amd64 (2.2.13-1~auto+138, 2.2.13-1~auto+150) End-Date: 2014-08-14 19:32:39 Filesystem Details # df -T | grep "xvda1" Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/xvda1 ext3 61796348 8037864 50612756 14% / ================= DOVECONF ================= # doveconf -n # 2.2.13 (c810e288aaed): /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-24-generic x86_64 Ubuntu 14.04.1 LTS auth_mechanisms = plain login disable_plaintext_auth = no listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_max_userip_connections = 20 mail_privileged_group = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave duplicate passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_backend = mailtrain antispam_debug_target = syslog antispam_mail_notspam = --ham antispam_mail_sendmail = /bin/bash antispam_mail_sendmail_args = /usr/local/bin/sa-learn-pipe.sh antispam_mail_spam = --spam antispam_spam_pattern_ignorecase = SPAM;JUNK antispam_trash_pattern_ignorecase = trash;Deleted * antispam_verbose_debug = 1 quota = dict:user::file:/var/vmail/%d/%n/.quotausage quota_rule2 = Trash:storage=+100M quota_rule3 = Junk:ignore quota_rule4 = INBOX:storage=+100M quota_warning = storage=100%% quota-reached 100 %u %d quota_warning2 = storage=95%% quota-warning 95 %u %d quota_warning3 = storage=80%% quota-warning 80 %u %d quota_warning4 = -storage=100%% quota-below below %u %d sieve = /var/vmail/%d/%n/.sieve } postmaster_address = postmaster(a)example.com protocols = imap pop3 sieve service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service config { unix_listener config { group = vmail mode = 0600 user = vmail } } service imap-login { client_limit = 1000 process_limit = 500 } service quota-below { executable = script /usr/local/bin/quota-below.sh unix_listener quota-below { group = vmail mode = 0666 user = vmail } user = vmail } service quota-reached { executable = script /usr/local/bin/quota-reached.sh unix_listener quota-reached { group = vmail mode = 0666 user = vmail } user = vmail } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = vmail mode = 0666 user = vmail } user = vmail } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota antispam } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota } ================= CORE DUMP ================= # gdb /usr/lib/dovecot/imap /var/vmail/example.com/user/core Reading symbols from /usr/lib/dovecot/imap...(no debugging symbols found)...done.

Moving from one Dovecot server to another Dovecot server
by Michael 28 Aug '14

28 Aug '14

Hi, I'm planning to move all mailboxes from a Dovecot 2.2.10 server to a Dovecot 2.2.9 server. Dovecot is serving virtual users only. I'm not sure if I can use dsync for that. According to the Wiki [1] the command to mirror my own mailbox should look like dsync -u mine(a)michi.su mirror ssh -i my_ssh_key vmail(a)my-mailserver.com dsync -u mine(a)michi.su Where vmail is the user that is used by Dovecot to access mail_location. I assume the above command will only mirror the mailbox of user mine(a)michi.su, right? Is it possible to sync all mailboxes with just one single command? Is it possible to sync also all ACL lists and sieve scripts? Is using dsync the right way for my purpose? Thanks, Michael [1] http://wiki2.dovecot.org/Tools/Dsync

LMTP and passdb deny=yes not working
by Jogi Hofmüller 27 Aug '14

27 Aug '14

Hi all, I start this on in a new thread. I setup the deny-user setting to temporarily prevent users from logging in and (that would be great) also stop mail delivery for said user. All this is because of our upcoming migration. Now it seems that lmtp is ignoring this setting. This is from the logfile: Aug 21 13:01:00 klee dovecot: lmtp(pid): Connect from IP Aug 21 13:01:00 klee dovecot: auth: passwd-file(fischer,IP): User found from deny passdb Aug 21 13:01:00 klee dovecot: lmtp(pid, fischer): 2UErAGzR9VMBPQAAGyzfLQ: sieve: msgid=unspecified: stored mail into mailbox 'INBOX' Aug 21 13:01:00 klee dovecot: lmtp(pid): Disconnect from 172.16.16.205: Successful quit So lmtp seems to find the user and correctly states the fact but then stores the email anyhow. Is this intended or did I hit a bug? Or do I have an error in my config? Cheers, -- j.hofmüller mur.sat -- a space art project http://sat.mur.at/

multiple IMAP sessions when connecting from one client
by Martin Vegter 27 Aug '14

27 Aug '14

Hello, I am using Postfix/Dovecot/IMAP. Everything is working fine, but I have noticed that every time I connect with Thunderbird to my server via IMAP, not one but 4 connections are being logged into /var/log/mail/mail.log: 2014-08-27 09:17:46 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12519, TLS, session=<uyb/N5cB+gBUDFRB> 2014-08-27 09:17:53 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12521, TLS, session=<jioqN5cB/ABUDFRB> 2014-08-27 09:17:53 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12523, TLS, session=<pqwwN5cB/QBUDFRB> 2014-08-27 09:17:54 dovecot: imap-login: Login: user=<martin>, method=PLAIN, rip=11.22.33.44, lip=55.66.77.88, mpid=12525, TLS, session=<cffremmc/gBUDFRB> This looks like 4 separate sessions are created when I log in from one client. Is this normal behavior? Can somebody please explain why this is so? My Dovecot version is 2.1.7 regards, Martin

LMTP during dsync migration
by Jogi Hofmüller 27 Aug '14

27 Aug '14

Hi all, Another question regarding migration. While migrating a mailbox with dsync is it safe to deliver mail via LMTP to the new (target) mailbox or is it wiser to deactivate LMTP delivery to this mailbox until it's fully migrated? And what methods could I use to stop delivery to a mailbox during migration? Our user data is stored on an LDAP server. Cheers, -- j.hofmüller http://thesix.mur.at/

Special-Use Mailboxes ?
by Per Jessen 27 Aug '14

27 Aug '14

Lots of people must have had this issue before me - users using different devices&software (pc, smartphone, tablet, thunderbird, outlook, webmail) and languages (e.g. English on the PC, German on the iPhone), some folders end of with different names - e.g. "Sent" and "Gesendete Elemente" - meaning the same thing, namely "sent mails". How do you map these to just one folder such that it shows up correctly independently of what the user happens to be using? It sounds like something for the mailbox "Sent" { special_use = \Drafts } config directive? Is that what it might be used for? mailbox "Sent" { special_use = \Sent } mailbox "Gesendete Elemente" { special_use = \Sent } -- Per Jessen, Zürich (12.9°C) http://www.dns24.ch/ - free dynamic DNS, made in Switzerland.

Object storage
by List 26 Aug '14

26 Aug '14

Timo, We are contemplating building an S3 compatible cluster of storage servers using Pithos <https://github.com/exoscale/pithos> and Cassandra to get multi data center redundancy and availability. Would it be possible to have multiple Dovecot servers in disparate geographical locations all talking to the same object storage, assuming it's consistent between sites? From what I remember about obox the dovecot servers all keep a copy of the index locally and merge it with a file in the object storage at intervals, is this an issue with our concept? Also does your team have any performance analysis data on the obox plugin, or data on it's use in production?

Running dsync results in Panic: file mbox-lock.c: line 799 (mbox_lock)

OS X 10.6 Server - Dovecot Issue
by Ian Baker 25 Aug '14

25 Aug '14

I've just taken over support for an OS X Server (v10.6.8) box, and am a bit new at Postfix & Dovecot. We're having an problem where, intermittently, dovecot seems to be bouncing messages inbound for some of my existing users. Here is the mail.log entry for a successful delivery: Aug 21 16:58:45 mail postfix/pipe[64094]: D68783AE0F75: to=<sblondin(a)eem.ca>, relay=dovecot, delay=0.08, delays=0/0.01/0/0.07, dsn=2.0.0, status=sent (delivered via dovecot service) And here is what a bounce looks like Aug 22 07:29:28 mail postfix/local[93916]: error: od[getpwnam_ext]: No record for user sblondin Aug 22 07:29:28 mail postfix/pipe[93944]: 852C43AE7ACC: to=<sblondin(a)eem.ca>, relay=dovecot, delay=15, delays=0.14/0.05/0/15, dsn=5.1.1, status=bounced (user unknown) And a bit later another succcessful delivery.

dict SQL : HA / RR load-balancing ?
by Florent Bautista 25 Aug '14

25 Aug '14

Hi everyone, I am using Dovecot 2.2 with dict SQL. My config is using : connect = host=10.111.5.1X host=10.111.5.1Y host=10.111.5.1Z dbname=mail user=quota_updater password=xxxxxxxx But when an SQL server is down, I have these messages in logs : dict: Error: mysql(10.111.5.1Y): Connect failed to database (mail): Can't connect to MySQL server on '10.111.5.1Y' (111) - waiting for 125 seconds before retry Does Dovecot support HA / RR load-balancing in dict SQL, as in passdb/userdb ? Thank you.

does dovecot assume ~ = /home/userid ?
by Per Jessen 22 Aug '14

22 Aug '14

See $SUBJ - or is there a setting somewhere to control this? I have a userid = user(a)example.com with homedir (from /etc/shadow) = /home/example.com/user, but when dovecot wants to find e.g. ~/.dovecot.sieve , it looks in /home/user(a)example.com .... Doing "su - user(a)example.com" puts me in the correct directory. -- Per Jessen, Zürich (22.3°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland.

Dovecot authentication LDAP SSL-TLS againts SAMBA4
by Lista de Dovecot 22 Aug '14

22 Aug '14

Hi, i would like to know if anybody have implemented the authentication of dovecot against samba4 via secure ldap (SSL/TLS). I made it but in plain text through dovecot´s offical page: http://wiki2.dovecot.org/AuthDatabase/LDAP/AuthBinds http://wiki2.dovecot.org/AuthDatabase/LDAP But when i try to do it in a secure way i can´t make it work. Samba4 is listening by port 636 and dovecot is speaking by 389 or 636, but they can´t comunicate themself. I´m wondering if any of you have done this before or have any clue that might help me. Thanks.

Avoid "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)"
by Florent Bautista 22 Aug '14

22 Aug '14

Hi all, I have a Dovecot setup (2.1, I will switch to 2.2 soon) with one Director and 2 backend servers. When my MX server (Postfix) tries to deliver mail to Dovecot via LMTP, it often gets an error "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)" from the Director. Service LMTP is configured with "client_limit = 1" on Director en backends (others limits are default ones). Postfix is using "lmtp_destination_recipient_limit = 1" and "lmtp_destination_concurrency_limit = 1". I want that incoming messages are stored one after one per recipient (have a queue per recipient). I does not seem to be done actually. I think Postfix is sending too many messages at a time to Director. How do you do to handle that ? I already applied the 3 patches available on the list for 2.1, but it does not seem to solve my problem... Thank you a lot. Florent

Folders don't show up
by Christian Hudon 22 Aug '14

22 Aug '14

Hello, I've upgraded to the new LTS version of Ubuntu. With that comes a new dovecot version. I think I've migrated my dovecot configuration correctly to the new version. Everything works, except that the mailboxes don't show up in the list of mailboxes in my mail clients. Trying to issue a LIST command, I see the following: CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN] Dovecot (Ubuntu) ready. 1 login USERNAME_HERE PASSWORD_HERE 1 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE BINARY MOVE] Logged in 2 LIST "" "*" * LIST (\HasNoChildren) " * LIST (\HasNoChildren) " [SNIP... A bunch of other identical lines... roughly as many as I have mailboxes] * LIST (\HasNoChildren) " * LIST (\HasNoChildren) " * LIST (\HasChildren) " 2 OK List completed. I'm not an IMAP protocol expert, but those answers to the list command don't quite look like valid IMAP to me. My imapdir has a bunch of maildir directories in it, like a normal imapdir should. Everything worked fine with the previous version of dovecot (1.2?). Maybe a dovecot bug? At least I don't see how my config could cause this. Any help would be appreciated. The output of "dovecot -n" is included below.
