[Dovecot] Director problems
by Joseba Torre 11 Jun '12

11 Jun '12

Hi, I've just setup a testing enviroment for director, and it's not working as expected. I have just 1 director (called director) and 2 dovecot servers (dovecot1 and dovecot2); these are exact copies. First problem: when both dovecot servers are up, every imap connection is redirected to the same server as you can see here: $ sudo doveadm director map user mail server ip expire time <unknown> 158.227.4.186 2012-06-06 13:34:12 <unknown> 158.227.4.186 2012-06-06 13:34:27 <unknown> 158.227.4.186 2012-06-06 13:34:34 (I don't know if that <unknown> is good or not) I've tried with 3 different users and ips to no change, users are always directed to the same host. Second problem: if I try to add/remove/modify one of the dovecot servers, the output of doveadm director map/status seems to be ok, but any new user connection fails with this log: Jun 6 14:51:59 director dovecot: director: Warning: Delaying new user requests until ring is synced Jun 6 14:52:27 director dovecot: director: Error: director: User test1 host lookup failed: Timeout - queued for 30 secs (Ring not synced for 73 secs) Jun 6 14:52:31 director dovecot: imap-login: Aborted login (auth failed, 1 attempts in 34 secs): user=<>, method=PLAIN, rip=158.227.4.186, lip=158.227.4.185, TLS, session=<Oyx9O83B/wCe4wS6> Any clue?

[Dovecot] multi-instance doveadm user -m woes
by David Warden 11 Jun '12

11 Jun '12

I'm having difficulty with the doveadm who command on a multi-instance setup of dovecot. When I run the who command on the non-standard instance with the -m flag (to see their mail location), this happens: [root@wardentest3 dovecot]# doveadm -i mailtest user -m warden doveadm(root): Error: user warden: Initialization failed: Namespace 'INBOX.': Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/root (try prefixing it with mbox: or maildir:) I tried adding my mail_location setting as location to both of my legacy and default namespaces, but got the same error. I also tried adding the -a flag like so: doveadm user -a /var/run/dovecot/mailtest/auth-userdb -m warden doveadm(root): Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Connection refused (the default instance is currently stopped) and combining -a and -i out of curiosity: [root@wardentest3 conf.d]# doveadm -i mailtest user -a /var/run/dovecot/mailtest/auth-userdb -m warden doveadm(root): Error: user warden: Initialization failed: Namespace 'INBOX.': Ambiguous mail location setting, don't know what to do with it: /var/spool/mail/root (try prefixing it with mbox: or maildir:) I have 2 instances, default and mailtest: [root@wardentest3 conf.d]# doveadm instance list path name last used running /var/run/dovecot/mailtest mailtest 2012-05-11 10:57:16 yes /var/run/dovecot default 2012-05-11 10:54:09 no my doveconf -n for the mailtest instance: # 2.1.6: mailtest/dovecot.conf doveconf: Warning: service auth { client_limit=4096 } is lower than required under max. load (12288) doveconf: Warning: service anvil { client_limit=4096 } is lower than required under max. load (12291) # OS: Linux 2.6.32-220.13.1.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.2 (Santiago) nfs auth_cache_negative_ttl = 0 auth_cache_size = 16 M auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/mailtest/mail.combined.keytab auth_master_user_separator = * auth_mechanisms = plain login gssapi auth_username_format = %Ln base_dir = /var/run/dovecot/mailtest/ default_client_limit = 4096 default_process_limit = 4096 deliver_log_format = msgid="%m" subject="%s" from="%f" size=%p result="%$" first_valid_uid = 0 hostname = mailtest.geneseo.edu instance_name = mailtest lda_mailbox_autocreate = yes lda_mailbox_autosubscribe = yes login_log_format_elements = user=%u method=%m rip=%r lip=%l lport=%a mpid=%e encryption=%c mail_fsync = always mail_location = maildir:/Mail/mailhome/%Ln/mailtest/Maildir:CONTROL=/Mail/mailhome/%Ln/mailtest/.dovecot-control:INDEX=/Mail/mailhome/%Ln/mailtest/.dovecot-index mail_log_prefix = "service=%s user=%u rip=%r " mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = zlib quota mail_log notify fts fts_squat stats maildir_very_dirty_syncs = yes 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 mbox_write_locks = fcntl mmap_disable = yes namespace default { inbox = yes location = mailbox Drafts { auto = subscribe special_use = \Drafts } mailbox Junk { auto = no special_use = \Junk } mailbox Sent { auto = subscribe special_use = \Sent } mailbox Trash { auto = subscribe special_use = \Trash } prefix = separator = . subscriptions = yes type = private } namespace legacy { alias_for = hidden = yes inbox = no list = no location = mailbox INBOX.Drafts { auto = no special_use = \Drafts } mailbox INBOX.Junk { auto = no special_use = \Junk } mailbox INBOX.Sent { auto = no special_use = \Sent } mailbox INBOX.Trash { auto = no special_use = \Trash } prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/passwd.masterusers driver = passwd-file master = yes } passdb { args = cache_key=%u dovecot driver = pam } plugin { fts = squat mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename flag_change append mail_log_fields = uid box msgid size from subject flags mail_log_group_events = yes quota = maildir:User quota quota_exceeded_message = Quota exceeded (mailbox for user is full).

[Dovecot] dsync migration with preserving pop3 uidl
by Tomáš Herceg 11 Jun '12

11 Jun '12

Hi all, I'm trying to migrate messages from icewarp (merak) mailserver to dovecot via dsync, IMAP migration is looking fine, but I'm unable to migrate pop3 uidls from originating server, probably is something wrong with configuration, but I don't know what. The only documentation i found is on the wiki: http://wiki2.dovecot.org/Migration/Dsync where is bad writen mail_plugins = pop3-migration, i corrected it to mail_plugins = pop3_migration, but it still didn't work, here is my configuration: dovecot --version 2.1.5 dovecot -n # 2.1.5: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-220.13.1.el6.centos.plus.x86_64 x86_64 CentOS release 6.2 (Final)

I think the problem is likely the mdbox storage... There have always been some issues with it and the antispam plugin when combined.

I can only suggest, as a test, trying with some other storage format -- I only use Maildir -- to see if the problem is really in the interaction with mdbox. I'm fairly sure that's likely the problem, maybe the plugin doesn't pass something through append that is needed by mdbox, but I've never even attempted to understand mdbox. Maybe Timo can comment.

[Dovecot] Accessing maildir snapshots through dovecot / namespace
by Karl Oulmi 11 Jun '12

11 Jun '12

Hi, I've the following setup : - FreeBSD 9.0 / Dovecot 2.1.7 - Maildir storage over iSCSI (Dell MD3200i) - Virtual users over LDAP to render the storage snapshots available through dovecot (to allow my users to browse their mail history). Here is my conf : namespace { type = private inbox = yes list = yes prefix = INBOX. location = maildir:/home/%u/Maildir:CONTROL=/home/dovecot/control/%u:INDEX=/home/dovecot/indexes/%u } namespace snap { prefix = INBOX.snapshot.h0. hidden = no inbox = no list = yes location = maildir:/da1/%u/Maildir:INDEX=/da1/dovecot/indexes/%u:CONTROL=/da1/dovecot/control/%u type = private } The problem is that I don't see the content of the inbox folder contained in the snapshots whereas subfolders are perfectly viewed ! Inbox cur|new are is /da1/%u/Maildir/ If anyone have a tip, It would be nice... Regards, Karl. -- _______________________________________________________________ Karl OULMI Centre de Ressources Informatiques Institut de Biologie de Lille - CNRS GDS3366 _______________________________________________________________

[Dovecot] dovecot does not find libpam when compiling with customized prefix
by Roland 11 Jun '12

11 Jun '12

Hello everybody, I try to compile dovecot 2.1.7 with a customized --prefix setting and --with-pam . Although I installed libpam into the same --prefix, dovecot does not find it: checking for pam_start in -lpam... no configure: error: Can't build with PAM support: libpam not found The same or a similar problem seems to have appeared 4 years ago: http://www.dovecot.org/list/dovecot/2008-February/028750.html Which libpam file does dovecot expect in which directory? And possibly there is something wrong with the pam_start function? Thanks in advance, Roland

[Dovecot] Dovecot over NFS
by James Devine 11 Jun '12

11 Jun '12

I'm playing with running dovecot over NFS and I am running into some issues. I have followed the guide at http://wiki2.dovecot.org/NFS and my setup includes 1 nfs server and 1 client running postfix/dovecot. In testing I am running postal via the command: postal -t 10 -c 10 localhost users399 The test file has a list of 399 users to deliver to. I've provided a sample of the errors I'm receiving and my configuration below, I am running dovecot 2.0.19. Any idea what I might be doing wrong and what I might do to resolve it? My ultimate goal is to setup multiple clients with director so each user is still handled on a single machine, however with a single machine I still seem to be having issues. Here is a sample of some of the errors I'm seeing: Jun 6 15:55:12 test-gluster-client1 dovecot: lmtp(12072, testuser130): Error: mdbox /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:12 test-gluster-client1 dovecot: lmtp(11999, testuser99): Error: Log synchronization error at seq=2,offset=556 for /mnt/testuser99/mdbox/storage/dovecot.map.index: Append with UID 2, but next_uid = 3 Jun 6 15:55:14 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: mdbox /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:18 test-gluster-client1 dovecot: lmtp(12133, testuser138): Error: Log synchronization error at seq=2,offset=556 for /mnt/testuser138/mdbox/storage/dovecot.map.index: Append with UID 2, but next_uid = 3 Jun 6 15:55:19 test-gluster-client1 dovecot: lmtp(12076, testuser217): Error: mdbox /mnt/testuser217/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:19 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: mdbox /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(11985, testuser166): Error: mdbox /mnt/testuser166/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(12072, testuser130): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019655 -> 1339019656 Jun 6 15:55:23 test-gluster-client1 dovecot: lmtp(11928, testuser130): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser130/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019655 -> 1339019656 Jun 6 15:55:24 test-gluster-client1 dovecot: lmtp(11954, testuser192): Error: mdbox /mnt/testuser192/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:24 test-gluster-client1 dovecot: lmtp(12130, testuser128): Error: mdbox /mnt/testuser128/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12076, testuser217): Error: mdbox /mnt/testuser217/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12211, testuser60): Error: mdbox /mnt/testuser60/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12112, testuser190): Error: mdbox /mnt/testuser190/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(12047, testuser41): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019658 -> 1339019659 Jun 6 15:55:27 test-gluster-client1 dovecot: lmtp(11937, testuser41): Error: Log synchronization error at seq=2,offset=204 for /mnt/testuser41/mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index: uid_validity updated unexpectedly: 1339019658 -> 1339019659 Jun 6 15:55:28 test-gluster-client1 dovecot: lmtp(11985, testuser166): Error: mdbox /mnt/testuser166/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 Jun 6 15:55:30 test-gluster-client1 dovecot: lmtp(12130, testuser128): Error: mdbox /mnt/testuser128/mdbox/mailboxes/INBOX/dbox-Mails: Invalid dbox header size: 0 My dovecot config is: auth_debug = yes auth_debug_passwords = yes auth_username_format = %Ln auth_verbose = yes base_dir = /var/run/dovecot-service/ disable_plaintext_auth = no instance_name = dovecot-service mail_debug = yes mail_fsync = always mail_location = mdbox:~/mdbox mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = quota mdbox_rotate_size = 16 M mmap_disable = yes passdb { driver = pam } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota } protocols = " imap lmtp pop3" service auth { unix_listener auth-userdb { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imap { port = 10143 } } service lmtp { inet_listener lmtp { port = 10024 } } service pop3-login { inet_listener pop3 { port = 10110 } } ssl = no ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd }

[Dovecot] Dovecot antispam plugin bug: got an empty message
by Petr Bravenec 10 Jun '12

10 Jun '12

It is few months ago I requested help with combination dovecot - dovecot- antispam plugin and dspam. Now I got into troubles with a lot of spam delivering to users inbox. Problem described bellow is now better hidden but stil remains: When moving a message from INBOX to Junk, dspam got an empty message. I made a wrapper about dspamc and there is no input on stdio. The dspam was not trained (got an empty message). Looking to source code of dspam and antispam plugin I suspect the dovecot not to sending any content to plugin when moving from inbox to junk.
