[Dovecot] dsync-local(user): Error: proxy client timed out
by Metro Domain Admin 05 Feb '13

05 Feb '13

Hello, I have an intermittent but frequent problem using dsync backup. The command outputs: dsync-local(user): Error: proxy client timed out Then dies with exit code 75. Any subsequent attempts to re-run the backup invariably fail like this: dsync-local(user): Warning: Destination mailbox INBOX has been modified, need to recreate it before we can continue syncing dsync-local(user): Error: read() from worker server failed: EOF dsync-local(user): Error: msg-copy returned invalid input: dsync-local(user): Error: remote: dsync-remote(user(a)domain.com): Error: Can't delete mailbox INBOX: INBOX can't be deleted. dsync-remote(l_user(a)domain.com): Error: command MSG-SAVE failed dsync-local(user): Warning: Mailbox changes caused a desync. You may want to run dsync again. The syntax I am using is: dsync -u $user backup \ ssh -i <idfile> <user@host> \ dsync -u l_$user We have this running in a script that loops through all users. The error happens mostly on the larger mailboxes but I've seen it succeed on the largest ones then fail on smaller. One mid-sized account now fails consistently. The backup is running from a Mac OS PPC server running 2.1.12 The target is a Linux Intel box running 2.1.13, but I had the same problem sending to a Mac OS Intel on 2.1.12. Mdbox in all cases. Thanks, Tony

According to the roadmap http://wiki2.dovecot.org/Roadmap implementation of the METADATA / ANNOTATE extensions is fairly high on the list. I was just curious if there is a target release in mind for this functionality?

[Dovecot] Overloading IMAP Server
by Harford, Ken 04 Feb '13

04 Feb '13

Hi All, I am having an issue with dovecot IMAP reading and writing to one specific mailbox. I have a check email delivery script that sends out a email and then logs into dovecot to check if the mailbox that the message has been delivered to. However, the servers that send these messages send them in bunches depending on how many postfix spools it is checking. So I could get 60 messages all being sent to 1 mailbox and then having to read that same mailbox to check if the message actually got delivered. I am using postfix as the MTA and dovecot is actually delivering the message to the mailbox I am getting a lot of errors such as the following: Could not connect to IMAP server imap failed: IMAP RECEIVE CRITICAL - Could not select INBOX Any ideas as to what I can tweak in dovecot to allow these messages to be verified. Thanks for any information or help you could provide!! Ken

[Dovecot] Reviewing end-user ham/spam submissions before feeding them to sa-learn via Dovecot Antispam plug-in
by Ben Johnson 02 Feb '13

02 Feb '13

Currently, I'm using the Dovecot Antispam plug-in with great success. Everything works as expected. However, I would like to change the plug-in's behavior such that it simply sends a copy of a message that is moved from Inbox -> Junk (or Junk -> Inbox) to an administrator, instead of calling sa-learn (I'm using SpamAssassin) automatically. Basically, I would like to be able to review messages that end-users submit for training before they are actually fed to sa-learn. Has anyone had a similar need? If the Antispam plug-in already supports this, if the necessary commands can simply be added to the shell script that Antispam calls, or if there is a better method altogether, any help is greatly appreciated. Thank you! -Ben

[Dovecot] Dovecot Director Doveadm fails when there are a lot of output information
by Ramon Frontera 01 Feb '13

01 Feb '13

Hi, we are running dovecot 2.1.13 We have 2 proxies with director and 4 mail servers. we use LDAP when we execute doveadm-quota -A and doveadm with few output lines, its works fine. When we use doveadm-search or doveadm-mailbox with a lot of output information the command stops the execution and the command no ends. The connection to one of the 4 mailserver has finished at this moment. I have made some tests and i have found that if we use only one mailserver the commands works fine. I put the gdm bt output hope it help you. (the proxy thats executes the command) (gdb) bt full #0 0x0000003872ee86f3 in __epoll_wait_nocancel () from /lib64/libc.so.6 No symbol table info available. #1 0x0000003873a534b8 in io_loop_handler_run (ioloop=0x2364120) at ioloop-epoll.c:181 ctx = 0x236b080 events = <value optimized out> event = <value optimized out> list = <value optimized out> io = <value optimized out> tv = {tv_sec = 59, tv_usec = 389208} msecs = 59390 ret = <value optimized out> i = <value optimized out> call = <value optimized out> #2 0x0000003873a52488 in io_loop_run (ioloop=0x2364120) at ioloop.c:398 No locals. #3 0x0000003873a3de43 in master_service_run (service=0x2363fd0, callback=<value optimized out>) at master-service.c:544 No locals. #4 0x0000000000413d6e in doveadm_server_flush_one () No symbol table info available. #5 0x0000000000414741 in doveadm_mail_server_user () No symbol table info available. ---Type <return> to continue, or q <return> to quit--- #6 0x000000000040e6bc in doveadm_mail_next_user () No symbol table info available. #7 0x000000000040ed7c in doveadm_mail_cmd () No symbol table info available. #8 0x000000000040f00c in doveadm_mail_try_run () No symbol table info available. #9 0x00000000004162b1 in main () No symbol table info available.

The error repeats at random intervals, I guess related to the activity.

[Dovecot] sieve_max_redirects=0 not working as documented
by Arnaud Abélard 31 Jan '13

31 Jan '13

Hello I'm trying to keep my users from using the "redirect" action with pigeonhole from dovecot 2.0.21. As documented in http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration I configured sieve like this: plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_max_redirects = 0 } (and doveconf indeed shows the new setting for sieve_max_redirects) Unfortunately I can still use the redirect action: lda(dummy(a)univ-nantes.fr): Debug: sieve: executing script from /vmail/d/u/dummy/.dovecot.svbin lda(dummy(a)univ-nantes.fr): sieve: msgid=<510A758D.1030305(a)univ-nantes.fr>: forwarded to <xxxx(a)xxxxx.com> what could I have missed?

[Dovecot] v2.1.14 released
by Timo Sirainen 31 Jan '13

31 Jan '13

http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.14.tar.gz.sig If you've been waiting for a fully stable release after the recent cache file troubles in v2.1.11+, this release should be the one. Hopefully there won't be v2.1.15 anytime in near future. (v2.2.rc1 does look close though.) BTW. I know there are quite a lot of mails I haven't replied to in dovecot list. Too busy for now.. + doveadm acl recalc command added - v2.1.11+ had a race condition where it sometimes overwrote data in dovecot.index.cache file. This could have caused Dovecot to return the same cached data to two different messages. - mdbox: Fixes to handling duplicate GUIDs during index rebuild
