[Dovecot] Login process connection routing
by Brandon Davidson 20 Jul '10

20 Jul '10

Timo, Just out of curiosity, how are incoming connections routed to login processes when run with: service imap-login { service_count = 0 } I've been playing with this on our test director, and the process connection counts look somewhat unbalanced. I'm wondering if there are any performance issues with having a single process handle so many connections. It seems fine (system load is actually lower than with service_count = 1), but I thought I'd ask. /usr/sbin/dovecot \_ dovecot/imap-login \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login \_ dovecot/imap-login [5 connections (5 TLS)] \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login [4 connections (4 TLS)] \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login [1 connections (1 TLS)] \_ dovecot/imap-login [315 connections (315 TLS)] \_ dovecot/imap-login [63 connections (63 TLS)] \_ dovecot/imap-login [12 connections (12 TLS)] \_ dovecot/imap-login \_ dovecot/imap-login [10 connections (10 TLS)] \_ dovecot/imap-login [2 connections (2 TLS)] \_ dovecot/imap-login [370 connections (370 TLS)] \_ dovecot/imap-login [24 connections (24 TLS)] -Brad

[Dovecot] Doveadm director flush/remove
by Brandon Davidson 20 Jul '10

20 Jul '10

I've got a couple more issues with the doveadm director interface: 1) If I use "doveadm director remove" to disable a host with active users, the director seems to lose track of users mapped to that host. I guess I would expect it to tear down any active sessions by killing the login proxies, like I'd done 'doveadm direct add HOSTNAME 0 && doveadm director flush HOSTNAME' before removing it? Here's what I see with an active open connection: [root@cc-popmap7 ~]# doveadm director status brandond Current: 10.142.0.179 (expires 2010-07-14 01:26:14) Hashed: 10.142.0.179 Initial config: 10.142.0.161 [root@cc-popmap7 ~]# doveadm director remove 10.142.0.179 [root@cc-popmap7 ~]# doveadm director status brandond Current: not assigned Hashed: 10.142.0.174 Initial config: 10.142.0.161 2) "doveadm director flush" returns the wrong usage: [root@cc-popmap7 ~]# doveadm director flush doveadm director remove [-a <director socket path>] <host> 3) "doveadm director flush" all breaks the ring: [root@cc-popmap7 ~]# doveadm director flush all Jul 14 01:26:33 cc-popmap7 dovecot: director: Error: Director 10.142.0.180:1234/right disconnected Jul 14 01:26:33 cc-popmap7 dovecot: director: Error: Director 10.142.0.180:1234/left disconnected Jul 14 01:26:33 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/left): Invalid HOST-FLUSH args Jul 14 01:26:33 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/right): Invalid HOST-FLUSH args For some reason, flushing a host address only disconnects one side: [root@cc-popmap7 ~]# doveadm director flush 10.142.0.160 Jul 14 01:28:23 cc-popmap7 dovecot: director: Error: Director 10.142.0.180:1234/right disconnected Jul 14 01:28:23 oh-popmap7 dovecot: director: Error: director(10.142.0.162:1234/left): Invalid HOST-FLUSH args -Brad

[Dovecot] [dovecot] Dovecot Migration so far
by Mark Moseley 20 Jul '10

20 Jul '10

We've been doing our own beta testing of Dovecot 2.0-beta4 IMAP (both direct IMAP and webmail-fronted), and we've had nothing but glowing compliments from our beta users/victims. I've also been running a lone box with the latest mercurial build and that's been running just fine too. All mail data is on NFS, but I've put indexes on the local disk, which has worked just dandy so far. Everything's been great and all I've seen amiss are a few random problems -- all of which are are barely impacting us and I mention only for the sake of feedback. All boxes are Debian Lenny i386, running 2.6.33.1. One oddity is that I see lots of messages like this (I've obfuscated paths/IPs/usernames, so assume paths are all actually correct) for a variety of different mailboxes prior to their indexes directory getting initially created: Apr 02 13:25:24 imap(mail@box): Error: creat(/var/tmp/Indexes/14/75/mail(a)box/dovecot.mailbox.log) failed: No such file or directory Judging by the mtimes of the containing directories, the directory was created a couple of seconds after the error gets logged, so I'm guessing mailbox_log_alloc is just getting called too early. It obviously just happens that first time. Doesn't seem to actually be hurting anything, that I can tell. One other kind of weird thing I saw was that originally I had my indexes on a dedicated partition with ext4 (Debian Lenny, i386, 2.6.33.1), I was seeing scattered messages like this: Mar 29 18:02:38 imap(mail@box): Error: FETCH [] for mailbox INBOX UID 3244 got too little data: 1116 vs 1087383 Mar 29 18:02:38 imap(mail@box): Error: Corrupted index cache file /var/tmp/Indexes/12/dc/mail(a)box/.INBOX/dovecot.index.cache: Broken virtual size for mail UID 3244 The message corresponding with UID 3244 was around 1116 bytes (+32 bytes, IIRC), so no clue where the 1087383. In all the cases of that error I saw, the lefthand number of bytes was very closer to correct and the righthand was way way off, and the S= flag in the filename was correct too. I'm guessing that the random righthand number was just due to corrupted cache. When I reformatted that partition as ext3, the error went almost completely away (just a few total over the past few days, as opposed to a few per hour when it was on ext4). I don't even have an educated guess as to why that'd happen. A wild guess would be that ext4's delayed allocation was causing problems. Even under ext4, it was still pretty rare and only, say, 1 out of 100 imap logins. And ext3 performance on the indexes partition so far has been just fine, so I don't plan on switching back to ext4 -- though if anyone has any experience with putting indexes on reiserfs and/or xfs versus ext3, I'd love to hear your thoughts. I've also seen a couple of these in the past few days (on beta4, not repo version -- haven't been running repo version long enough to say if it'd do the same): Mar 31 21:52:54 imap(mail@box): Error: fdatasync(/mail/username/mail@box/Maildir/dovecot-uidlist) failed: Input/output error Mar 31 21:52:54 imap(mail@box): Error: Raw backtrace: /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0 [0xb77c0b71] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0 [0xb77c0bef] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(i_error+0) [0xb77c0ea8] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_begin_to+0x9a9) [0xb7837ca9] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(mail_index_sync_begin+0x56) [0xb7837d56] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_sync_index_begin+0x51) [0xb78734d1] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0 [0xb78716eb] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_storage_sync_force+0x4d) [0xb78719bd] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_uidlist_lookup+0x96) [0xb7877646] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0 [0xb787215a] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_sync_index+0x7f0) [0xb78729d0] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0 [0xb78715b6] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(maildir_storage_sync_init+0x162) [0xb7871b92] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot-storage.so.0(mailbox_sync_init+0x39) [0xb7815759] -> dovecot/imap [mail@box 215.108.28.102 UID](imap_sync_init+0x54) [0x805efa4] -> dovecot/imap [mail@box 215.108.28.102 UID](cmd_sync_delayed+0x223) [0x805f2a3] -> dovecot/imap [mail@box 215.108.28.102 UID](client_output+0xb6) [0x8056de6] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0 [0xb77d5d4a] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0xf5) [0xb77cd1d5] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(io_loop_run+0x30) [0xb77cc220] -> /opt/dovecot-2.0.beta4/lib/dovecot/libdovecot.so.0(master_service_run+0x2a) [0xb77b9e1a] -> dovecot/imap [mail@box 215.108.28.102 UID](main+0x1c5) [0x805f8e5] -> /lib/libc.so.6(__libc_start_main+0xe5) [0xb764d455] -> dovecot/imap [mail@box 215.108.28.102 UID] [0x804e621] Mar 31 21:52:54 master: Error: service(imap): child 4500 killed with signal 6 (core dumps disabled) In 4 days of beta testing with a fair number of users, I've seen maybe 4 of these backtraces total, so not exactly a big issue. These are all super minor things. Everything's been fantastic so far.

[Dovecot] About Logging
by Henrique Fernandes 20 Jul '10

20 Jul '10

It is possible to make dovecot do not log any request from a determined host? Because, we gonna use ldirectord for foward request and etc and the ldirectord makes an connecting every 2 seconds to find out if the server is ok, and also make a login in imap and pop3 to check this service as well. Is there any how to make dovecot do not log entries for a determined host ? The logs get too many info that we don need! Any ideias ? Thanks! * *i have sent a msg like this, but i got no answer i thought i might have not deliver into the mailist! I am sorry if it already have it!* *[]'sf.rique

[Dovecot] namespace trouble
by Kevin Faulkner 20 Jul '10

20 Jul '10

I am having some trouble with dovecot 1.2.12 and some namespace issues, or at least that's what I think is the issue. I setup a virtual mailhosting using mysql and postfix. I can receive email and send email without a problem, but when I use mutt to sign in to dovecot, I can't list any Folders, it see's INBOX but it doesn't see any mail. I generally try to not post my problems online, but I searched around on the Internet and I couldn't find anything similar to this issue. I also used kmail to connect to the and it is able to see the mail, but when I can't create any folders. mutt connecting option: mutt set spoolfile=imaps://server.here/INBOX." Here is the mutt debug (mutt -d 3) 4< a0001 OK Capability completed. 4< * LIST (\Noselect) "."

[Dovecot] Unable to get Dovecot LDA/deliver working
by Frank van Amsterdam 20 Jul '10

20 Jul '10

I want to setup Dovecot LDA, but I don't understand what I'm doing anymore. I have to note that I'm a Linux beginner. I've been trying now for several months and I'm about to give up. Till so far I'm having no result. :-( My current setup is done as described at http://www.linuxmail.info. We use Postfix 2.3.3 (with Postgrey, Spamassassin and ClamAV), Dovecot 1.2.11 and OpenLDAP 2.4.1 on CentOS 5.5. All incoming e-mail are delivered by Postfix in the users' maildir. We use this as a base for SOGo, our groupware solution and it runs smoothly. I have to setup a new mailserver, because we're standardising on Debian. My employer wants to have new functions like out-of-office-replies and forwarding. I want to make use of sieve. Unfortunately I don't know anyone who can help me. My problem is that I don't understand how the delivery process is working. I've read much documentation from Postfix and Dovecot, but I find it too difficult to understand. What do I understand? I know that I have to make changes in /etc/dovecot, /etc/postfix/main.cf and /etc/postfix/master.cf as described at http://wiki.dovecot.org/LDA. /etc/dovecot.conf # OS: Linux 2.6.18-028stab064.7 i686 CentOS release 5.5 (Final) reiserfs base_dir: /var/run/dovecot/ protocols: imap imaps pop3 pop3s managesieve ssl: no version_ignore: yes login_dir: /var/run/dovecot/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_executable(managesieve): /usr/libexec/dovecot/managesieve-login mail_location: maildir:/home/vmail/%u/Maildir 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_executable(managesieve): /usr/libexec/dovecot/managesieve 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 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): managesieve_logout_format(default): bytes=%i/%o managesieve_logout_format(imap): bytes=%i/%o managesieve_logout_format(pop3): bytes=%i/%o managesieve_logout_format(managesieve): bytes ( in=%i : out=%o ) lda: postmaster_address: postmaster(a)domain.nl mail_plugins: cmusieve mail_plugin_dir: /usr/lib/dovecot/lda deliver_log_format: msgid=%m: %$ -- FROM=%f SUBJECT=%s log_path: /var/log/dovecot-deliver.log info_log_path: /var/log/dovecot-deliver.log syslog_facility: mail sendmail_path: /usr/lib/sendmail rejection_subject: Rejected: %s rejection_reason: Your message to <%t> was automatically rejected:%n%r auth_socket_path: /usr/local/var/run/dovecot-auth-master auth default: mechanisms: plain login username_format: %Lu passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: static args: uid=500 gid=500 home=/home/vmail/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: sieve: /var/sieve-scripts/%u.sieve sieve_dir: %h/sieve sieve_global_dir: /var/lib/dovecot/sieve/global/ /etc/postfix/main.cf virtual_mailbox_domains = /etc/postfix/domains ## Plain text file with the domains virtual_mailbox_base = /home/vmail virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf virtual_alias_maps = ldap:/etc/postfix/ldap-groups.cf virtual_uid_maps = static:500 virtual_gid_maps = static:500 dovecot_destination_recipient_limit = 1 #virtual_transport = dovecot ## Commented out to deliver by Postfix /etc/postfix/ldap-users.cf server_host = localhost search_base = dc=domain,dc=com version = 3 query_filter = (&(objectclass=mailUser)(mail=%s)) result_attribute = uid result_format = %s/Maildir/ /etc/postfix/ldap-groups.cf server_host = localhost search_base = dc=domain,dc=com version = 3 query_filter = (&(objectclass=mailGroup)(mail=%s)) leaf_result_attribute = mail special_result_attribute = member /etc/postfix/master.cf dovecot unix - n n - - pipe flags=DRhu user=vmail:vmail argv=/usr/local/libexec/dovecot/deliver -d <username> I hope someone can help me, because many people on the internet say that it is easy.
