Strange quota warning behavior
by Gordon Grubert 16 Oct '14

16 Oct '14

Hi, we are using dovecot 2.2.14. So far, we used the following quota warning configuration quota_rule = *:storage=10G quota_warning = storage=90%% quota-warning 90 %n quota_warning2 = storage=80%% quota-warning 80 %n quota_warning3 = storage=70%% quota-warning 70 %n This works fine. Now, we wanted to add the all clear feature for the quota warning by adding this line: quota_warning4 = -storage=70%% quota-warning 70 %n below The result is really strange. Test 1: 70% exceeded: warning3 executed => OK fall below 70%: quota_warning2 executed => NOT OK quota_warning4 executed => OK Test 2: 70% exceeded: warning3 executed => OK 80% exceeded: warning2 executed => OK fall below 80% (but still more than 70%): quota_warning executed => NOT OK fall below 70%: quota_warning2 executed => NOT OK quota_warning4 executed => OK At the moment, we are running the minimal configuration quota_warning = storage=70%% quota-warning 70 %n quota_warning2 = -storage=70%% quota-warning 70 %n below working like expected (warning when exceeding 70% and all clear when falling below 70%). Does anybody know if there is an error in our configuration or maybe, could this be a bug in dovecot? Best regards, Gordon -- Technischer Leiter & stellv.

index problem with only 1 folder of 1 box
by Guillaume 16 Oct '14

16 Oct '14

Hello, First of all, sorry for my poor english level. I pass to solr indexing. All is OK, except for the inbox of one of the mailboxes. For this inbox (other folders of the same mailbox have no problems), when i do text search, there is always no response. Others mailboxes have no problems. If i do a : "doveadm -Dv fts rescan -u mybox(a)domain.tld", i can do one and only one search with the correct response. It index the folder, take a few seconds and give me the good answer. If i redo the same search, it's extremly quick with no answers. It's like a cache problem but i don't know where and why... Logs are not very verbose... Here is an example of command line search : ---------------------------------------- $ nc 127.0.0.1 143 * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Bienvenue sur le serveur IMAP de Domain.tld 10 LOGIN "mybox(a)domain.tld" "MyBigSecret" 10 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 SEARCH=FUZZY QUOTA] Logged in 20 SELECT INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-2 unknown-9 unknown-0 unknown-10 unknown-1 unknown-4 $MDNSent unknown-3 unknown-8 $Forwarded NonJunk) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft unknown-2 unknown-9 unknown-0 unknown-10 unknown-1 unknown-4 $MDNSent unknown-3 unknown-8 $Forwarded NonJunk \*)] Flags permitted. * 8437 EXISTS * 0 RECENT * OK [UIDVALIDITY 1412669180] UIDs valid * OK [UIDNEXT 8439] Predicted next UID * OK [HIGHESTMODSEQ 20] Highest 20 OK [READ-WRITE] Select completed (0.000 secs). 30 SEARCH text "coucou" * OK Indexed 14% of the mailbox, ETA 0:57 * OK Indexed 29% of the mailbox, ETA 0:47 * OK Indexed 72% of the mailbox, ETA 0:11 * OK Mailbox indexing finished * SEARCH 35 108 153 175 176 182 348 357 360 431 472 479 520 574 575 576 577 578 586 949 984 1025 1032 1033 1034 1087 1099 1129 1284 1313 1314 1315 1366 1372 1465 1538 1711 1726 1758 1759 1969 1981 1983 1984 2036 2077 2104 2116 2162 2181 2193 2437 2504 2587 2663 2808 2809 2854 2861 2862 3076 3087 3088 3137 3188 3189 3190 3191 3192 3193 3196 3197 3250 3251 3252 3327 3328 3329 3330 3331 3332 3379 3464 3481 3494 3521 3528 3582 3589 3593 3596 3651 3667 3672 3695 3787 3789 3939 3940 3941 3942 3943 3944 3945 3946 4019 4020 4034 4043 4134 4146 4175 4241 4346 4379 4422 4490 4491 4537 4540 4542 4543 4544 4550 4627 4727 4742 4767 4790 4817 4828 4831 4839 4862 4888 4899 4901 4906 4911 4916 4957 4999 5003 5004 5008 5009 5010 5011 5012 5013 5039 5062 5081 5092 5119 5138 5145 5150 5152 5185 5186 5187 5216 5246 5247 5282 5283 5314 5316 5320 5322 5325 5337 5353 5360 5363 5385 5432 5447 5472 5485 5496 5498 5500 5528 5551 5564 5567 5595 5598 5642 5794 5841 5896 5933 5960 5961 5994 6001 6005 6016 6017 6051 6075 6125 6152 6163 6215 6238 6239 6240 6241 6287 6311 6342 6350 6353 6357 6369 6431 6472 6689 6928 6945 6951 7026 7030 7045 7046 7115 7210 7212 7214 7230 7256 7295 7298 7340 7489 7490 7492 7654 7655 7658 7660 7676 7767 7768 7800 7801 7913 7937 7956 8075 8085 8102 8111 8144 8266 8329 8333 8394 8395 8431 30 OK Search completed (36.029 secs). 40 SEARCH text "coucou" * SEARCH 40 OK Search completed (0.002 secs). 50 SEARCH text "blabla" * SEARCH 50 OK Search completed (0.002 secs). 60 LOGOUT * BYE Logging out 60 OK Logout completed. ---------------------------------------- To close this question, here is dovecot -n: ---------------------------------------- #

pop3-login segfaulting
by James Shewey 16 Oct '14

16 Oct '14

I upgraded dovecot from v1 to v2 as part of a CentOS upgrade (5.6->6.5) and am now running on 2.0.9. Any time I connect to the pop or imap ports however I get "master: Error: service(imap-login): child 2860 killed with signal 11 (core not dumped - add -D parameter to service imap-login { executable }" after following the core dump instructions at http://www.dovecot.org/bugreport.html. The problem is that I'm not sure how these processes are spawned in order to add the switch. Can I spawn them directly? If so, I ought to be able to do an strace to track down the issue as well.

Permissions problem on new installation

mmap_disable=yes not honored always
by Peter Benko 15 Oct '14

15 Oct '14

Hi all, I'm experimenting with having the mail store on a 9p file system that lacks mmap() functionality. So I disabled it in dovecot: mmap_disable = yes However, I keep getting the following error messages in my log: Oct 15 16:55:00 computer-name dovecot: imap user(a)domain.com[192.168.1.3] Error: mmap() failed with file /mail/mailboxes/domain.com/user/indexpvt-accounts/other-user/mailboxes/INBOX/dovecot.index.pvt.log: Invalid argument I only get those messages for the shared folder's private indexes. This setup works perfectly on an ext2/3/4 fs. Any opinions, is this a bug? Is mmap_disable not mandatory for all operations? Best regards, Peter

Request to list owner

Hi list owner, Sorry for this. Is it possible to change the reply-to in mailman to be the list, and not the person who replied? Also the [Dovecot] on the subject would be handy. Just two things to get better. Thanks,

permissions when moving mails
by Alexander 'Leo' Bergolth 15 Oct '14

15 Oct '14

Hi! I am using Unix groups to control access to shared mailboxes. This works fine as long as files are not moved between mailboxes that are owned by different groups. The move operation doesn't change group ownership of the mail. Is there a way to force dovecot to e.g. inherit the ownership from the parent folder, not only for new messages bot also for messages moved from one folder to another? The wiki says: http://wiki2.dovecot.org/SharedMailboxes/Permissions -------------------- 8< -------------------- When mails are copied between Maildirs, it's usually done by hard linking. If the source and destination directory permissions are different, Dovecot create a new file and copies data the slow way so that it can assign the wanted destination permissions. The source and destination permission lookups are done only by looking at the mailbox root directories' permissions, not individual mail files. This may become a problem if the mail files' permissions aren't as Dovecot expects. -------------------- 8< -------------------- Does dovecot only look at the permissions or does it also take user/group ownership into account? The behavior I experience is that even though the mailbox directories are owned by different groups, dovecot doesn't copy the mails. (See my example below.) Setting maildir_copy_with_hardlinks = no seems to fix the problem but maybe this behavior should be considered as a bug? I am using dovecot 2.2.14 and maildir mailboxes. Cheers, --leo P.S.: Here is an example of the current behavior: before the move from PAS to GSD: -------------------- 8< -------------------- GSD/.Eingang/cur/: total 0 drwxrws--- 2 nobody gsd 6 Oct 13 13:46 . drwxrws--- 5 nobody gsd 81 Oct 15 09:41 ..

Dbox and Exim
by C Peters 15 Oct '14

15 Oct '14

The Dovecot wiki [1] doesn't list either Exim, Postfix or anything else as supporting the dbox. I did some searching in the Exim archives and have found only one message mentioning dbox, sdbox or mdbox. [2] I think an RFC would go a long way towards getting the format supported. Has Timo, or anyone else, considered submitting an RFC to the IETF? My question was how are we going to use it if Exim doesn't support it. It looks like we can filter it and convert it with dovecot-lda. [3] I have generally avoided using Procmail for a few years because of various problems and it's a dead software project that hasn't been developed in what 15 to 20 years. I am thinking about trying it with Exim's built in Maildrop filtering support. Has anybody tried that? What else are people using to enable dbox? The more specific question on the problem I am trying to solve. I have been using mbox for years, and I can't even get Dovecot, IMAP and Thunderbird working on the LAN because it can't handle the GB's of old mail. Mutt works on the local machine, but I want something that works while I am using something other than ssh and mutt. For example I want to try Mailpile and K9. I would like to try dbox, but given it's lack of support in Exim or Postfix, I'll probably convert to maildir.
