Having temp mdbox files, what to do with them?
by Marc Roos 22 Jan '19

Can I delete these because doveadm is only purging from source, when it is confirmed they are correctly at the destination? [@ storage]# ls -ac1rt m.554 m.569 m.564 m.559 m.561 .temp.1548002572.P1969Q0M313023.mail03 .temp.1548002572.P1969Q1M313023.mail03 .temp.1548002572.P1969Q2M313023.mail03 . .temp.1548002572.P1969Q3M313023.mail03

Changing the imaps port #
by Patrick Mahan 22 Jan '19

22 Jan '19

Dovecot 2.3.4, FreeBSD 11.2 Due to comcast buisness ISP intercepting imaps I need to have my clients connect to non-standard port (9999). Previously I had been using stunnel to receive the imaps connection and forward it to the imap port over 127.0.0.1. But I would like to retire stunnel and have my imap clients connect remotely. I have configured the imap-login service - service imap-login { inet_listener imap { address = 127.0.0.1, ::1 port = 143 } inet_listener imaps { port = 9999 } process_min_avail = 3 service_count = 0 vsz_limit = 1 G } But I am not seeing any listeners on port 9999 - root@ns(1001)# netstat -an | grep 9999 Using sockstat on FreeBSD: root@ns(1002)# sockstat | grep dovecot | grep tcp root dovecot 34800 15 tcp4 *:4190 *:* root dovecot 34800 37 tcp4 127.0.0.1:143 *:* root dovecot 34800 38 tcp6 ::1:143 *:* I have mail_debug = yes, but I don't see any failures. What is the best way to debug why I am not seeing this port number? Thanks, Patrick

Thanks Sami, And I should allow access on the remote server via login_access_sockets?

Unexpected accounts showing up in replication status (doveadm replicator status '*')
by Daniel Schütze 21 Jan '19

21 Jan '19

I have a replication set up with two dovecot 2.3.4 servers. Messages appear to be replicating fine between them, however there is an oddity when I run doveadm replicator status '*' and I'm worried work is being carried out needlessly. Both machines have identical configs and have a mysql backend for username/passwords. Both machines point to the same mysql server and same tables. When I run doveadm user '*' On either machine I am presented with the same correct list of users. The users are presented in the form: username and not username@domain. When I run doveadm replicator status '*' On either machine I receive a list of usernames which includes not only username but also username@domain. Both of these "accounts" have fast sync, full sync and success sync entries and these are not the same times between username and username@domain (hence I'm worried unnecessary work is being carried out). My ee dovecot-sql.conf.ext Has these entires re usernames user_query = SELECT home, uid, gid FROM users WHERE username = '%n' password_query = SELECT username AS user, domain, password, home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid FROM users WHERE username = '%u' [Having copied these in I do see the different usage of %u and %n] iterate_query = SELECT username AS user,domain FROM users The users table is as follows +--------------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+-------+ | username | varchar(128) | NO | | NULL | | | domain | varchar(128) | NO | | NULL | | | password | varchar(64) | NO | | NULL | | | home | varchar(255) | NO | | NULL | | | uid | int(11) | NO | | NULL | | | gid | int(11) | NO | | NULL | | | active | char(1) | NO | | Y | | | mail_replica | varchar(255) | NO | | NULL | | +--------------+--------------+------+-----+---------+-------+ I assume that the duplication of username with and without domains isn't as intended, any suggestions where I am going wrong? I did previously have the servers running with the iterate query commented out and when that was the case doveadm user '*' returned the correct number of accounts but in the format username@domain and the replicator status again 'double listed' accounts as described above.

doveadm proxy list repeats header line
by Michael Goth 20 Jan '19

20 Jan '19

Hi all, just a minor thing: Why does `doveadm proxy list` repeat the header line after each entry? Too me, that just makes the output harder to read. So instead of this: root@mail1 ~ # doveadm proxy list username proto src ip dest ip port info(a)domain1.de imap 80.152.196.98 222.133.127.53 993 username service src-ip dest-ip dest-port info(a)domain1.de imap 80.152.196.98 222.133.127.53 993 username service src-ip dest-ip dest-port info(a)domain1.de imap 80.152.196.98 222.133.127.53 993 username service src-ip dest-ip dest-port tj(a)domain1.de imap 83.149.131.71 222.133.127.53 993 username service src-ip dest-ip dest-port tj(a)domain1.de imap 83.149.131.71 222.133.127.53 993 I'd prefer this: root@mail1 ~ # doveadm proxy list username proto src ip dest ip port info(a)domain1.de imap 80.152.196.98 222.133.127.53 993 info(a)domain1.de imap 80.152.196.98 222.133.127.53 993 info(a)domain1.de imap 80.152.196.98 222.133.127.53 993 tj(a)domain1.de imap 83.149.131.71 222.133.127.53 993 tj(a)domain1.de imap 83.149.131.71 222.133.127.53 993 The repeated header lines also happen with other formatters.
