Dovecot version 2.3.17 - mail replication stopped working
Hi,
We upgraded to Dovecot 2.3.17 today and mail replication has stopped
working as expected, the error in mail.err is:
Oct 28 10:27:44 hostname dovecot: imap-login: Error:
net_connect_unix(/var/run/dovecot/stats-writer) failed: No such file or
directory
Oct 28 10:28:47 hostname dovecot: doveadm: Error: sync: invalid option
-- 'T'
This is constantly repeated afterwards
All the files in /var/run/dovecot have last modified time of 10:27
The permissions on both hosts for this file are:

Appears option T got removed by accident. We'll fix it latest for 2.3.18, and we'll let you know once it's fixed in master. You can either rollback to 2.3.16 or remove -T from sync options in config.
