[Dovecot] migrating mailboxes on dovecot
by Spyros Tsiolis 25 Mar '12

25 Mar '12

Hello all, I want to ask about something I never did before. I have a dovecot/XMail/LAMP/Horde installation on a CentOS 5.5 32-bit system with two domains : domainA and domainB All the users used to have their mailboxes on domainA. However the personell dept decided that 90% of the users will have to have their mailboxes set to domainB and the other 10% will stay at domainA. So, I need to migrate those mailboxes from domainA to domainB. The only thing is I haven't done that ever. The directory structure is : "/var/MailRoot/domains/domainX/Username/Maildir/" and under there the usual suspects : cur (directory) dovecot.index.cache (file) dovecot-keywords (file) dovecot-uidvalidity (file) new (directory) tmp (directory) dovecot.index (file) dovecot.index.log (file) dovecot-uidlist (file) dovecot-uidvalidity.4cc055c6 (file) subscriptions (file) Using dovecot v1.2.15 Any help would be appreciated. Iam supposed to do this today !! :-) Thank you all, s. ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] sysconfdir depreacted
by Noel Butler 25 Mar '12

25 Mar '12

The purpose of any build scripts --sysconfdir is to tell the configuration to build in a path for its binaries configuration file(s). Dovecot 2.1.3, seems to insist that that directory is now /etc/dovecot/ ignoring --sysconfdir=/etc as in 1.2.x and previous majors before that, is this a bug? if not, then I see no point of sysconfdir any more and it should be removed, if dovecot deliberately ignores what it is told to use.

[Dovecot] dovecot and cloudfile systems
by jackie sparks 24 Mar '12

24 Mar '12

I'm trying to store mailboxes in a cloudfile system and I am running into alot of problems using courier, between time skew, file locking and cache creation problems. I was wondering if dovecot has any problems using maildirs across a limited fuse file system. I cant lock files, This is accessed using the fuse library. I thought taking out the standard checking for return values would be a work around because everything imap daemon is doing can be done from a shell by hand except filelocking and setting times on files. I am doing this on Rack Spaces cloud files. This is something that not many if any are doing. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-= This e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C.

Re: [Dovecot] kernel problem in RedHat? -- RH specific, or what linux kernels does this affect?
by Linda Walsh 24 Mar '12

24 Mar '12

Is this redhat's version of the kernel only? Or does it apply to other linux kernels and other distros? Any idea what linux kernel versions might cause this? (from main dovecot webpage news) Thu Mar 22 14:38:53 EET 2012 Red Hat/CentOS users: A recent kernel update <https://bugzilla.redhat.com/show_bug.cgi?id=681578> causes Dovecot to start failing after it has reached 1000 child processes. To fix this, downgrade your kernel until Red Hat releases a fixed kernel.

[Dovecot] Advice for new dovecot / imap proxy? setup
by Luca Lesinigo 23 Mar '12

23 Mar '12

Hello list. I'm planning a new mail servers for our company's customers to replace the oldish Courier-IMAP based one, we already started to deploy some mail accounts on a dovecot-2.0 server as an early test. I'd like to implement the new system with dovecot-2 (I'll probably go straight to dovecot-2.1.x) and I'd like to get it right from the beginning so I'm here asking for some advice. The issue I'm investigating right now is how to manage a single IMAP / POP / SMTP / webmail "entry point" for multiple mail servers... in other words an IMAP proxy. It would be desirable for multiple reasons: - graceful migration from the current system: we'd make the mailserver hostname point to the proxy (along with its SSL certificates) and then the proxy would route each domain to the correct IMAP non-ssl server on our LAN. No need to update customer's systems configuration and we can move one domain at a time from the old to the new server, behind the scenes - be ready for similar migrations in the future (eg. right now we're still keeping the imap servers with the qmail MTA, but we'd like to switch to postfix+dovecot in the future) - be ready for sharding mail domains on multiple IMAP servers (if/when current hardware reach its capacity or needs to be swapped out for new gear) - be ready to serve traffic over IPv6 without touching our precious mailbox servers - isolate the mailbox servers from direct external access and just run IMAP on them, let other systems run ssl, pop3, smtp, webmail, etc... Ideally the 'proxy' system would run dovecot imap and pop3 (SSL protected) and Roundcube webmail (PHP, on https) and just speak IMAP to the underlying mail servers on our internal LAN. We'd like to support all the recent IMAP goodies to make modern users happy (IMAP IDLE, LEMONADE, etc) and possibly implement Maildir quota on the new backend mailbox server to improve our operations (currently we just run du in a cronjob once a day on the current mailserver, IMAP clients including the webmail do not know about quota and thus cannot show amount of free space). In addition to that, customer's will hit the SMTP server running on that 'proxy' system and this is good to keep its configuration separated from the SMTP server of the actual mail servers (which has a different configuration and is restricted to get connections only from our MX systems and not from outside sources). I'd like to know if that plan sounds reasonable or if there's something stupid in it. Also, is the proxy going to support all kind of IMAP stuff of the backend server (IDLE, CONDSTORE, Maildir quota, immediate notification of IDLE clients thanks to linux inotify, etc...) or will it limit me somehow? thanks, -- Luca Lesinigo

[Dovecot] Dovecot 2.1.3 Proxy creates mailbox on proxy
by Ed Nitido 23 Mar '12

23 Mar '12

Hey all, I've upgraded from a working Dovecot 2.0.17 Proxy with a master user setup to Dovecot 2.1.3 and I've merged my conf settings from 2.0.17 into 2.1.3. I'm able to start up dovecot proxy and telnet localhost, however it creates the users home director on the proxy server instead of going to the backend dovecot server (which has already been successfully upgraded to 2.1.3 from 2.0.17). In my old 2.0.17, I had the entire namespace section commented out in 10-mail.conf. To achieve the same in 2.1.3 I had to remove the file 15-mailboxes.conf, otherwise my error log would have the following if I just commented out the namespace section and left that file in place: *Error: user edward(a)dev.domain.com: Initialization failed: namespace configuration error: inbox=yes namespace missing* *Error: Invalid user settings. Refer to server log for more information.* So now I'm trying to figure out why the proxy doesn't get the mail server IP from director, when doveadm has the backend server listed *# doveadm director status* *mail server ip vhosts users* *192.168.12.205 100 0* Can anyone see something I've missed?

[Dovecot] dovecot 2.1.3 dsync Unexpected finish reply
by Micah Anderson 23 Mar '12

23 Mar '12

I've been moving users from one system to another by doing a dsync mirror operation. The first dsync mirror takes some time, because of the number of users involved, so I am doing an initial sync, and then I direct the users to the new location and do a final 'freshening' sync to get any changes that happened during the longer sync. The problem seems to be with this freshening sync, it seems quite fragile breaking with things like: dsync-local(user(a)example.com): Error: msg-get failed: box=Spam uid=3034

[Dovecot] Dovecot 2.1.3 on solaris with mysql - make fails
by Robert Hartzell 21 Mar '12

21 Mar '12

I'm trying to build 2.1.3 on solaris 11 11/11 with gcc 4.5.2 & sun studio 12.2 & 12.3 CPPFLAGS="-I/opt/openssl/include -I/usr/mysql/include/mysql" \ LDFLAGS="-L/opt/openssl/lib -L/usr/mysql/lib/mysql -R/opt/openssl/lib:/usr/mysql/lib/mysql" \ ./configure --prefix=/opt/dovecot \ --sysconfdir=/etc/opt \ --with-ssl=openssl \ --with-mysql make fails with both solaris standard openssl and my build of openssl. I'm also getting the same error using sunstudio mysql version is 5.1.37 The relevant output of make is on pastebin http://pastebin.com/aALHG0yL I have seen some reference to this with google but nothing thats very recent and no solutions. Anyone know how to get past this? Any tips on building dovecot on solaris? Pointers would be much appreciated. -- Robert

Hello, excuse me but there is some documentation about replication now? I dont' understand where i must put the lines below (dovecot.conf? , 20-imap?) Excuse but it's not so clear for me cause i'm a new dovecot user. Another question, i use virtual users on mysql backend , so for replication i need to give ssh at every virtual users? Or i can use a only use a system ssh user? Thank's service aggregator { # give enough permissions for mail processes fifo_listener replication-notify-fifo { user = vmail mode = 0600 } unix_listener replication-notify { user = vmail mode = 0600 } } service replicator { # start replication at startup process_min_avail = 1 } plugin { # host1 replicates to host2 mail_replica = remote:vmail at host2.example.com # host2 replicates to host1 #mail_replica = remote:vmail at host1.example.com } #dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} service doveadm { # if you're using a single virtual user, set this to # start ssh as vmail (not root) user = vmail } -- Rispetta l'ambiente: se non ti è necessario, non stampare questa mail. ****************************************** Ing.

hi my system is a centos 5 with qmailtoaster i migrated my email server with around 5000 users from dovecot version 1.2 to version 2 i have two separate 2 tb hdd's storing webmail data of these users. the load on the server goes very high over 100 during peak load times and the imap connections get dropped frequently, webmail becomes very slow. however pop3 download works ok in the dovecot log file i get errors as such Warning: Maildir /homebackup/domains/xxxx/xxxx/Maildir/.ALL_INBOX MAIL: Synchronization took 71 seconds (20 new msgs, 0 flag change attempts, 0 expunge attempts) i had configured dovecot 1.2 using source but i had installed version 2 using qmailtoaster rpm i am a bit confused as to what settings are to be done for a very busy server note that the cpu system usage and ram usage are less but IO wait goes to around 80-90 percent can you please guide me or post some dovecot version 2 config file settings that are relevant to a busy server. rajesh

[Dovecot] mdbox and pop3 locking
by Ken A 21 Mar '12

21 Mar '12

With mdbox, what does dovecot lock when "pop3_lock_session(pop3): yes"? Specifically, I'm wondering if Dovecot LDA is able to deliver mail when a session is locked, if using mdbox, or if it will tempfail until the session is unlocked? Thanks, Ken -- Ken Anderson Pacific Internet - http://www.pacific.net

[Dovecot] auth tcp socket, Authentication client gave a PID 7542 of existing connection
by Alex Ha 21 Mar '12

21 Mar '12

Hi Dovecot-list! My setup consists of a dovecot server with lmtp delivery and 3 postfix mta servers in front. Previously the mtas authenticated (SASL) through the courier-authdaemond software to our mysql database. To get support for more password formats i migrated to dovecot for SASL authentification. Our postfix mtas connect to dovecot through a tcp-socket smtpd_sasl_auth_enable = yes smtpd_sasl_type = dovecot smtpd_sasl_path = inet:10.11.100.230:12345 smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = broken_sasl_auth_clients = yes 10.11.100.230 is our dovecot server. Please look at the attached doveconf.log to see my auth service configuration. I did the configuration according to the postfix SASL README. http://www.postfix.org/SASL_README.html#server_dovecot I tested the setup and everything worked fine but after 2 days i noticed these error messages in my mail.log: dovecot: auth: Error: BUG: Authentication client gave a PID 7542 of existing connection and also these messages from postfix: SASL LOGIN authentication failed: Connection lost to authentication server I get the dovecot error message about 3000 times a day and postfix message about 270 times. Please see my attached mail.log for a detailed trace. Thank you for your help :) Alex

[Dovecot] bug uni_utf8_str_is_valid(vname)
by Jernej Porenta 20 Mar '12

20 Mar '12

Heya, We are expiriencing issues with dovecot 2.1.1 on Linux with weird filenames in home directory of username. We are using mbox IMAP folders, with no special changes (mail_location = mbox:~/:INBOX=%h/.mailbox). Mar 6 13:37:17 machine dovecot: imap(username): Panic: file mail-storage.c: line 628 (mailbox_alloc): assertion failed: (uni_utf8_str_is_valid(vname)) Mar 6 13:37:17 machine dovecot: imap(username): Error: Raw backtrace: /opt/dovecot-2.1.1/lib/dovecot/libdovecot.so.0 [0x2ba41cb79450] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot.so.0 [0x2ba41cb794a6] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot.so.0 [0x2ba41cb78963] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot-storage.so.0 [0x2ba41c87ebd5] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot-storage.so.0 [0x2ba41c88c12c] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot-storage.so.0(fs_list_iter_next+0x1b4) [0x2ba41c88c494] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot-storage.so.0 [0x2ba41c885342] -> /opt/dovecot-2.1.1/lib/dovecot/libdovecot-storage.so.0(mailbox_list_iter_next+0x234) [0x2ba41c885604] -> dovecot/imap [0x40b2d1] -> dovecot/imap(cmd_list_full+0x520) [0x40c1f0] -> dovecot/imap(cmd_list+0xb) [0x40c3eb] -> dovecot/imap(command_exec+0x37) [0x410427] -> dovecot/imap [0x40f4cd] -> dovecot/imap [0x40f582] -> dovecot/imap(client_handle_input+0x3f) [0x40f6cf] -> dovecot/imap(client_input+0x62) [0x410052] -> /opt/dovecot Mar 6 13:37:17 machine dovecot: imap(username): Fatal: master: service(imap): child 20873 killed with signal 6 (core dumps disabled) The bug is reproducible by using home folder structure available from: http://bit.ly/x8pTXS AFAIK, the problem lies in processing the file list of home folder, which can contain filenames that do not have proper UTF-8 encoding of filenames, which causes dovecot to crash. On the other hand, UTF-8 filenames created on the system by hand (using touch), are not displayed in IMAP LIST command (sample is included in the folder structure; single letter file).

[Dovecot] dovecot, sieve and vacation
by Cedric Jeanneret 20 Mar '12

20 Mar '12

Hi there ! Have a small problem with sieve and vacation: it seems to descard the vacation filter I created instead of sending back an email: Mar 20 11:56:28 hostname dovecot: deliver(virtual_user): sieve: msgid=unspecified: discarding vacation response for message implicitly delivered to <virtual_user@hostname> after searching a bit on the net, I stumbled on another (old) thread: http://www.mail-archive.com/dovecot@dovecot.org/msg25955.html I'm not really sure it's the same problem, as I'm sending the mail from another host (via telnet, for testing purpose). Other sieve rules (such as flagging, moving and so on) work fine. Only vacation is crapy. Here's the roundcube generated rule: require ["vacation"]; if true { vacation :days 2 "on holidays!"; } Any help welcome :) Cheers, C.
