[Dovecot] problems when using dsync between servers
by Yann Dupont 08 Dec '11

08 Dec '11

Hello, I'm trying to migrate from maildir++ to mdbox. The maildir++ is a leftover of our previous setup (was using courier) We have 3 virtuals servers for our +70000 accounts. Now, I'd like to use mdbox, so I'm trying using dsync for that. I setup a new virtual server, configured for mdbox. 1st, I tried a basic setup: I established a file with all my accounts (taken from LDAP) and then I use this script : FILENAME=$1 while read LINE do dsync -u $LINE backup $LINE@my_new_server done < $FILENAME But it's quite slow and dsync hangs. So I tried another approach using multi threaded python. Much faster (using all the cores), but dsync still hangs on some accounts. After a certain time dsync exit with an error like that : Panic: file dsync-worker-local.c: line 1688 (local_worker_save_msg_continue): assertion failed: (ret == -1) dsync-remote(E072184L): Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(+0x3fd8a) [0x7f34fc577d8a] -> /usr/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x32) [0x7f34fc577e72] -> /usr/lib/dovecot/libdovecot.so.0(i_error+0) [0x7f34fc55119f] -> dsync() [0x40ff0b] -> dsync() [0x410142] -> dsync(dsync_worker_msg_save+0x99) [0x40f639] -> dsync() [0x40e24a] -> dsync() [0x40d8ef] -> dsync() [0x40dbfc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x48) [0x7f34fc5830d8] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x9f) [0x7f34fc58403f] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x28) [0x7f34fc583068] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f34fc5713a3] -> dsync(main+0x9e1) [0x4078b1] -> /lib/libc.so.6(__libc_start_main+0xfd) [0x7f34fbde9c4d] -> dsync() [0x406cf9] This is on a RUNNNING server. My aim was to make some pass on the running server, then stop it and make a last pass to finish the process. Is dsync supposed to run only on a stopped server ? Is my approach totally wrong ? -- Yann Dupont - Service IRTS, DSI Université de Nantes Tel : 02.53.48.49.20 - Mail/Jabber : Yann.Dupont(a)univ-nantes.fr

[Dovecot] sql dict: commit failed: MySQL server has gone away
by Mark Zealey 08 Dec '11

08 Dec '11

Following on from this thread: http://www.dovecot.org/list/dovecot/2010-September/052704.html <https://owa2010.webfusion.com/owa/redir.aspx?C=a447887e3d204944a8c766142df4…> in 2.0.16 I am seeing the same issues. I believe this would be related to some timeouts set on our mysql servers which are pretty low (30 or 60 seconds or so to drop idle connections). This is happening for imap, pop and lmtp processes when they try to update quotas stored in a mysql database; presumably it is the dict process that actually has these issues - the lmtp delivery isn't lasting longer than 1 second so shouldn't be seeing any timeouts there. This is always followed by the "Error: dict quota: Quota update failed, it's now desynced" line; presumably it is telling the truth but I'm not sure how I could tell. We are also seeing this "MySQL server has gone away" issue in login processes but it isn't causing an issue there as presumably dovecot transparently retries rather than just giving up as it seems to in the quota updates. Any thoughts or advice would be appreciated. Mark

[Dovecot] POP3/IMAP crash signal 10
by Patrick Wood 08 Dec '11

08 Dec '11

Hi, I'm building a Postfix/Dovecot mail server and while I am able to send/receive emails using telnet, after establishing a connection to Dovecot via a client (Mail Live, Thunderbird etc) the following appears in the logs: Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3-login: Login: user=<user(a)domain.com>, method=PLAIN, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx, mpid=282 78 Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.error] master: Error: service(pop3-login): child 28277 killed with signal 10 (core not dumped - set service pop3-log in { drop_priv_before_exec=yes }) Nov 28 14:11:02 mailserver dovecot: [ID 583609 mail.info] pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/5, size=3250 I also experience very poor connectivity to the server, with Microsoft Mail and Thunderbird regularly failing to connect (connection errors in the client and no login attempt in the dovecot logs). I assume this is related to the issue above. I am running dovecot 2.0.16 on Solaris 10 SPARC using a ZFS filesystem for mailbox storage.

Hopefully someone can see something I'm missing

Maybe all users on backend-server1 are fetching their mails causing high load while backend-server2 is idle. Is it possible to specify more than one backend-server IPs as I can do for the database hosts for userdb queries?

[Dovecot] lazy_expunge plugin and folder subscription trouble

Hello, I wanted to test the lazy expunge plugin together with mdbox. It seems to me that the folder subscriptions file in the mdbox directory was overwritten with only a few folder names every time I added or removed something in the list of subscribed folders, or even if I turned the imap folder subscription feature off and on.

[Dovecot] doveadm fetch vs search+fetch
by Joseph Tam 08 Dec '11

08 Dec '11

What's the pactical difference between using "doveadm fetch" rather than using "doveadm search" in conjunction with "doveadm fetch", as the man pages suggest? It seems "doveadm fetch" functionally supercedes "doveadm search" making the latter obsolete. It can even be closely simulated with "doveadm -f tab fetch ... 'mailbox-guid uid' search-query ...".

[Dovecot] IMAP SPECIAL-USE extension
by Timo Sirainen 07 Dec '11

07 Dec '11

It's implemented now in dovecot-2.1 hg. It also deprecates autocreate plugin (but it still works the old way). The idea is that you can now do e.g.: mailbox Trash { auto = no special_use = \Trash } mailbox Drafts { auto = no special_use = \Drafts } mailbox Sent { auto = subscribe # autocreate, autosubscribe special_use = \Sent } mailbox Spam { auto = create # autocreate, but don't autosubscribe special_use = \Junk } mailbox virtual/All { # if you have a virtual "All messages" mailbox auto = no special_use = \All } The mailbox names require a namespace prefix, so if you use e.g. "INBOX." prefix you'll need to use: mailbox INBOX.Trash { ..etc..

[Dovecot] master user only for sieve

Changes in SOGo is forcing me to define a master user, so that SOGo can disable sieve out-of-office processing on a given date. I'm not too happy about having master users that are allowed to read the users messages, so is it possible to define a master user that can only log in trough manage-sieve? -jf

But for solving the localization problem for special-use folders, it's only half the way.

[Dovecot] MS Exchange IMAP Proxy
by Terry Carmen 06 Dec '11

06 Dec '11

I need to make the IMAP interface of an Exchange 2000 server available on the net, however I would like to give it a little protection, and believe Dovecot's IMAP proxy might be appropriate. Does anybody have a *really simple* config that would allow IMAP pass-through to a single Exchange server? The examples I've seen all assume some sort of load balancing, which isn't an issue here, so I'd like to eliminate the need for an unnecessary database server. Does Dovecot do any cleanup of the IMAP commands that would be useful in protecting Exchange (from this, http://www.cvedetails.com/cve/CVE-2007-0221/ for example), or am I barking up the wrong tree? If Dovecot isn't helpful for this, can anybody point me to a better resource? Thanks! Terry

[Dovecot] Strange quota problem

I have a strange problems with quota on v2.0.14. We have an ldap user directory, and all users should have a mailQuota defined there. My problem is that some users gets the quota enforced, while others don't, and "doveadm user" doesn't seem to agree with "doveadm quota ge gett" Ref: $ doveadm user janfrode(a)example.net userdb: janfrode(a)example.net home : /usr/local/atmail/users/j/a/janfrode(a)example.net mailQuota : quota_rule=*:storage=2100000 $ doveadm -f tab quota get -u janfrode(a)example.net Quota name Type Value Limit % UserQuota STORAGE 760 1000000 0 UserQuota MESSAGE 62 - 0 Why limit 1000000 instead of 2100000 ? $ doveadm user omar(a)example.net userdb: omar(a)example.net home : /usr/local/atmail/users/o/m/omar(a)example.net mailQuota : quota_rule=*:storage=1000000 $ sudo doveadm -f tab quota get -u omar(a)example.net Quota name Type Value Limit % UserQuota STORAGE 0 - 0 UserQuota MESSAGE 0 - 0 $ doveadm user testkunde(a)example.net userdb: testkunde(a)example.net home : /usr/local/atmail/users/t/e/testkunde(a)example.net mailQuota : quota_rule=*:storage=1000000 $ doveadm -f tab quota get -u testkunde(a)example.net Quota name Type Value Limit % UserQuota STORAGE 33918 - 0 UserQuota MESSAGE 137 - 0 Why no storage limit ?

[Dovecot] Dovecot crash non stop: "uid 0: exited on signal 11"

Hi all, I have an old physical freebsd 6.2 server running Dovecot 1.0.7. I wanted to virtualised it. So, I did a dd from the physical server and then I restored it on then now Virtual Machine. I booted the server, all services are running just fine excepted Dovecot. I tried to investigate the log as much as I can but i'm not getting any usefull pieces of information. The only entries I have in the log files are the following: /*log: /var/log/messages:*/ /Dec 5 09:53:35 hostname kernel: pid 33815 (imap), uid 0: exited on signal 11 Dec 5 09:53:39 hostname kernel: pid 33820 (imap), uid 0: exited on signal 11 Dec 5 09:54:22 hostname kernel: pid 33910 (pop3), uid 0: exited on signal 11 Dec 5 09:55:22 hostname kernel: pid 34071 (pop3), uid 0: exited on signal 11 Dec 5 09:55:47 hostname kernel: pid 34103 (imap), uid 0: exited on signal 11 Dec 5 09:56:13 hostname kernel: pid 34143 (pop3), uid 0: exited on signal 11 Dec 5 09:56:21 hostname kernel: pid 34164 (pop3), uid 0: exited on signal 11 Dec 5 09:56:26 hostname kernel: pid 34180 (imap), uid 0: exited on signal 11 Dec 5 09:56:40 hostname kernel: pid 34201 (imap), uid 0: exited on signal 11 Dec 5 09:56:49 hostname kernel: pid 34227 (imap), uid 0: exited on signal 11/ /*log: /mail/log/dovecot.log:* dovecot: Dec 05 10:13:46 Info: imap-login: Login: user=<test-amaury(a)mydomain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured dovecot: Dec 05 10:13:46 Error: child 36621 (imap) killed with signal 11/ I'm also running a squirrelmail as a webmail and here when I refresh a folder content 3/5 times I'm getting an error: /Error: Connection dropped by IMAP server Query: SELECT "INBOX.Corbeille"/ I'm using Dovecot version 1.0.7 on a freebsd 6.2 and my dovecot.conf is: dovecot -n /# 1.0.7: /usr/local/etc/dovecot.conf base_dir: /mail/ log_path: /mail/log/dovecot.log protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /mail//login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_greeting: POP3/IMAP ready. verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: maildir:~/Maildir fsync_disable: yes maildir_copy_with_hardlinks: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota trash mail_plugins(imap): quota imap_quota trash mail_plugins(pop3): quota mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: default_realm: tropik.nc passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: sql args: /usr/local/etc/dovecot-sql.conf socket: type: listen master: path: /mail/auth-master mode: 384 user: vmail group: vmail plugin: quota: maildir trash: /usr/local/etc/dovecot-trash.conf/ Thank you for your help!

[Dovecot] Questions about single intance storage
by Maria Arrea 03 Dec '11

03 Dec '11

Hello We are using dovecot 2.0.16 with mdbox+zlib. We are now testing SiS (Single Instance Storage) and I have 5 questions: 1º Is possible to "dedup" existing mdboxes? 2º Are attachments compressed with zlib if mdboxes already use zlib? 3º I have plenty CPU to spare, should I use a low value of mail_attachment_min_size , like 16KB ? 4º Can I "undo" SiS if I have problems? 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Thank you for your (great) support. Maria

[Dovecot] lda/sieve ignores quota from ldap
by Jens Meißner 03 Dec '11

03 Dec '11

Hello, I'm using Dovecot 2.0 with Sieve as MDA and Postfix as MTA. The Postfix delivery command is /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a "$RECIPIENT". I have set a default quota with quota_rule = *:storage=1G. Some users should have a larger quota. This is defined in a ldap directory and I have set user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid,mailQuota=quota_rule=*:storage=%$. The imap_quota plugin shows the right quota for all users but the lda ignores the quota rule from ldap. If a user is over default quota but not over his ldap defined quota I get the following error message: From: Mail Delivery Subsystem <postmaster@[…]> Your message to <[…]> was automatically rejected: Quota exceeded (mailbox for user is full) The log file shows the following: Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full) Nov 30 18:21:17 […] dovecot: lda([…]): Error: sieve: script /var/mail/[…]/dovecot.sieve failed with unsuccessful implicit keep (user logfile /var/mail/[…]/dovecot.sieve.log may reveal additional details) Nov 30 18:21:17 […] dovecot: lda([…]): msgid=<20111130172116.7F065A07D@[…]>: rejected: Quota exceeded (mailbox for user is full) dovecot.sieve.log: error: msgid=<20111130172116.7F065A07D@[…]>: failed to store into mailbox 'INBOX': Quota exceeded (mailbox for user is full).

[Dovecot] can not get t'bird to create folder
by sean darcy 02 Dec '11

02 Dec '11

dovecot-2.0.16 on Fedora 15. thunderbird-8.0 I can access dovecot from thunderbird, imap maildir. But when I try to create a new folder, nothing happens. I'm not using LAYOUT=fs, so I have added, tb-extra-mailbox-sep, which didn't seem relevant anyhow. Any help appreciated. sean
