Re: Dovecot version 2.3.17 - mail replication stopped working

29 Oct 2021


      Hi Aki,
Thanks for confirming it's fixed in master, much appreciated.
Approximately when do you expect 2.3.18 to be released as we found the
functionality provided by this option useful in our setup.
Best regards
Daniel

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.

Hi,
We upgraded to Dovecot 2.3.17 today and mail replication has stopped
working as expected, the error in mail.err is:
