You should really post your complete dovecot config (dovecot -n output + any ".ext" files) so that we can get a better picture.

Unable to get virtual users set up with database auth
by Cliff Hayes 16 Oct '14

16 Oct '14

I can't seem to get imap virtual users to work with database authentication on new Scientific Linux 6.5 server with Sendmail 8.14.4 & Dovecot 2.0.9 Apparently I have to also create system users because sendmail/procmail/dovecot want to check directory ownership. So I created a database, made entry for the user, created the user chayes on the system. But %u always contains just chayes instead of chayes(a)domain.tld even though I tried different select statements to put the entire username in the username field. This causes the following errors: Oct 16 00:10:26 avalon sendmail[2536]: s9G5APo9002535: forward /var/spool/mail/chayes(a)domain.tld/chayes/.forward.avalon: Group writable directory Oct 16 00:10:26 avalon sendmail[2536]: s9G5APo9002535: forward /var/spool/mail/chayes(a)domain.tld/chayes/.forward: Group writable directory Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: Effective uid=497, gid=497, home=/var/spool/mail/chayes(a)domain.tld/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: Home dir not found: /var/spool/mail/chayes(a)domain.tld/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: Namespace : type=private, prefix=, sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes location=mbox:/var/spool/mail/chayes:INBOX=/var/spool/mail/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Debug: fs: root=/var/spool/mail/chayes, index=, control=, inbox=/var/spool/mail/chayes Oct 16 00:10:26 avalon dovecot: lda(chayes): Error: user chayes: Initialization failed: Namespace '': mbox: mbox root directory can't be a file: /var/spool/mail/chayes (http://wiki.dovecot.org/MailLocation/Mbox) Oct 16 00:10:26 avalon dovecot: lda(chayes): Fatal: Invalid user settings.

[Dovecot/VirtualUsers/VirtualMailBoxes] No mails into mua
by aleskandro 16 Oct '14

16 Oct '14

Hi all, I've configured postfix with multiple host and virtual mailboxes (main.cf is here: http://pastebin.com/798VVxbv) So I can receive email to vuser(a)mydomain.tld into /var/mail/vhosts/mydomain.tld/vuser file. Now I'm configuring dovecot 2.2.13-r1; this is my dovecot -n and /etc/dovecot/passwddir/mydomain.tld/passwd: http://pastebin.com/b4xcjj7t - The auth and server subscribe from a mua is ok and in the vuser file there are some mails but I can't see them in my mua. mail.log doesn't report any error. Where I'm wrong? Aleskandro

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 15 Oct '14

15 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.

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

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.

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.

Proxy problem: "[COMPRESSIONACTIVE] TLS compression already enabled"

bandwidth shaping
by Alan Bailward 14 Oct '14

14 Oct '14

Hey all, sorry if this has been asked before, but I haven’t really found a good solution. I have a mac at home and randomly, maybe once a week or once a month, Mail.app will go crazy and use as much bandwidth as I have to pull down mail. I’m not home so I can’t tell what it’s done or why, and sometimes it stops after an hour, sometimes it goes all night, leaving me with a potentially big bandwidth bill for my colo’d server which hosts my mail (dovecot 1.2.9, postfix 2.7.0 on Ubuntu LTS 10.04). I’m wondering if there’s a way to restrict bandwidth that’s the “accepted” and proper way with dovecot? There isn’t anything (AFAICT) built into dovecot, and the alternative seems to be setting up bandwidth shaping with ‘ip’, but that is a pretty horrible nest of ugliness. Is there a fairly simple setup to set it so imap/pop traffic can only ever use 1mb/s (or some arbitrary number)? I’m not looking for a one liner, but each time this happens I say “I’m going to figure this out and fix this”, then get lost in ip and shaping queues and give up in frustration until the next time it happens, when I say “I’m *really* going to figure this out this time…”. Anyone have any pointers? TIA Alan

auth-worker goes wild
by Hans Morten Kind 14 Oct '14

14 Oct '14

dovecot-2.2.13 running on Solaris-10, app 5000 concurrent connections, and a pretty standard config where passdb is set up with driver = pam. We have had some situations where an auth-worker gets into a loop, the load on the server rises and the auth-master seems blocked untill finally no new imap nor pop session are accepted. A 'doveadm reload' restores normal operations. With debug logging enabled we are observing this: auth: Debug: pam(,10.10.30.33,<7WMu3UkEGQCBsR4h>): cache miss auth-worker(24556): Debug: pam(,10.10.30.33): lookup service=dovecot auth-worker(24556): Debug: pam(,10.10.30.33): #1/1 style=2 msg=Please enter user name: ... auth-worker(24556): Debug: pam(,10.10.30.33): #1/1 style=2 msg=Please enter user name: etc etc After some time dovecot only logs Warning: Auth process not responding, delayed sending initial response (greeting) Disconnected: Auth process broken (disconnected before auth was ready, waited 26 secs) 'truss -wall -aep PID' on the looping auth-worker shows the loop: 0.0757 write(2, 0x080AE0C0, 71) = 71 0101 2 4 5 5 6 p a m ( , 1 0 . 1 0 . 3 0 . 3 3 ) : # 1 / 1 s t y l e = 2 m s g = P l e a s e e n t e r u s e r n a m e : \n 0.0826 write(2, 0x080AE0C0, 71) = 71 0101 2 4 5 5 6 p a m ( , 1 0 . 1 0 . 3 0 . 3 3 ) : # 1 / 1 s t y l e = 2 m s g = P l e a s e e n t e r u s e r n a m e : \n The host at 10.10.30.33 is running RoundCube for app 1000 concurrent users. This problem started after we provided our users RoundCube, and every time we end up in this stuck situation, it is the RoundCube-server making the connections where the username has zero length. I am unable to reproduce how RoundCube puts dovecot into this mess. With the enclosed patch installed, the loop terminates and normal operation are restored immediately: auth: Debug: pam(,10.10.30.33,<Q8kV6AEFYwCBsR4h>): cache miss auth-worker(18658): Debug: pam(,10.10.30.33): lookup service=dovecot auth-worker(18658): Debug: pam(,10.10.30.33): #1/1 style=2 msg=Please enter user name: auth-worker(18658): Fatal: NO USER? auth-worker(18658): Error: Raw backtrace: 0xfef0798c -> 0xfef06d3b -> 0x807ca6e -> 0xfecc460e -> 0xfecc1d1e -> 0xfe3c0af4 -> 0xfecc2608 -> 0xfecc27f1 -> 0x807cc5e -> 0x807d162 -> 0x807d310 -> 0x8069ca1 -> 0x806ab72 -> 0x806aeec -> 0xfef1e866 -> 0xfef2001c -> 0xfef1e9ff -> 0xfef1e956 -> 0xfeeb0172 -> 0x8071bf2 -> 0x805a650 auth: Error: auth worker: Aborted PASSV request for : Worker process died unexpectedly I think however, that the pam driver should not have been initiated when the username has zero length, definitely there is nobody around to answer the prompt for a username ... hmk

Doveadm quota recalc sets quota for wrong quota root
by Rick van den Hof 14 Oct '14

14 Oct '14

Hi, In our setup, we use two quota roots. One for user quota and one for domain quota. If a user has no quota, then the domain quota is applied. For a user with user quota this is how it looks: # doveadm quota get -u test(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1439155 2560000 56 Domain quota MESSAGE 21257 - 0 User quota STORAGE 0 102400 0 User quota MESSAGE 0 - 0 In this case, the whole domain contains 21257 messages but the account itself contains 0. For a user with only domain quota, this is how it looks: # doveadm quota get -u rick(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1439155 2560000 56 Domain quota MESSAGE 21257 - 0 User quota STORAGE 693299 - 0 User quota MESSAGE 12876 - 0 So far so good. My account contains 12876 messages. Now I've sent a message containing a 1mb.bin as attachment to test(a)shellz.nl: # doveadm quota get -u test(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1440540 2560000 56 Domain quota MESSAGE 21258 - 0 User quota STORAGE 1384 102400 1 User quota MESSAGE 1 - 0 Seems to be fine, the message on disk is indeed 1.4MB and this has been added to both domain and user quota. Now see what happens when I run the following command: # doveadm quota recalc -u test(a)shellz.nl # doveadm quota get -u test(a)shellz.nl Quota name Type Value Limit % Domain quota STORAGE 1384 2560000 0 Domain quota MESSAGE 1 - 0 User quota STORAGE 1384 102400 1 User quota MESSAGE 1 - 0 The recalc action has updated the domain usage to reflect the specific user's usage (my 12876 messages are no longer counted). We log domain usage (usage_domain) in a seperate table from mailbox usage (usage_mailbox). These are the queries that set the usage: 256 Query BEGIN 256 Query DELETE FROM usage_domain WHERE domain = 'shellz.nl' 256 Query DELETE FROM usage_domain WHERE domain = 'shellz.nl' 256 Query INSERT INTO usage_domain (bytes,domain) VALUES ('1418118','shellz.nl') ON DUPLICATE KEY UPDATE bytes='1418118' 256 Query INSERT INTO usage_domain (messages,domain) VALUES ('1','shellz.nl') ON DUPLICATE KEY UPDATE messages='1' 256 Query COMMIT 257 Query BEGIN 257 Query DELETE FROM usage_mailbox WHERE userdomain = 'test(a)shellz.nl' 257 Query DELETE FROM usage_mailbox WHERE userdomain = 'test(a)shellz.nl' 257 Query INSERT INTO usage_mailbox (bytes,userdomain) VALUES ('1418118','test(a)shellz.nl') ON DUPLICATE KEY UPDATE bytes='1418118' 257 Query INSERT INTO usage_mailbox (messages,userdomain) VALUES ('1','test(a)shellz.nl') ON DUPLICATE KEY UPDATE messages='1' 257 Query COMMIT How do I prevent this from happening? It should only update the usage_mailbox table when I run the recalc command. Could this be because we use seperate tables for domain and user usage? dovecot -n: # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.13.0-37-generic x86_64 Ubuntu 14.04.1 LTS auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890+=_.-@& dict { expire = mysql:/etc/dovecot/dovecot-sql-expire.conf quotadomaindict = mysql:/etc/dovecot/dovecot-sql-quota-domain.conf quotauserdict = mysql:/etc/dovecot/dovecot-sql-quota-user.conf } disable_plaintext_auth = no listen = *,[::] mail_fsync = never mail_location = maildir:~/Maildir mail_plugins = quota expire 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 passdb { args = /etc/dovecot/dovecot-sql-user.conf driver = sql } plugin { expire = Trash expire2 = Spam expire_dict = proxy::expire mail_log_events = delete copy save expunge mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:Domain quota:%d:proxy::quotadomaindict quota_rule2 = Trash:ignore quota_warning = storage=99%% doquotawarning 99 %u quota_warning2 = storage=95%% doquotawarning 95 %u quota_warning3 = storage=75%% doquotawarning 75 %u quota2 = dict:User quota::proxy::quotauserdict quota2_rule2 = Trash:ignore quota2_warning = storage=99%% doquotawarning 99 %u quota2_warning2 = storage=95%% doquotawarning 95 %u quota2_warning3 = storage=75%% doquotawarning 75 %u } protocols = imap pop3 service auth-worker { unix_listener auth-worker { mode = 0600 user = vmail } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { mode = 0600 user = vmail } unix_listener auth-userdb { mode = 0600 user = vmail } user = vmail } service dict { unix_listener dict { mode = 0600 user = vmail } } service doquotawarning { executable = script /usr/bin/doquotawarning.py unix_listener doquotawarning { user = vmail } user = vmail } service imap-login { chroot = process_limit = 200 process_min_avail = 2 } service imap { executable = imap postlogin } service managesieve-login { chroot = } service pop3-login { chroot = process_limit = 50 process_min_avail = 2 } service pop3 { executable = pop3 postlogin } service postlogin { executable = script-login /usr/local/postfixint/dolastlogin.py user = $default_internal_user } ssl_cert = </etc/ssl/certs/wild.totaal.net/wild.totaal.net.pem ssl_cipher_list = ALL:!LOW:!SSLv2:ALL:!aNULL:!ADH:!eNULL:!EXP:RC4+RSA:+HIGH:+MEDIUM ssl_key = </etc/ssl/certs/wild.totaal.net/wild.totaal.net.key userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql-user.conf driver = sql } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_logout_format = bytes=%i/%o mail_max_userip_connections = 50 mail_plugins = quota imap_quota mail_log notify expire } protocol pop3 { mail_max_userip_connections = 50 mail_plugins = quota expire pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s, bytes=%i/%o pop3_uidl_format = %f } protocol lda { deliver_log_format = msgid=%m: %$ mail_fsync = optimized mail_plugins = quota sieve expire postmaster_address = hostmaster(a)vps04.totaal.net rejection_reason = Your message to <%t>' was automatically rejected:%n%r } dovecot-sql-quota-domain.conf: connect = xxx map { pattern = priv/quota/storage table = usage_domain username_field = domain value_field = bytes } map { pattern = priv/quota/messages table = usage_domain username_field = domain value_field = messages } dovecot-sql-quota-user.conf: connect = xxx map { pattern = priv/quota/storage table = usage_mailbox username_field = userdomain value_field = bytes } map { pattern = priv/quota/messages table = usage_mailbox username_field = userdomain value_field = messages } Thanks in advance to anyone who might be able to shed some light in this situation :).

Sorry for the replay to sender instead of the list. As I originally wrote, my need is script or a command like the old Expire_mail.pl that parse a local mbox folder and move/copy mail older than NN days to another local mbox folder. Probably for a Perl programmer is only matter of modify this script or something similar. I searched in docs, wiki, ... but not noticied something that can simply be inserted in a cron job to do the work. Only migration tools or complex (for me), library that can be used to manipulate folders :-) Thanks, F.

[Pigeonhole Sieve interpreter] :create argument and lda_mailbox_autosubscribe setting
by Vivien Lacourba 14 Oct '14

14 Oct '14

Hi, I am using dovecot and dovecot-sieve packages from Debian Wheezy (2.1.7-7+deb7u1). I noticed that while using ":create" (from the mailbox extension) in my Sieve filter and "lda_mailbox_autosubscribe = yes" in Dovecot's LDA config it automatically subscribes to the destination mailbox even if that mailbox already existed. Reading Dovecot's documentation and the mailbox extension RFC it seems subscription should happen only if it is a newly created mailbox and should not happen if the mailbox already existed. http://tools.ietf.org/html/rfc5490#section-3.2 [[ 3.2. ":create" Argument to "fileinto" Command (...) If the mailbox already exists, this argument is ignored. (...) ]] /etc/dovecot/conf.d/15-lda.conf [[ # Should automatically created mailboxes be also automatically subscribed? lda_mailbox_autosubscribe = yes ]] Also I noticed that if I don't use ":create" in my filters and instead set "lda_mailbox_autocreate = yes" in Dovecot's LDA config, then this time the behavior looks correct as the automatic subscription will only happen for a newly created mailbox.

Larry & Pascal, Thanks for the reply.

To dovecot-ee or not to dovecot-ee
by Jens Dueholm Christensen 13 Oct '14

13 Oct '14

Hi At the moment I'm running an ageing 2.0.13 install that need to be upgraded and moved to new HW. I was looking around, and saw that dovecot-ee is listed as a "free" (ie. 0$) product on dovecot.fi. Apart from the need to register an account in order to "purchase" an -ee license, are there any cavats by switching to the -ee version compared to compiling and running the regular releases? I've got no problems with downloading, building and installing the normal releases and I have no need for object storage, so will the -ee version give me anything else but access to a YUM repo and RPM packages? Regards, Jens Dueholm Christensen Survey IT

Dovecot domain quota
by Filip Bartmann 13 Oct '14

13 Oct '14

I have dovecot version 2.1.7 and I have quota configured as: ----------------------------------- dict { quota_domain = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } mail_plugins = quota protocol imap { mail_plugins = quota quota imap_quota } plugin { quota = dict:domain:%d:proxy::quota_domain quota_rule = *:storage=1M quota_rule2 = Trash:storage=+100M } ----------------------------------- /etc/dovecot/dovecot-dict-sql.conf.ext: ----------------------------------- map { pattern = priv/quota/storage table = quota_dict username_field = domain value_field = bytes } map { pattern = priv/quota/messages table = quota_dict username_field = domain value_field = messages } map { pattern = shared/expire/$user/$mailbox table = expires value_field = expire_stamp fields { username = $user mailbox = $mailbox } } ----------------------------------- But the problem is that quota table created as: ----------------------------------- CREATE TABLE `quota_dict` ( `domain` varchar(255) NOT NULL, `bytes` bigint(20) NOT NULL DEFAULT '0', `messages` int(5) NOT NULL DEFAULT '0', PRIMARY KEY (`domain`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ----------------------------------- counts quota only for last user as defined /etc/dovecot/users or in database table. So if I have in /etc/dovecot/users (the contents is from testing VPS): ----------------------------------- test@debian.jd:{plain}radegast:8:8::/srv/mail/debian.jd/::userdb_quota_rule=*:storage=500k bartmann@debian.jd:{plain}radegast:8:8::/srv/mail/debian.jd/::userdb_quota_rule=*:storage=500k ----------------------------------- After running `doveadm quota recalc -A` I have in my db: ----------------------------------- +-----------+--------+----------+ | domain | bytes | messages | +-----------+--------+----------+ | debian.jd | 505758 | 81 | +-----------+--------+----------+ ----------------------------------- whith is from account bartmann(a)debian.jd not both accounts at testing VPS domain debian.jd. The same is with quota enforcing - quota if enforced on the latter of the accounts in /etc/dovecot/users on testing machine or database in production machine. What I do wrong? Thanks Filip Bartmann

delete/archive old mail
by sottilette＠rfx.it 13 Oct '14

13 Oct '14

Hi everybody, I store user's mail in the old mbox format. I have many scripts to manage users that works fine with mbox. I use the very old Expire_mail.pl script to delete mail older than NN days for selected users (nightly cron job). Still works fine with my CentOS dovecot-2.0.16. Now I want move the mail to a sort of archive folder instead of simply deleting it from the inbox for some users. Is there a similar script or some simple triks? Thanks, F.

2.2.14rc1 - dsync in backup mode still changes source permissions
by Peter Mogensen 13 Oct '14

13 Oct '14

Hi, It seems we are still able to reproduce this: http://www.dovecot.org/list/dovecot/2014-May/096367.html However... there's no longer any error-messages. It just silently changes permissions on some dovecot files in the source maildir. (most often dovecot-uidlist) We're running dsync as root, with hardwired userdb values for other reasons. So it has the OS permissions to change source. But still, running in "backup" shouldn't change source ever, should it? The command line is of this format - running on destination-host: # dsync -R -o mail_home=/users/user/maildir backup ssh -c arcfour -o StrictHostKeyChecking=no -i /root/.ssh/id-rsa-dsync source-host "dsync -o mail_home=/users/user/maildir" /Peter

Permissions for shared mail don't work
by Damien Desfontaines 12 Oct '14

12 Oct '14

Good morning, I'm using dovecot v.2.1.7 on Debian Sid, and the output of dovecot -n is available here: http://paste.fulltxt.net/C-O I'm trying to make the mailbox of (system) user "spam" available to user "ted". I followed these instructions: http://wiki2.dovecot.org/SharedMailboxes/Permissions and it doesn't seem to work. To be more precise: - I manually (and recursively) changed the permissions of all files in ~spam/Mail to 660 (and 770 for the directories); - I manually (and recursively) changed the group owner of everything in ~spam/Mail to "mailperso", where "mailperso" is a group whose users are spam and ted; - I added « mail_access_groups=mailperso » into my dovecot config; - and I restarted dovecot. But still, when I send a new email to spam, it appears as being owned by group "spam" and having permissions set to 600, so I can't access it with user "ted". I also tried to set the setgid bit for ~spam/Mail, it didn't change anything, and when I recursively set the setgid for all subdirectories of ~spam/Mail, it gives new mails the correct group (mailperso) but not the correct permissions. Have I missed something, or is this a bug? Thanks in advance and best regards, Damien

Hi, I'm new to dovecot, and I was reading the manual, to use SQL auth along with virtual domains. So far, it's perfect and does what I need, except for one thing. For each new user, does the directories on the filesystem will be auto-created on 1st login? Thanks in advanced,

dovecot replication (active-active) - server specs
by Martin Schmidt 11 Oct '14

11 Oct '14

Hello, i have some questions about the new dovecot replication and mdbox format. my company has currently 3 old dovecot 2.0.x fileserver/backend with ca. 120k mailboxes and ca. 6 TB data used. They are synchronised per drbd/corosync. Each fileserver/backend have ca. 40k mailboxes im Maildir format. Our MX server is delivering ca. 30 GB new mails per day. Two IMAP proxy server get the connections from the users. Atm. without dovecot director. We've got around 700k connections per day (imap 200k / pop3 500k) The system is getting issues because the fileserver still have old slow HDDs. Users sometime get connection timeouts, because the fileserver can not answer fast enough due to I/O waiting lag. So we want to make a new system. We desire the new system to use mdbox format ( bigger files, less I/O) and replication through dovecot replication (active/active) instead of drbd. Each fileserver should know every mailbox/user and for the time being 2 dovecot proxies for the user connections (IMAP/POP). (later after the migration from the old system to the new, dovecot director instead of proxies, for caching reasons). we've got 2 new fileservers, they have each SSD HDDs for "new-storage" and 7200rpm SATA HDDs on RAID 5 with 10 TB for "alt-storage" 32 GB RAM per Server Do you have some tips for the system? Do you believe 32 GB RAM are enough for one fileserver each and have you experience with the I/O Waiting problem with huge amounts of Data on the alt-storage? Could there be issues with the RAM, if one fileserver has a downtime, so the second one has to take over all mailboxes for a short amount of time? In general are only 2 new fileserver enough or should we think in bigger dimensions, like 4 fileserver Storage expansion in the new servers should not be a problem (bigger HDDs and a few slots free, so we can expand the raid 5). thank you kind regards Martin Schmidt

Dear Mailing List, (version and dovecot -n at the bottom) (Sorry for the bad English in this mail :) ) I'm new to dovecot and wanted to build my own mailserver using dovecot+postfix. I currently have a Problem with Permissions with my mailfolder. I could solve it easily if i set it with chmod to 777. but thats no real solution. While reading my log files i see a lot messages like: Oct 10 05:19:52 lda(owncloud): Error: user owncloud: Initialization failed: Initializing mail storage from mail_location setting failed: stat(/home/vmail/example.com/owncloud/mail) failed: Permission denied (euid=100(owncloud) egid=1004(owncloud) missing +x perm: /home/vmail, dir owned by 5000:5000 mode=0700) Oct 10 05:19:52 lda(owncloud): Fatal: Invalid user settings. Refer to server log for more information. So Currently two Users need to acces the mail-folder: 1. The user itself (here: owncloud) 2. The vmail user I want to use dovecot with virtual users. Now the question is: shouldn't the directory be accessed only by the vmail user? and not by the owncloud user? Second Quest: If it's correct that the access is made by 2 users: what rights do they need? I Cant add all users to the group vmail and set g+rwx Permissions (every user could read mails from other users, and even edit them!) Thanks a Lot.

]UG] Dovecot 2.2.9 SSL client cert verification fails: openssl verify: OK
by Daniel Dickinson 11 Oct '14

11 Oct '14

Greetings all, I have verified a bug that has long been attributed to lack of knowledge on the part of the user. Dovecot rejects StartSSL client certificates due to reject StartSSL root CA when doing client verification even though the appropriately constructed ca-bundle.pem has been created and applied vi ssl_ca = </etc/dovecot/ca-bundle.pem. openssl verify -CAfile ca-bundle.pem -crl_check_all -policy_check -x509_strict -verbose client-cert.pem returns: client-cert.pem: OK However dovecot reports the following: Oct 11 01:41:17 hostname dovecot: imap-login: Invalid certificate: unable to get local issuer certificate: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority Oct 11 01:41:17 hostname dovecot: imap-login: Invalid certificate: certificate not trusted: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority Oct 11 01:41:17 hostname dovecot: imap-login: Invalid certificate: unable to get certificate CRL: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority Oct 11 01:41:17 hostname dovecot: imap-login: Valid certificate: /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Class 1 Primary Intermediate Client CA Also reports the client certificate as valid. The certificate bundle was created as follows: openssl x509 -in sub.class1.client.pem -subject -issuer >ca-bundle.pem cat class1-client-crl.pem >>ca-bundle.pem openssl x509 -in startcom-root-ca.pem -subject -issuer >>ca-bundle.pem cat startcom-root-ca-crl.pem >>ca-bundle.pem Furthermore exim, Thunderbird, and Firefox are all perfectly happy with the certificates (and exim has no problem verifying the client certificates). Further, there are many more messages regarding issues with users of dovecot having issues with StartCom client certificates who have reported following all the steps than with Cyrus or Courier. Oh, and client verification of server-side certificate works fine with server-side certificate bundle (cat server.pem startcom-intermediate.pem startcom-root-ca.pem >dovecot.pem) Relevant dovecot -n included below: auth_debug = yes auth_mechanisms = plain login digest-md5 cram-md5 otp auth_ssl_require_client_cert = yes auth_verbose = yes ssl = required ssl_ca = </etc/dovecot/ca-bundle.pem ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem ssl_verify_client_cert = yes verbose_ssl = yes OS is Debian Wheezy with latest updates and (just today in hopes it had been fixed, same error occurs with Wheezy's dovecot = 2.1.7) dovecot 2.2.9 from backports. amd64 architecture.

Migrating to Dovecot EE

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone! I am currently running dovecot 2.2.9 on my Debian Wheezy system.

I already have access to the repository, and now before I starting "apt-getting" all kinds of packages: What would be the best way on moving to the Dovecot EE repository? Just doing an apt-get install dovecot-ee? Will it replace the current version? Or should the old version be removed before installing the new one?

Second Quest: If it's correct that the access is made by 2 users: what rights do they need? I Cant add all users to the group vmail and set g+rwx Permissions (every user could read mails from other users, and even edit them!) Thanks a Lot.

Keywords & sync
by Ralf Hildebrandt 10 Oct '14

10 Oct '14

We're using keywords within Thunderbird, and we're syncing those using IMAP. When using more than 5 keywords, we're envcountering problems - they're only partially being synced (between two clients, but not all clients). Any idea why this could be happening? The introduction of tagging in Thunderbird is described here: <https://bugzilla.mozilla.org/show_bug.cgi?id=114656> -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Send an alert on master user login
by Andre Rodier 09 Oct '14

09 Oct '14

Hello, I want to know if there is an option in Dovecot to send an alert, or run a script when someone is using the master user facility. I can do something myself with fail2ban, but maybe there is an option in Dovecot? Thanks. André.

Sieve filter extracting wrong header value on certain mail messages
by gowen (dovecot) 09 Oct '14

09 Oct '14

# 2.2.12: /etc/dovecot/dovecot.conf # OS: Linux 3.15.4-x86_64-linode45 x86_64 openSUSE 12.3 (x86_64) Short version: 1) I filter out spam by using a dovecot sieve filter to act based on a header inserted by bogofilter 2) In some cases, sieve fails to correctly file based on this header 3) Testing with sieve-test indicates that it's testing the wrong header 4) Suggestions? Am I doing something wrong? Is there a problem with these headers that bends test-sieve out of shape? 5) Test files from below are also available via http://www.swynwyr.com/sieve-test/ Any help is appreciated!!! Long version with full details: Here is the simple sieve filter I'm using to test, and two different variants of an email which triggers this problem. I basically deleted things one by one from an original email (1) to get minimal testcases that triggered (2) or did not trigger (3) the problem. The filter: === begin test.sieve === require ["fileinto", "body", "regex"]; if header :contains "X-Bogosity" "Spam," { fileinto "SPAM.SPAM"; stop; } elsif header :contains "X-Bogosity" "Unsure," { fileinto "SPAM.UNSURE"; stop; } keep; stop; === end test.sieve === Here is an example email that will cause this filter to not function as expected: === begin message.2 === Return-Path: <alora(a)promosforusio.org> Subject: =?utf-8?B?QUhTIEtpdGNoZW4gTWFrZW92ZXIgR2l2ZWF3YXkg?= Subject: ÎHS KitÑhen ÎakÐµovÐµr GivÐµaway Subject: =?ISO-8859-1?Q?AHS Kitchen Makeover Giveaway =A0=A0=A0?= Subject: Subject: AHS Kitchen Makeover Giveaway X-Bogosity: Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3 Home Warranty Summer Giveaway === end message.2 === If I run test-sieve on this, we can clearly see in the trace log that when it's supposed to test for header "X-Bogosity" it in fact looks at one of the multiple "Subject" headers. Note that the result is storing in INBOX rather than SPAM.SPAM, and that the "matching value" for "X-Bogosity headers" is actually the contents of the final "Subject" header in the test on line 3. In the second test, on line 6, it uses a different and correct value for the same header! But too late to help as the first test was the one it should have had a match on. === begin session === $ sieve-test -t trace2.log -Tlevel=matching test.sieve message.2 Performed actions: * store message in folder: INBOX Implicit keep: (none) sieve-test(gowen): Info: final result: success $ cat trace2.log ## Started executing script 'test' 3: header test 3: starting `:contains' match with `i;ascii-casemap' comparator: 3: extracting `X-Bogosity' headers from message 3: matching value `AHS Kitchen Makeover Giveaway' 3: with key `Spam,' => 0 3: finishing match with result: not matched 3: jump if result is false 3: jumping to line 6 6: header test 6: starting `:contains' match with `i;ascii-casemap' comparator: 6: extracting `X-Bogosity' headers from message 6: matching value `Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3' 6: with key `Unsure,' => 0 6: finishing match with result: not matched 6: jump if result is false 6: jumping to line 11 11: keep action; store message in default mailbox 12: stop command; end all script execution ## Finished executing script 'test' $ === end session === Now lets remove the "Return-Path" from that message. (Of the original 26 headers, all but the 7 shown in message.2 could be removed and still have this message break the filter). This alters thing enough that sieve starts working as expected (in fact, removing any one of the 6 non-X-Bogosity headers will cause this to start working). === begin message.3 === Subject: =?utf-8?B?QUhTIEtpdGNoZW4gTWFrZW92ZXIgR2l2ZWF3YXkg?= Subject: ÎHS KitÑhen ÎakÐµovÐµr GivÐµaway Subject: =?ISO-8859-1?Q?AHS Kitchen Makeover Giveaway =A0=A0=A0?= Subject: Subject: AHS Kitchen Makeover Giveaway X-Bogosity: Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3 Home Warranty Summer Giveaway === end message.3 === Now when we run test-sieve it works as expected, filing into SPAM.SPAM and showing the correct matching value for line 3: === begin session === $ sieve-test -t trace3.log -Tlevel=matching test.sieve message.3 Performed actions: * store message in folder: SPAM.SPAM Implicit keep: (none) sieve-test(gowen): Info: final result: success $ cat trace3.log ## Started executing script 'test' 3: header test 3: starting `:contains' match with `i;ascii-casemap' comparator: 3: extracting `X-Bogosity' headers from message 3: matching value `Spam, tests=bogofilter, spamicity=1.000000, version=1.2.3' 3: with key `Spam,' => 1 3: finishing match with result: matched 3: jump if result is false 3: not jumping 4: fileinto action 4: store message in mailbox `SPAM.SPAM' 5: stop command; end all script execution ## Finished executing script 'test' $ === end session ===

mailbox in different filesystem
by Héctor Moreno Blanco 08 Oct '14

Hello everyone, We have Dovecot 2.1.6 with Maildir. We would like to perform some kind of mail archiving with a mailbox in a different storage, for example a mailbox called ARCHIVED, with different disks (slower...). Is possible to locate this mailbox in other storage (SAS, Fiber...) and how can we do it? Thank you very much in advanced. Kind regards.

dovecot 2.1 new imap folder permissions
by Stefanos Gerangelos 07 Oct '14

07 Oct '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I hope this is the appropriate place to ask. I am migrating an old mail (postfix/dovecot) server to a new one. Everything works much as expected. I have a small obstacle though. I use mbox format and the setup is pretty much simple. Suppose a user's home directory is the following: # ls -ld /home/foo drwxr-xr-x 3 foo users 4096 Oct 4 13:28 foo and the respective /var/mail: # ls -ld /var/mail/foo - -rw------- 1 foo mail 0 Oct 4 23:45 /var/mail/foo In the old server when the user tried to create a new test imap folder (from an imap client), then the newly created file would be: # ls -l /home/foo/ - -rw------- 1 foo users 0 Oct 2 02:08 test This is the desired behavior. In the new dovecot 2.1 server the following file permissions will apply: # ls -l /home/foo/ - -rw-r--r-- 1 foo users 0 Oct 2 02:08 test I finally noticed that if I chmod the /home/foo to 711, then the new file will have the desired (600) permissions. So, I can make a umask for the new users (login.defs), but that doesn't sound a pretty solution. Do you have anything else to suggest? If you need any .conf file, let me know.

Dovecot writing to mailbox user@domain
by John Oliver 06 Oct '14

centOS 6.5, dovecot-2.0.9-7.el6_5.1.x86_64 This is frustrating, because I had it working before... I could deliver an email to a user user@domain, then connect to dovecot IMAP and see the mail, no problem! Then I was told we had to use cyrus, and I was dealing with it for a few weeks. Now we're back to dovecot, and the last backup I had of that config has postfix delivering mail to /var/vmail/username as I want and expect, but dovecot looks for and creates /var/vmail/user@domain which I DON'T want [joliver@test ~]$ dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4 auth_username_format = %Lu mail_access_groups = mail mail_location = maildir:/var/vmail/%u/Maildir mail_privileged_group = mail mbox_write_locks = fcntl passdb { driver = pam } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocols = imap ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } userdb { args = uid=504 gid=505 home=/var/vmail/%u driver = static } [joliver@test ~]$ cat /etc/dovecot/dovecot-ldap.conf.ext hosts = localhost auth_bind = no ldap_version = 3 debug_level = 0 default_pass_scheme = SSHA base = ou=Users,dc=test,dc=com scope = subtree pass_filter = (&(objectClass=user)(uid=%u)) pass_attrs = mail=user,userPassword=password -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

How best to confirm that dovecot LDA logging is working correctly?
by Ben Johnson 06 Oct '14

06 Oct '14

Hello! I've posted to the list several times about a strange issue I'm having with dovecot LDA. When dovecot-lda is called in the context of a pipe script that is executed as the "vmail" user via the Dovecot Antispam plugin, dovecot-lda exits prematurely with status code 134. The dovecot deliver manual at http://wiki2.dovecot.org/LDA#logging states very clearly, "If dovecot-lda fails to write to log files it exits with temporary failure." That's a curious note, because I believe that a "temporary failure" exit code may be what I'm dealing with here. When I drag an email from Inbox to SPAM to trigger Antispam, I see only this (and no further output beyond the last line) in syslog, which is the configured logging destination for LDA: imap: antispam: mailbox_is_unsure(Junk): 0 imap: antispam: mailbox_is_trash(INBOX): 0 imap: antispam: mailbox_is_trash(Junk): 0 imap: antispam: mail copy: from trash: 0, to trash: 0 imap: antispam: mailbox_is_spam(INBOX): 0 imap: antispam: mailbox_is_spam(Junk): 1 imap: antispam: mailbox_is_unsure(INBOX): 0 imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 imap: antispam: running mailtrain backend program /bin/bash imap: antispam: running mailtrain backend program /bin/bash imap: antispam: running mailtrain backend program parameter 1 /usr/local/bin/sa-learn-pipe.sh imap: antispam: running mailtrain backend program parameter 2 --spam By contrast, if I "su" to the "vmail" user and call the LDA executable with the same arguments that my pipe script does, I see all of the expected output in syslog, AND the message is delivered successfully: /usr/lib/dovecot/deliver -d "sa-training(a)localhost.com" -m "Training.SPAM" -p "/tmp/sendmail-msg-25169.txt" lda: Debug: Loading modules from directory: /usr/lib/dovecot/modules lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib10_quota_plugin.so lda: Debug: Module loaded: /usr/lib/dovecot/modules/lib90_sieve_plugin.so lda: Debug: auth input: sa-training(a)localhost.com home=/var/vmail/localhost.com/sa-training mail=maildir:/var/vmail/localhost.com/sa-training/Maildir uid=5000 gid=5000 quota_rule=*:storage=0B sieve=/var/vmail/localhost.com/sa-training/.sieve lda: Debug: Added userdb setting: mail=maildir:/var/vmail/localhost.com/sa-training/Maildir lda: Debug: Added userdb setting: plugin/quota_rule=*:storage=0B lda: Debug: Added userdb setting: plugin/sieve=/var/vmail/localhost.com/sa-training/.sieve lda(sa-training(a)localhost.com): Debug: Effective uid=5000, gid=5000, home=/var/vmail/localhost.com/sa-training lda(sa-training(a)localhost.com): Debug: Quota root: name=user backend=dict args=:file:/var/vmail/localhost.com/sa-training/.quotausage lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=* bytes=0 messages=0 lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=Trash bytes=+104857600 messages=0 lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=Junk ignored lda(sa-training(a)localhost.com): Debug: Quota rule: root=user mailbox=INBOX bytes=+104857600 messages=0 lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=no command=quota-reached 100 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (95%) messages=0 reverse=no command=quota-warning 95 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (80%) messages=0 reverse=no command=quota-warning 80 sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=yes command=quota-below below sa-training(a)localhost.com localhost.com lda(sa-training(a)localhost.com): Debug: Quota grace: root=user bytes=0 (10%) lda(sa-training(a)localhost.com): Debug: dict quota: user=sa-training(a)localhost.com, uri=file:/var/vmail/localhost.com/sa-training/.quotausage, noenforcing=0 lda(sa-training(a)localhost.com): Debug: maildir++: root=/var/vmail/localhost.com/sa-training/Maildir, index=, indexpvt=, control=, inbox=/var/vmail/localhost.com/sa-training/Maildir, alt= lda(sa-training(a)localhost.com): Debug: Quota root: name=user backend=dict args=:file:/var/vmail//raw mail user/.quotausage lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=no command=quota-reached 100 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (95%) messages=0 reverse=no command=quota-warning 95 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (80%) messages=0 reverse=no command=quota-warning 80 raw mail user lda(sa-training(a)localhost.com): Debug: Quota warning: bytes=0 (100%) messages=0 reverse=yes command=quota-below below raw mail user lda(sa-training(a)localhost.com): Debug: Quota grace: root=user bytes=0 (10%) lda(sa-training(a)localhost.com): Debug: dict quota: user=raw mail user, uri=file:/var/vmail//raw mail user/.quotausage, noenforcing=0 lda(sa-training(a)localhost.com): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt= lda(sa-training(a)localhost.com): Debug: Destination address: sa-training(a)localhost.com (source: user@hostname) lda(sa-training(a)localhost.com): Debug: sieve: Pigeonhole version 0.4.2 initializing lda(sa-training(a)localhost.com): Debug: sieve: include: sieve_global_dir is not set;

the implication seems to be that dovecot-lda is crashes immediately, before it can log anything, when it's triggered via Antispam. Is there some way to determine what's happening? I've posted coredump and trace information previously, and nobody replied. Thanks for any help! -Ben

Hi dovecot guru.. I need some help configuring shared folder in my server.. This is the situation: DOVECOT 2.0.19 with POSTFIX - CLAMAV - AMAVISD - SPAMASSASSIN This is the production server and sharing folder between user work.. But i need some explanation.. 1) It's possible to share only a subfolder (E.G. => .INBOX.ESTERO) without share the main folder .INBOX? 2) Which is the best way (or best practice) to manage the dovecot-acl and dovecot-acl-list file?? Actually, i modifiy the dovecot-acl by hand (vi editor). but every time i modify it i need to restart the dovecot server to apply the configuration. And i need to reset the /var/run/dovecot/dict owner and group cause with dovecot restart the file go back in root:root owner - group Thank's in advance. Gianluca

v2.2.14.rc1 released
by Timo Sirainen 06 Oct '14

06 Oct '14

http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz http://dovecot.org/releases/2.2/rc/dovecot-2.2.14.rc1.tar.gz.sig I've wanted to do this release for months now, but I keep being too busy all the time. This release fixes several important bugs and a lot of smaller ones. Because there are such a large number of changes I thought I'd make this release candidate release first and the final v2.2.14 early next week. I usually read through the Dovecot mailing list mails before making a new release to see if there are some (important) bugs reported, but I've been way too busy recently to read through everything. I still have over 250 unread mails and I don't think I'll have time to read them anytime soon. On the positive side the Dovecot company is now hiring more people. Especially having more Dovecot coders would reduce my work load and maybe allow me to go back to reading the Dovecot mailing list daily.. See: http://www.dovecot.fi/dovecot-is-hiring-software-engineer-helsinki/ (you can do this work anywhere - no need to live in Finland) http://www.dovecot.fi/dovecot-is-hiring-operations-and-support-engineer-hel… (this probably requires living in Finland) http://www.dovecot.fi/dovecot-is-hiring-technical-pre-sales-engineer-helsin… (probably no need to live in Finland) Here are some of the larger changes since v2.2.13: * lmtp: Delivered-To: header no longer contains <> around the email address. Other MDAs don't have it either. * "Out of disk space" errors are now treated as temporary errors (not the same as "Out of disk quota"). * replication plugin: Use replication only for users who have a non-empty mail_replica setting. + lmtp proxy: Log a line about each mail delivery. + Added login_source_ips setting. This can be used to set the source IP address round-robin from a pool of IPs (in case you run out of TCP ports). + Rawlog settings can use tcp:<host>:<port> as the path. + virtual plugin: Don't keep more than virtual_max_open_mailboxes (default 64) number of backend mailboxes open. + SSL/TLS compression can be disabled with ssl_options=no_compression + acl: Global ACL file now supports "quotes" around patterns. + Added last-login plugin to set user's last-login timestamp on login. + LDAP auth: Allow passdb credentials lookup also with auth_bind=yes - IMAP: MODSEQ was sent in FETCH reply even if CONDSTORE/QRESYNC wasn't enabled. This broke at least old Outlooks. - passdb static treated missing password field the same as an empty password field. - mdbox: Fixed potential infinite looping when scanning a broken mdbox file. - imap-login, pop3-login: Fixed potential crashes when client disconnected unexpectedly. - imap proxy: The connection was hanging in some usage patterns. This mainly affected older Outlooks. - lmtp proxy: The proxy sometimes delivered empty mails in error situations or potentially delivered truncated mails. - fts-lucene: If whitespace_chars was set, we may have ended up indexing some garbage words, growing the index size unnecessarily. - -c and -i parameters for dovecot/doveadm commands were ignored if the config socket was readable. - quota: Quota recalculation didn't include INBOX in some setups. - Mail headers were sometimes added to dovecot.index.cache in wrong order. The main problem this caused was with dsync+imapc incremental syncing when the second sync thought the local mailbox had changed. - doveadm backup didn't notice if emails were missing from the middle of the destination mailbox. Now it deletes and resyncs the mailbox.

X-sieve-redirected-from
by Bob Miller 05 Oct '14

Hi, I am chasing a problem with sieve vacation messages. the sieve file looks like this: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["copy","vacation"]; # rule:[computerisms.ca] if anyof (address :contains "To" "bob.miller(a)ctfn.ca", address :contains "Cc" "bob.miller(a)ctfn.ca") { redirect :copy "bob(a)computerisms.ca"; vacation :days 66 :subject "autotest" "hello back"; } The mail is forwarded, but no vacation response is sent, and the mail is not forwarded. I find the lda error like this: _discarding_vacation_response_for_implicitly_delivered_message; _no_known_(envelope)_recipient_address_found_in_message_headers_ (recipient=<bob.miller(a)hostname.domain.tld>,_and_no_additional_ `:addresses'_are_specified) I am presuming this is the source of my problem. I am not sure why the domain is being modified to reflect the fqdn of the mail server host. When I look at the delivered mail, I find the following two headers: X-sieve-redirected-from: bob.miller(a)hostname.domain.tld Delivered-to: bob.miller(a)domain.tld I have been looking for a while now, and I can't figure out where it is picking up the hostname from. doveconf -a | grep hostname comes up empty. the hostname is not in any of the mta config files. Anyone got a hint? -- Computerisms Bob Miller 867-334-7117 / 867-633-3760 http://computerisms.ca

Dovecot does not update maildirsize after expunge
by Király Balázs 04 Oct '14

Hello, At the first, sorry for my englishJ I have a problem with dovecot quota since i migrated from courier. Dovecot does not update the Maildirsize after expunge, and the user running out of his quota very quickly. I checked, the file is deleted from the filesystem. If i delete the Maildirsize file, dovecot regenerate it with the correct datas when a new mail arrive. Also tried to set mail_debug=yes, but it doesnt show anything in the log, when delete mails. Im using NFS as homedirs, i tried to turn off the releated options in configuration, but didnt help. Has anyone any idea how to fix this issue? Thank you!

Configure antispam plugin with private namespaces

When I use antispam plugin <http://wiki2.dovecot.org/Plugins/Antispam> with a folder that is outside a namespace, the plugin works great.

Thunderbird ignores some folders
by dovecot.pkoch＠dfgh.net 03 Oct '14

03 Oct '14

Dear readers we are using Dovecot 2.2.7 and all of our users are using Thunderbird as their mail client. Some of them additionally use their iPad/iPhone and a very few an Android Mail-Client. Now one user noticed that two of his mail folders disappeared. He first believed that he accidentally deleted those folders but then he realized that they are still visible from his iPad. I checked this users maildir and everything looks normal. Deleting the index-files made no difference: New index-files were created but those two folders are still invisable from Thunderbird. My main concern is to find the reason for this behaviour. Maybe folders of other users have disappeared and they have not yet noticed. A fresh installation of Thunderbird will most likely fix this single users problem, but I cannot do this for all of our users. So here's my question: How would I debug such a situation? Kind regards Peter Koch And here's our config file: # Dovecot configuration file default_process_limit = 2048 protocols = imap listen = * base_dir = /var/dovecot/ mail_location = maildir:/mail/%u:LAYOUT=fs ssl_cert = </etc/ssl/certs/naev+chain.crt ssl_key = </etc/ssl/private/naev.key ssl_ca = </etc/ssl/certs/naev-ca.crt ssl_verify_client_cert = yes ssl_cert_username_field = x500UniqueIdentifier auth_ssl_username_from_cert = yes service imap-login { inet_listener imap { port = 0 } } service auth { client_limit = 4096 } service anvil { client_limit = 5000 } passdb { driver = checkpassword args = /usr/dovecot/bin/checkpassword } userdb { driver = passwd override_fields = home=/mail/%u } protocol imap { mail_max_userip_connections = 1000 }

LDA randomly failing to write email to disk
by Andy Dills 03 Oct '14

03 Oct '14

We're using 2.2.13 with pigeonhole 0.4.3, in a clustered environment (maildir on netapp, dual dovecot instances where each server is both a proxy and a backend). Every now and then (once a month per user, maybe?), users will see a blank email in their inbox. Investigating further, and we will see that the only information recorded in the maildir file for the message is the Return-Path, the Delivered-To, and the first Received line (the one generated by the local LDA via LMTP). For example, here is what I found in one such email today: Return-Path: <xxx(a)xecu.net> Delivered-To: <yyy(a)xecu.net> Received: from mail5.xecu.net ([10.0.1.85]) by mail2.xecu.net (Dovecot) with LMTP idX86eBjgaI1RdyQAA3SxDBg for <yyy(a)xecu.net>; Wed, 24 Sep 2014 15:24:20 -0400 Everything past that is lost, as if the either the LDA on mail2 exited early or was never sent the information from the dovecot instance on mail5. Here is a little more detail from the header of the same email, different recipient (all other recipients received the email properly, only one failed to receive properly): Return-Path: <xxx(a)xecu.net> Delivered-To: <yyz(a)xecu.net> Received: from mail5.xecu.net ([10.0.1.85]) by mail1.xecu.net (Dovecot) with LMTP id KPh8ItMXI1StBAAA/c3zFg for <yyz(a)xecu.net>; Wed, 24 Sep 2014 15:24:20 -0400 Received: from mail5.xecu.net by mail5.xecu.net (Dovecot) with LMTP id QsUBFoQZI1RjhgAAXyr1JQ ; Wed, 24 Sep 2014 15:24:20 -0400 Received: from mail5.xecu.net (localhost [127.0.0.1]) by mail5.xecu.net (Postfix) with ESMTP id 30AAE323BB18; Wed, 24 Sep 2014 15:24:20 -0400 (EDT) ... This is what I see in the logs of mail2, which is where the failure happened: Sep 24 15:24:20 mail2 dovecot: lmtp(51549, yyy(a)xecu.net) X86eBjgaI1RdyQAA3SxDBg: sieve: msgid=unspecified: stored mail into mailbox 'INBOX' When I look at the logs of mail1, which is where the successful delivery happened: Sep 24 15:24:20 mail1 dovecot: lmtp(1197, yyz(a)xecu.net) KPh8ItMXI1StBAAA/c3zFg: sieve: msgid=<20140924192412.1435.qmail(a)xxx.xecu.net>: stored mail into mailbox 'INBOX' Nothing of note seems to be logged on mail5 (only a message from postfix, nothing from the proxy side of the lmtp). I do notice, when I check for the PID of 51549 in the logs, all of its other transactions seem to register with proper msgids and were delivered fine. Also, I notice plenty of other messages that have the msgid=unspecified error, but which were delivered with no problems and not truncated, so I'm suspecting what may be happening is that somehow the backend instance is not receiving the actual data portion, and only getting the envelope from proxy instance. How do I approach debugging this? It's very infrequent, but yet quite annoying. Seems to have started since we upgraded to 2.2.13 (from an older 2.1 build) earlier this year. Thanks, Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---

GETMETADATA UTF8 encoding of folder names instead of UTF7

home from SQL
by Ralf Hildebrandt 03 Oct '14

03 Oct '14

Currently I'm using user_query = SELECT 1000 AS uid, 1000 AS gid, '/srv/vmail/%2.256Hu/%Lu' AS home, ... so I'm hashing based on %u (basically). But in my SQL db I have a "unique_identifier" field, which never changes, even when the user is changing his/her email address (due to marriage or the like). What I'd really like to do is to use %u to find the value of the unique_identifier field, hash THAT value and use "AS home". But how? That way I can rename users without shuffling directories around the filesystem. -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

Re: [Dovecot] quota using wrong limits in user shared mailboxes
by Bartłomiej Nogaś 03 Oct '14

03 Oct '14

Hi, I confirm this bug with LDAP userdb. The temporary workaround is to set quota ignore rule for Shared namespace or specific shared folder. This is obviously not secure workaround. Example: for a shared namespace: namespace ( .... prefix = Shared Folders/%%u/ ... } you have to set quota_rule4 = Shared Folders/*:ignore or quota_rule4 = Shared Folders/username/*:ignore - Bartlomiej Nogas

Trouble getting listescape plugin to work with "$" separator (as demonstrated in Wiki) in Dovecot 2.2.9
by Ben Johnson 03 Oct '14

03 Oct '14

Hello, I'm attempting to install the listescape plugin so that IMAP users are able to include periods (.) and forward slashes (/) in IMAP directory names. I'm following the instructions at http://wiki2.dovecot.org/Plugins/Listescape , which imply that this can be accomplished by enabling the listescape plugin and using the dollar sign ($) as the separator. With regard to my dovecot configuration, first, I changed protocol imap { mail_plugins = quota imap_quota antispam } to protocol imap { mail_plugins = quota imap_quota antispam listescape namespace private { separator = $ inbox = yes } } When I start dovecot, I receive the following error: doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:102: namespace private {} has been replaced by namespace { type=private } Pretty straightforward; I made the required change to yield protocol imap { mail_plugins = quota imap_quota antispam listescape namespace { type = private separator = $ inbox = yes } } But now, when I attempt to start dovecot, I receive the following error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 104: Unknown variable: $ doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 104: Unknown variable: $ Is it possible that the instructions at the Wiki 2 URL cited above are out-of-date? If I try to escape the $ with any other character (I'm just shooting in the dark regarding possible escape characters, as I cannot find definitive documentation that pertains to escaping $ in the dovecot configuration), I receive yet another error: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Namespace '': Hierarchy separator must be only one character long doveconf: Error: managesieve-login: dump-capability process returned 89 doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Namespace '': Hierarchy separator must be only one character long Ultimately, I have two questions: 1.) Is the nesting structure that I've employed correct?

auth with entire email addr instead of just username
by Cliff Hayes 02 Oct '14

02 Oct '14

I am trying to configure a new IMAP based mail server. I thought I had everything correct. I have dovecot logging turned up and see that dovecot is processing the entire email address as the username like this... Oct 2 14:52:20 servername dovecot: auth: Debug: pam(testuser(a)domain.com,1.2.3.4): lookup service=dovecot ... and of course pam is reporting that as an invalid user. Moments ago when all was mbox, authentication worked fine. I can see Thunderbird has the username correct (no domain). What is tacking on the domain and how do I fix? Thanks in advance.

two dovecot instances
by jjhoffart 02 Oct '14

02 Oct '14

Hello, I am currently trying to setup two invocations of dovecot to run on a debian based server. One for director and the other a stock debian instance. The issue I am having is when I go to start the director instance, I receive multiple errors telling me that the listening ports are already in use. I have change these ports in the 10-master.conf file but am still presented with the same errors when starting the second instance. Is this the only file in which the ports need to be changed (10-master.conf) or is there another file in which the ports need to be set?

Simply mysql quota check
by Alfredo Saldanha 02 Oct '14

02 Oct '14

Hi there, I'm setting up a new email server with Dovecot(2.2.9) and MySQL. My Dovecot configuration: #/etc/dovecot/conf.d/90-quota.conf service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = dovecot unix_listener quota-warning { user = vmail } } plugin { quota = maildir:User quota quota_warning = storage=95%% quota-warning 95 %u@%d quota_warning2 = storage=80%% quota-warning 80 %u@%d args = /etc/dovecot/dovecot-sql.conf.ext } #/etc/dovecot/dovecot-sql.conf.ext password_query = \ SELECT username AS user, value AS password \ FROM mailboxes WHERE username = '%n@%d' user_query = \ SELECT username, domain, \ CONCAT('*:storage=', SUBSTRING_INDEX(quota, 'm', 1)*1048576) AS userdb_quota_rule \ FROM mailboxes, domains WHERE mailboxes.username = '%n@%d' \ AND domains.domain = '%d' My idea is when a message is delivered, the dovecot to check quota in the mysql according to the value received in the "user_query" but he does not. It shows a value of 2GB that I don't know where it gets. I execute a manual query in mysql to know the quota my test user and checked that are 5GB, but when I see the dovecot, it shows 2G. SELECT username, domain, CONCAT('*:bytes=', SUBSTRING_INDEX(quota, 'm', 1)*1048576) AS userdb_quota_rule FROM mailboxes, domains WHERE mailboxes.username = 'junix(a)domain.com' AND domains.domain = 'domain.com' +-------------------+----------------+--------------------+ | username | domain | userdb_quota_rule | +-------------------+----------------+--------------------+ | junix(a)domain.com | domain.com | *:bytes=5242880000 | +-------------------+----------------+--------------------+ $ sudo doveadm quota get -u junix Quota name Type Value Limit % User quota STORAGE 10 2097152 0 User quota MESSAGE 1 - How would the setting to simply verify the quota of users as userdb_quota_rule this query?

Master user and invalid credentials dovecot-2.2.13
by Götz Reinicke - IT Koordinator 30 Sep '14

30 Sep '14

Hi, I followed the docs from the dovecot wiki (http://wiki2.dovecot.org/Authentication/MasterUsers) and still have some problem: 1. uncommented "!include auth-ldap.conf.ext" in 10-auth.conf 2. htpasswd -b -c -s .... to create user/password for a masteruseruser 3. checked auth-master.conf.ext When I try to test the login, I always get an "invalid credentials" in the logs with auth_debug=yes set. dovecot can read /etc/dovecot/master-users The users are in ldap. The example wiki shows the passwords {SHA1}...., in my password file they are {SHA}.... The "master user" posting in september gave some clues what might be wrong, but did not help to solve my problem. Any suggestions are welcome! Thanks and regards.

No AUTH PLAIN with dovecot 2.0.19
by Michael Wechner 30 Sep '14

30 Sep '14

Hi I have installed the package dovecot-postfix on Ubuntu 12.04 LTS: dovecot --version: 2.0.19 postconf -d | grep version: 2.9.6 and receiving email works very fine, but relaying email does not work. I think the problem is that after STARTTLS the authentication is not being executed 250-AUTH PLAIN 250-AUTH=PLAIN which means using telnet returns telnet mx2.wyona.com 587 Trying 50.116.54.197... Connected to node3.wyona.com. Escape character is '^]'. 220 node3.members.linode.com ESMTP Postfix (Ubuntu) EHLO letscallitevil.com 250-node3.members.linode.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN So far I have used dovecot version 1.2.9, which works very fine, but the configuration /etc/dovecot/dovecot.conf seems to be very different in the case of dovecot version 2.0.19. I have checked all kind of tutorials for several days now, like for example https://help.ubuntu.com/10.04/serverguide/postfix.html but nothing helped. Any pointers or help is very much appreciated. Thanks Michael

"doveadm sync/backup" and SSH should use "ssh-agent" if available
by Jesus Cea 30 Sep '14

I use SSH-AGENT in my system, to cache SSH credentials and avoid typing my key every time I connect to a remoto host.

"doveadm backup/sync" are badly documented
by Jesus Cea 29 Sep '14

29 Sep '14

Most documents around there talk abour "dsync", but the modern way is "doveadm backup". This command is not documented in the wiki and there are a few details missing, like how to use it thru SSH. I am currently doing some tests about how to backup my mdbox. I can do tests in local using: $ doveadm backup -u jcea -m proveedores/dovecot mdbox:/tmp/aa/ This will "backup" this mailing list mailbox to "/tmp/aa". Good. Lets try thru SSH: $ doveadm backup -u jcea -m proveedores/dovecot ssh 127.0.0.1 dsync -u jcea mdbox:/tmp/aa/ jcea(a)127.0.0.1's password: Fatal: Invalid parameter: mdbox:/tmp/aa/ dsync-local(jcea): Error: read(remote) failed: EOF (version not received) How shoudl I do it?. $ doveadm backup -h backup: invalid option -- 'h' doveadm backup [-u <user>|-A] [-S <socket_path>] [-dfR] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] <dest> I can't find any explanation at all about the different parameters of "doveadm backup".

"doveadm backup/sync" don't follow message moving even with MDBOX
by Jesus Cea 29 Sep '14

29 Sep '14

Using mdbox as the storage backend, moving a message from a mailbox to another just update a reference. The message is not fisically moved on the disk. I would expect "dsync" to use this fact when source and destination are mdbox. But it doesn't. Anybody else can confirm?. Any plan to implement it?. Thanks!. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

dsync full sync
by Atıf CEYLAN 29 Sep '14

29 Sep '14

Hi all, I have 2 question. First: I use dovecot (version 2.2.9) with mdbox mail format. When I run dsync tool with "mirror" or "backup" parameters my source and destination directory synchronize correctly but if I delete some messages in user mailbox, deleted messages does not synced to destination. For example : atif(a)domain.com path is /mail/domain.com/atif/ and its size is 1GB. after first running the "dsync -u atif(a)domain.com backup mdbox:/backup/domain.com/atif/" command, size of "/backup/domain.com/atif/" is 1GB I deleted 300mb messages in atif mailbox then /mail/domain.com/atif/ is decreased to 700MB and I launched dsync command again. But /backup/domain.com/atif/ is not decreased to 700Mb. My backup directory still 1GB . I tried dsync with "-f , backup, mirror" parameters. Second problem, the first time the backup atif's quota size is increasing to x2. before backup : atif(a)domain.com quota size 1GB after backup: atif(a)domain.com quota size 2GB so I must run "doveadm quota recalc" command. Why? What is correct usage of mdbox mail format and dsync tool? -- M.Atıf CEYLAN

dsync mirror does not maintain changes between mailboxes
by Alan McGinlay 28 Sep '14

28 Sep '14

Hi, running: dsync -D -v -o mail_fsync=never mirror -R -f -u user@domain imapc: Where "domain" is a cyrus imap server does not do what the documentation says it does, not even close. After the first run to an empty mailbox on the dovecot 2.2.13 server all the mails (1.1GB) seem to be correctly synced. I send a test email to the dovecot server and it shows up correctly. Second run of the above dsync command, first thing that happens is all mails are deleted from the dovecot mailbox (yet the storage used by output of "du -m" doesn't change) and the sync appears to happen again from scratch however the disk space increases again! Now up to about 2GB and another run will take it up a few hundred mb more! I have tried with multiple different mail storage formats, maildir++, mdbox sdbox, all show the same (except maildir which just complains that INBOX can't be deleted on the second dsync run). This is frustrating beyond belief, please please anyone who has any insight let me know, the dsync debug output is a little huge to sanitize and post to the list but i can send it individually if anyone has any ideas! I am ready to give up totally on dovecot but at the same time I just wish it would work! doveconf -n # 2.2.13 (6bb26098a45c): /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-67-virtual x86_64 Ubuntu 14.04.1 LTS auth_debug = yes auth_master_user_separator = * default_vsz_limit = 512 M disable_plaintext_auth = yes imapc_features = rfc822.size imapc_host = oldmailhost.domain.com imapc_master_user = cyradmin imapc_password = xxxxxxxx imapc_user = %u mail_gid = vmail mail_home = /var/vmail/domains/%d/%1n/%n mail_location = sdbox:~/sdbox mail_plugins = zlib notify quota fts fts_solr mail_prefetch_count = 30 mail_uid = vmail mailbox_list_index = yes managesieve_sieve_capability = fileinto imapflags namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = separator = / } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes pass = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ quota = dirsize:User quota quota_grace = 10%% quota_rule = *:storage=20G sieve = ~/.dovecot.sieve sieve_dir = /var/vmail/sieve/domain/%1d/%d/%1n/%n/ sieve_extensions = imapflags fileinto zlib_save = bz2 zlib_save_level = 5 } protocols = imap pop3 lmtp sieve service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0666 user = vmail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } vsz_limit = 512 M } service imap { process_limit = 1024 vsz_limit = 512 M } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } verbose_ssl = yes protocol lmtp { mail_plugins = zlib notify quota fts fts_solr quota sieve } protocol imap { mail_plugins = zlib notify quota fts fts_solr imap_quota } protocol sieve { managesieve_implementation_string = Cyrus timsievd v2.2.13 }

Dovecot Sieve and Postfix header_checks Issue
by Klaipedaville on Google 27 Sep '14

27 Sep '14

Hello List, I tried to subscribe but it's taking forever for the confirmation email to arrive so I thought I would ask away by emailing directly. My apologies in advance should this question appear twice. It may seem real simple to experts but I cannot really figure it out. I'll try to be concise: Dovecot version is 2.1.7. Its dovecot –n is real short one and follows right after my question. I have my Postfix 2.9.6 properties set like this: header_checks = /etc/path/to/myfile. Then I have Dovecot Sieve also configured and working fine. Now the trouble is that these two cannot be combined together can they? Dovecot Sieve and Postfix's header_checks? If I turn off header_checks in Postfix then Dovecot Sieve is working fine. If I vise versa turn off Dovecot Sieve then Postfix's header-checks are also working fine. However, when I keep them both turned on it also works but only partially and in this case Dovecot Sieve never bounces back any rejected massages remotely, the bounce happens only locally. That is I can see it in my logs that it was rejected locally but the message is never sent back to the sender saying something like, "Spam is rejected here". Thus the reject turns into a silent discard without telling the sender anything at all. Any ideas, help, advices how do I fix that? Would be really grateful for any suggestions / assistance at all. Many thanks in advance! P.S. I would like to use both because Dovecot Sieve is a very powerful and great plugin that uses Spamassassin's added tags and headers based on which I create my rules. Postfix in its turn has a very neat feature of checking the headers via regexp but Postfix does not see / detect Spamassassin's added headers at all because I passed delivery and authentication (which is a way better than Postfix's) to dovecot deliver. # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.6 ext4 auth_mechanisms = plain login cram-md5 scram-sha-1 auth_verbose = yes hostname = WindTalker info_log_path = /var/log/dovecot-sieve.log log_path = /var/log/dovecot-sieve-errors.log mail_location = maildir:/home/mvail/%d/%n 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 passdb { args = /etc/dovecot/passwd driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_default = /etc/dovecot/default.sieve sieve_dir = ~/sieve } pop3_uidl_format = %g 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 } } ssl_ca = </etc/ssl/ca.crt ssl_cert = </etc/ssl//new.crt ssl_key = </etc/ssl/new.key userdb { args = uid=vmail gid=vmail home=/home/vmail/%u driver = static } protocol lda { mail_debug = yes mail_plugins = sieve } Regards, Dennis.

ALT storage question

I want to migrate from a non-hashed storage to a hashed storage. So I set this up: mail_location = mdbox:/srv/vmail/%2.256Hu/%Lu/mdbox:ALT=/srv/vmail/%Ld/%Ln/mdbox I rsynced the "old" mdbox-style mailbox from another machine to to /srv/vmail/%Ld/%Ln/mdbox (/srv/vmail/charite.de/ralf.hildebrandt/mdbox in my case) The mail_location /srv/vmail/c5/ralf.hildebrandt(a)charite.de was non-existing.

Thanks for confirming what I suspected, Timo. The latter, if it is at all feasible, appears to be an "inside job" type of exploit, where the exploiter already has an account but can arbitrarily change their password. It's not as serious as the pre-login one, but worth addressing if the narrow circumstances of using post-login bash scripts apply. Joseph Tam <jtam.home(a)gmail.com>

Re: director
by Chris Lasater 26 Sep '14

26 Sep '14

The configuration and run/base_dir directories can be where ever you like. The locations Eduardo stated are the most appropriate for dovecot installed with an RPM. Mine were compiled and set in the home directory, so they are in a slightly different location. As long as you use the -c to point to the correct configuration file you should be good. For mine I kept my dovecot config file in the default location and put the director one elsewhere and created an alias, so that I can start the director by just typing director. This might make things easier for you to manage, then you can just stop it by running "doveadm -i <instance_name> stop" alias director="sudo -E PATH=${PATH} LD_LIBRARY_PATH=${LD_LIBRARY_PATH} /home/user/dovecot/sbin/dovecot -c /home/user/dovecot/etc/dovecot/director.conf" On 09/23/2014 05:00 PM, jjhoffart wrote: >> Thanks for the replies, >> I am still fairly new to dovecot and still learning.

Log shows following error: """ Initialization failed: namespace configuration error: list=yes requires prefix=yes to end with separator """ relevant part from dovecot-sql.conf.ext: """ user_query = \ SELECT \ 1002 AS uid \ , 1003 AS gid \ , CONCAT('/www/home/vmail/domains/', SUBSTRING(d.name, 1, 1), '/', d.name, '/', u.username) AS home \ , namespace_prefix AS 'namespace/default/prefix' \ , 'yes' AS 'namespace/default/inbox' \ , '%s' AS 'mail_service' \ FROM vm_domain d \ INNER JOIN vm_user u ON u.vm_domain_id = d.id \ WHERE d.name = '%d' AND u.username = '%n' AND u.active = 1 AND d.active = 1 """ namespace_prefix can be empty or INBOX. doveconf -n output: """ # 2.2.13: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.3-RELEASE amd64 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no listen = * mail_debug = yes mail_location = maildir:~/Maildir mmap_disable = yes namespace default { inbox = yes list = yes location = prefix = separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size mail_log_group_events = no } service imap { process_limit = 1480 } ssl_cert = </usr/local/etc/ssl/server.crt ssl_key = </usr/local/etc/ssl/server.key.unsecure userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } verbose_proctitle = yes protocol imap { imap_capability = IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE mail_max_userip_connections = 900 } protocol pop3 { mail_max_userip_connections = 300 } """ Seems like "prefix = " is interpreted as "prefix = yes".

Is dovecot vulnerable to the shellshock/CVE-2014-6271 exploit?
by Joseph Tam 26 Sep '14

26 Sep '14

I'm right now handling this beach-ball sized grenade, and trying to figure out which of our services need to be locked down right away. Since dovecot passes values via environment variables based on user input (e.g. username, password, mailbox?) to auxilliary executables (including possibly bash shell scripts), is dovecot vulnerable to this exploit? (This is not a fault of dovecot, but rather bash's inadequate handling of environment variables.) For example, injection of this sort 1 LOGIN (){x;}exploit-code whatever I guess auth_username_chars would mitigate this particular attempt (assuming it can work), but other values such as mailbox names could also be injected post authentication. Can someone with working knowlegde of dovecot's internals confirm/deny whether this is a something that needs to be addressed? Joseph Tam <jtam.home(a)gmail.com>

How to configure dovecot imap to listen on multiple ports?
by Rick Thomas 26 Sep '14

26 Sep '14

I need my dovecot imap server to listen on ports 143, 993, and also 30143 and 30993. What syntax do I use in (I presume) the /etc/dovecot/conf.d/10-master.conf file to do this? Thanks! Rick

Does dovecot work OK on *BSD?
by Steve Litt 26 Sep '14

26 Sep '14

Hi all, I have a dovecot server on my Debian Wheezy desktop computer. My days with Debian are limited, and I'm investigating several 'BSD's: OpenBSD FreeBSD PCBSD NetBSD DragonflyBSD etc Is there any reason Dovecot wouldn't work on any of those? Does anyone know if those OS's have packages for Dovecot, or do I need to compile it myself? Thanks, SteveT Steve Litt * http://www.troubleshooters.com/ Troubleshooting Training * Human Performance

Confusing wording on the wiki
by Alan McGinlay 24 Sep '14

24 Sep '14

Hi, I am confused by the wording of this Wiki entry: sieve = ~/.dovecot.sieve The path to the user's main active Sieve script. When ManageSieve is used, this is a symbolic link pointing to the active script in the sieve_dir directory. Avoid placing the active Sieve script inside the sieve_dir directory. So this should be a link *to* the active script in the sieve_dir directory however the active script shouldn't actually be in that directory???? http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration Confused :S /A
