[Dovecot] Subject: IMAP crash on index
by Ruan Kendall 06 Jun '11

06 Jun '11

I'm running Dovecot 1.2.15 as an IMAP server on an up-to-date Debian v6 VM. I've recently upgraded the server from a pretty crusty old Debian v4 installation, though I don't recall exactly which version of Dovecot that would have been running. I guess I could try crawling through the old logs to check if it is likely to be useful. The upgrade seemed to have gone fine and I've been using the new server for about a week, but this morning I'm finding that whilst I can successfully connect to the IMAP server using Mutt, it can't display a mail index and a quick peek at the logs shows the IMAP process falling over: (account and server IP replaced) Jun 6 10:39:27 xen dovecot: Dovecot v1.2.15 starting up (core dumps disabled) Jun 6 10:39:27 xen dovecot: auth-worker(default): mysql: Connected to localhost (mail) Jun 6 10:39:34 xen dovecot: imap-login: Login: user=<example(a)example.org>, method=PLAIN, rip=::1, lip=::1, TLS Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Panic: file mail-index-view.c: line 264 (view_lookup_seq_range): assertion failed: (first_uid > 0) Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): Raw backtrace: imap() [0x80f0e1e] -> imap() [0x80f0e82] -> imap() [0x80f0809] -> imap() [0x80ceb17] -> imap(mail_index_lookup_seq+0x26) [0x80ce5f6] -> imap() [0x80c481d] -> imap(mail_index_modseq_hdr_update+0x2e) [0x80c48ee] -> imap(mail_index_sync_ext_hdr_update+0xbb) [0x80de91b] -> imap(mail_index_sync_record+0x40f) [0x80cd57f] -> imap(mail_index_sync_map+0x2dd) [0x80cdfed] -> imap(mail_index_map+0x5c7) [0x80c3557] -> imap() [0x80bfd87] -> imap(mail_index_open+0x23f) [0x80c01ff] -> imap(index_storage_mailbox_open+0x71) [0x80abc81] -> imap(maildir_storage_sync_init+0x188) [0x8086c18] -> imap(mailbox_sync+0x31) [0x80b59d1] -> imap(imap_status_get+0x8a) [0x806f0ea] -> imap(cmd_status+0x123) [0x8065dd3] -> imap() [0x8067b5c] -> imap() [0x8067c32] -> imap(client_handle_input+0x175) [0x8067eb5] -> imap(client_input+0x5f) [0x80686ef] -> imap(io_loop_handler_run+0xd6) [0x80f9aa6] -> imap(io_loop_run+0x20) [0x80f8f20] -> imap(main+0x5b4) [0x8070f24] -> /lib/i Jun 6 10:39:35 xen dovecot: IMAP(example(a)example.org): 76] -> imap() [0x80603a1] Jun 6 10:39:35 xen dovecot: dovecot: child 20617 (imap) killed with signal 6 (core dumps disabled) I've not been able to find any mentions of this error occurring for other people. I've not looked at the source to see what the server is trying to do at this point. Restarting the IMAP service doesn't help. Any suggestions or advice?

by Jin FengMing 06 Jun '11

Hi all, I'm not so sure it is about to dovecot, but any thoughts will be appreciated. I have an email account configured as IMAP(dovecot-1.2.10) via outlook 2010. If I'm creating a *new* mailbox folder, for example "ttt", and *copying* a mail into *that* mailbox folder, then an error message window will be displayed. The problem caused by C:UID FETCH 0 (UID FLAGS RFC822.SIZE BODY.PEEK[HEADER] INTERNALDATE) S:3mgc BAD Error in IMAP command UID FETCH: Invalid uidset The dovecot's rawlog 20100101-060322-5491.in: 54nc IDLE DONE uh4m SELECT "INBOX.ttt" 37ax IDLE DONE 5dtr FETCH 1 (UID) 3mgc UID FETCH 0 (UID FLAGS RFC822.SIZE BODY.PEEK[HEADER] INTERNALDATE) 28kc IDLE DONE msxw CLOSE tuis IDLE DONE a6rl SELECT "INBOX.ttt" 59oj FETCH 1 (UID) k26b UID FETCH 1 (UID FLAGS) z8su IDLE DONE 20100101-060322-5491.out: * OK [RAWLOG TIMESTAMP] 2010-01-01 06:03:22 7u95 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS] Logged in + idling 54nc OK Idle completed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 0 EXISTS * 0 RECENT * OK [UIDVALIDITY 1262323866] UIDs valid * OK [UIDNEXT 1] Predicted next UID * OK [NOMODSEQ] No permanent modsequences uh4m OK [READ-WRITE] Select completed. + idling * 1 EXISTS 37ax OK Idle completed. * 1 FETCH (UID 1) 5dtr OK Fetch completed. 3mgc BAD Error in IMAP command UID FETCH: Invalid uidset + idling 28kc OK Idle completed. msxw OK Close completed. + idling tuis OK Idle completed. * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted. * 1 EXISTS * 0 RECENT * OK [UIDVALIDITY 1262323866] UIDs valid * OK [UIDNEXT 2] Predicted next UID * OK [NOMODSEQ] No permanent modsequences a6rl OK [READ-WRITE] Select completed. * 1 FETCH (UID 1) 59oj OK Fetch completed. * 1 FETCH (UID 1 FLAGS (\Seen)) k26b OK Fetch completed. + idling z8su OK Idle completed.

[Dovecot] file rights for dictionary file
by Michael Köhler 06 Jun '11

06 Jun '11

Hi, I use Debian Squeeze and the sources from Stephan Bosch. A few weeks ago I´ve upgraded from 2.0.11 to 2.0.13 and got an error May 29 20:01:53 mailserver dovecot: dict: Error: Can't open configuration file /etc/dovecot/dovecot-dict-sql.conf.ext: Permission denied May 29 20:01:53 mailserver dovecot: dict: Error: Failed to initialize dictionary 'quota' and I could see that /etc/dovecot/dovecot-dict-sql.conf.ext is owning by root:root with 600. After changing to root:root 644 all works, but after each upgrade all files in /etc/dovecot will be set to 600. Is it a problem of the dovecot package or should I do some changes to config to allow dovecot reading the dict file? Here is my config: # 2.0.13 (9ae30e5d6935): /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.1 ext3 auth_mechanisms = plain login cram-md5 dict { quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } first_valid_uid = 106 lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes mail_location = maildir:/var/mail/%d/%u mail_plugins = quota 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 passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { autocreate = Sent Messages autocreate2 = Deleted Messages autocreate3 = Drafts autosubscribe = Sent Messages autosubscribe2 = Deleted Messages autosubscribe3 = Drafts quota = dict:User quota::proxy::quota quota_rule2 = Deleted Messages:storage=+1GB sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service dict { unix_listener dict { group = mail mode = 0660 } } service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </etc/ssl/certs/mailserver-cert.pem ssl_key = </etc/ssl/private/mailserver-key.pem userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = quota } protocol imap { mail_plugins = quota imap_quota autocreate } local_name mailserver.makomi.de { ssl_cert = </etc/ssl/certs/mailserver1-cert.pem ssl_key = </etc/ssl/private/mailserver1-key.pem } local_name mailserver.kokoma.de { ssl_cert = </etc/ssl/certs/mailserver2-cert.pem ssl_key = </etc/ssl/private/mailserver2-key.pem } local_name mailserver.grooveb.de { ssl_cert = </etc/ssl/certs/mailserver3-cert.pem ssl_key = </etc/ssl/private/mailserver3-key.pem } local_name mailserver.koehler-gohlis.de { ssl_cert = </etc/ssl/certs/mailserver4-cert.pem ssl_key = </etc/ssl/private/mailserver4-key.pem } local_name mailserver.koehler-schroeder.de { ssl_cert = </etc/ssl/certs/mailserver5-cert.pem ssl_key = </etc/ssl/private/mailserver5-key.pem } Greetings, Michael

[Dovecot] Bug: Fixed a duplicate
by Tom Sommer 06 Jun '11

06 Jun '11

I restored a dovecot mailserver today, and when I started the server again, the logs filled up with "Fixed a duplicate" warnings. This in itself it not a problem, the problem is that it appears the fix is not done correct. Consider this: Warning: Fixed a duplicate: [X]/cur/1305907573.V807I37682f3M146183.mail8.xxx.com:2,S -> 1306601066.M382668P27710.mail8.xxx.com The problem appears to be the timestamp of this new file isn't updated correctly. Now I got hundreds of mailboxes filled with mails named 1305907573.* with random (in the past) timestamps, leading to mangled miss-sorted inboxes for customers. 3575 May 25 02:05 1306600913.M982997P26976.mail8.xxx.com:2,S 55313 May 6 01:50 1306600913.M982998P26976.mail8.xxx.com:2,S 9839 May 7 23:59 1306600913.M982999P26976.mail8.xxx.com:2,S 3453 May 10 01:32 1306600913.M983000P26976.mail8.xxx.com:2,S 16616 May 14 00:22 1306600913.M983001P26976.mail8.xxx.com:2,S 68850 May 25 00:46 1306600913.M983002P26976.mail8.xxx.com:2,S etc. Dovecot is v. 2.0.11 I guess I should have deleted all dovecot.* files after the restore, before I started dovecot? // Tom

[Dovecot] Custom sql query for keeping quota with dict-sql
by Marcin Mirosław 05 Jun '11

05 Jun '11

Hello! I'd like to setup quota for for virtualusers, i'm using both maildir++ and mdbox as storage, and i'm using postgresql to keep users. I'm keeping all users data in one table: [...] login text NOT NULL, domain text, password text, quota_mb integer NOT NULL DEFAULT 0 [... other columns ...] i'd like to keep present quota in such two columns: quota_dict_bytes integer NOT NULL DEFAULT 0, quota_dict_messages integer NOT NULL DEFAULT 0 I read wiki a little and it looks i can't define own sql queries, they appear to be hardcoded. Am i wrong? Is it possible to write own queries to get/set quota using such table schema? Or maybe there is diffrent way to track quota for diffrent storages? Regards! Marcin
