Non-Existent Log File

My /var/log/maillog was getting pretty big because of lots of testing and re-configuring I've been doing lately with both Dovecot and Postfix. I figured just remove /var/log/maillog and it would be re-created. It wasn't--not by Dovecot, not by Postfix. I had to manually create a new one, put one character in it, save it, properly secure it with chmod, and then Dovecot (and postfix) messages got written to it. This can't possibly be the proper procedure to clear maillog messages ... can it?

Error when starting Dovecot
by Steve Matzura 13 Jun '15

13 Jun '15

After applying some changes to 10-master.conf as detailed at http://wiki2.dovecot.org/HowTo/PostfixDovecotLMTP I receive the following when trying to start: doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-master.conf line 49: Expecting '{' I'm trying to enable LMTP. The instructions say: Socket configuration The actual socket is configured in /etc/dovecot/conf.d/10-master.conf. The LMTP service can be bound to both INET or Unix sockets. In this example a Unix socket is placed inside the Postfix spool with appropriate permissions set: service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } I copied this block and placed it in my copy of 10-master.conf. Line 49 is the first line of this block, and there's clearly a left-brace there. The braces match, too. Thoughts?

Imap Notify
by Tony Morehen 12 Jun '15

12 Jun '15

I'm trying to enable Imap Notify in Dovecot 2.2.13. I know that's a bit out of date, but that's what's provided with openSuSe 13.2. The first thing I did was add mailbox_list_index=yes to /etc/dovecot/dovecot.conf. Both doveadm -n and dovecot -n show the change. I then used doveadm reload to force dovecot to reread its config file. Despite this, NOTIFY did not show up it Dovecot's capabilities: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. I then did a systemctl restart dovecot.service and still no luck: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. I also have noticed that the Maildirs of my various accounts include a dovecot.list.index file with a current timestamp, but no dovecot.list.index. So, where do I go for here? The output of doveadm -n: # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.16.7-21-desktop x86_64 openSUSE 13.2 (x86_64) disable_plaintext_auth = no log_path = /var/log/dovecot/dovecot.log mail_location = maildir:~/Maildir mail_max_userip_connections = 50 mailbox_list_index = 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 passdb { args = /etc/dovecot/passwd.dovecot driver = passwd-file } postmaster_address = Tony@localhost protocols = imap lmtp service auth { unix_listener auth-master { group = mailgrp mode = 0660 user = mailuser } } service lmtp { executable = lmtp -L inet_listener lmtp { address = 127.0.0.1 port = 2525 } user = mailuser } ssl = no userdb { args = /etc/dovecot/passwd.dovecot driver = passwd-file } protocol imap { imap_client_workarounds = tb-extra-mailbox-sep } protocol pop3 { mail_plugin_dir = /usr/lib/dovecot/modules/pop3 } protocol lda { log_path = /var/log/dovecot/deliver.log mail_plugin_dir = /usr/lib64/dovecot/modules mail_plugins = sieve } protocol lmtp { log_path = /var/log/dovecot/deliver.log mail_plugin_dir = /usr/lib64/dovecot/modules mail_plugins = sieve }

1.0.15 gone, can't start version 2
by Steve Matzura 12 Jun '15

12 Jun '15

On advice/recommendation received on this list, I removed version 1.0.15 with: rm -rf /usr/local/dovecot However, now that I have version 2 properly installed, configured, and ready to start testing with Postfix, it appears the old version is still in /usr/local/sbin, /usr/local/include, /usr/local/libexec, /usr/local/lib and /usr/local/shared/doc. Thinking that anything in /usr/local is something that was installed s a result of having built it from source (which 1.0.15 definitely was), should these also be removed?

That should give you a good idea about what's wrong with your setup. http://lmgtfy.com/?q=dovecot+ssl+setup# B

Replication: "cross-updates" of mail meta-data
by Andre Nathan 11 Jun '15

11 Jun '15

Hello I have a two-server dovecot setup using replication. Each server runs two dovecot instances, one for director and another for the backend. Initially I set up a single server, got it all working, then rsync'd the data and index partitions to the new one and started the clusters (I used rsync as a way to speed-up dovecot's initial replication). Both servers listen on a virtual IP addresses load-balanced by IPVS as well as their own IP addresses. When I started dovecot in the second server, users started reporting that some of their messages were missing. I noticed that while the mail data seemed to be up to date in server1, it wasn't in server2; however, the indexes were being updated in server2 but not in server1. For example, "doveadm quota get -u some-user" would report the wrong value in server1 and the right value in server2, while a "du" would show that only server1 actually had the most up-to-date data. At the moment I had to take down server2, because as soon as dovecot is running in it, users start reporting missing messages again. To solve that problem, a "doveadm force-resync" in server1 isn't enough. I either rsync the index files from server2 or remove the indexes in server1 before the force-resync, which then works. Has anyone ever saw anything similar to this? Any help would be much appreciated. I'm running Ubuntu 14.04 with dovecot 2.2.15 with the configurations below: === Backend instance === # dovecot -n # 2.2.15: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-37-generic x86_64 Ubuntu 14.04.2 LTS auth_master_user_separator = * auth_mechanisms = plain login auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@= auth_worker_max_count = 10 disable_plaintext_auth = no doveadm_password = secret doveadm_port = 12345 listen = server1.mydomain.com mail_fsync = never mail_gid = dovemail mail_plugins = " notify replication quota" mail_uid = dovemail managesieve_sieve_capability = fileinto reject envelope vacation subaddress comparator-i;ascii-numeric relational regex copy include vacation-seconds imapflags notify namespace { inbox = yes location = mailbox SPAM { auto = subscribe } prefix = separator = / type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-master.conf.ext driver = sql master = yes pass = yes } plugin { mail_replica = tcp:192.168.0.2:12345 #

Error starting 1.0.15 with SSL_DISABLE=No
by Steve Matzura 11 Jun '15

11 Jun '15

When starting Dovecot 1.0.15 after building it from source using the standard procedure, I receive the following message when starting, even though SLL_DISABLE=No: Error: SSL support not compiled in but ssl_disable=no Fatal: Invalid configuration in /usr/local/etc/dovecot.conf How is SSL support configured and built in? I know it has something to do with the --SSL_CFLAGS flag.
