Hi, running dovecot 2.2.33.2 with solr 7.1.0 (with new XML scheme instead of JSON) on FreeBSD produces this error message: Oct 20 20:58:29 krion postfix/smtpd[13371]: disconnect from mail-yw0-f169.google.com[209.85.161.169] ehlo=2 +starttls=1 mail=1 rcpt=1 data=1 quit=1 commands=7 Oct 20 20:58:29 krion dovecot: indexer-worker(krion(a)krion.cc): Error: fts_solr: Indexing failed: 500 Server Error Oct 20 20:58:29 krion dovecot: indexer-worker(krion(a)krion.cc): Error: fts_solr: Indexing failed: 500 Server Error Oct 20 20:58:29 krion dovecot: indexer-worker(krion(a)krion.cc): Error: Mailbox INBOX: Transaction commit failed: FTS +transaction commit failed: backend deinit (attempted to index 1 messages (UIDs 166..166)) Oct 20 20:58:30 krion dovecot: imap(krion(a)krion.cc): Connection closed (IDLE finished 451.007 secs ago) in=43 +out=812 K.

IMAP stops responding.
by Søren Peter Skou 20 Oct '17

20 Oct '17

Hiya all, I've experienced that IMAP/IMAPS stops responding. To restore service there is only one way, restart Dovecot completely. This leads to services being interrupted for some people, so it seems to only affect some of the users on the server. But POP3/POP3s is still running happily. Also, it happens more as we approach Rush Hour. All of this leads me to believe that we're facing a problem with clients somehow. I've searched the net for the problem, and dating back I've found references to Apple units being the culprit. So we've taken an old Apple client, and tried to see how many sessions it actually starts, the result of that test was that regardless what we tried it only opened one extra session. A bit of information, Debian OS : dovecot-core 2:2.2.27-1~auto+44 amd64 secure POP3/IMAP server - core files dovecot-imapd 2:2.2.27-1~auto+44 amd64 secure POP3/IMAP server - IMAP daemon dovecot-mysql 2:2.2.27-1~auto+44 amd64 secure POP3/IMAP server - MySQL support dovecot-pop3d 2:2.2.27-1~auto+44 amd64 secure POP3/IMAP server - POP3 daemon dovecot-sieve 2:2.2.27-1~auto+44 amd64 secure POP3/IMAP server - Sieve filters support the Config itself is fairly simple, lookup through MySQL to find username/password etc - I don't really see any obvious option. Also, limiting users/sessions per IP isn't really a good idea as we have a great deal of customers behind NAT. Med venlig hilsen/Best regards Søren P.

Dovecot >=2.2.29 + Filesystem quota = incorrect storage information
by Macka 18 Oct '17

Hi, I have problem with quota storage information in dovecot-2.2.29 (and newer versions, too - 2.2.30.2). I use FS quota backend. ............................ # 2.2.29.1 (e0b76e3): /etc/dovecot/dovecot.conf # OS: Linux 4.4.68-1 x86_64 mail_plugins = quota plugin { quota = fs:User quota:mount=/poczta:user quota2 = fs:Group quota:mount=/poczta:group } protocol imap { mail_max_userip_connections = 10 mail_plugins = "imap_quota mail_log notify antispam" } ................................. After upgrade from 2.2.27 to 2.2.29 (newest 2.2.30.2 too), dovecot returns incorrect informations about quota storage: # doveadm quota get -u myusername Quota name Type Value Limit % User quota STORAGE 10960896 100000 10960 or # ( echo "A1 GETQUOTAROOT INBOX"; echo "A2 logout" ) | /usr/lib64/dovecot/imap -u myusername * PREAUTH [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 BINARY MOVE NOTIFY SPECIAL-USE QUOTA] Logged in as myusername imap(myusername): Info: Logged out in=31 out=588 * QUOTAROOT INBOX "User quota" * QUOTA "User quota" (STORAGE 10960896 100000) A1 OK Getquotaroot completed (0.001 + 0.000 secs). * BYE Logging out A2 OK Logout completed (0.001 + 0.000 secs).

Replication between different versions of dovecot
by Dmitry Nezhevenko 18 Oct '17

18 Oct '17

Hi, Can't find any notes about this in documentation. Is replication supposed to work between different versions of dovecot? I've just found that dovecot 2.2.33.1 was uploaded to debian unstable and it crashes on every replication with older dovecot 2.2.27. (version 2.2.32.1 was probably ok) Summary: - 2.2.33.1 crashes when replicating from/to 2.2.27 - 2.2.32.1 probably ok when replicating from/to 2.2.27 I was able to capture backtrace of crashed doveadm-server: Program terminated with signal SIGSEGV, Segmentation fault. #0 i_stream_next_line (stream=stream@entry=0x0) at istream.c:428 428 istream.c: No such file or directory.
