Dovecot version 2.3.17 - mail replication stopped working

[Daniel Botting]

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
