Managesieve not working

Hi,

I am running dovecot 2.3.7.2 on ubuntu, and have a replication setup.

I noticed that managesieve doesn't seem to be working. On my backup MX, doing a telnet to 4190 gets me the proper greetings, but doing the same on my main server just gave me the normal telnet "Escape character is..."

I get the following info on the server:

root@d0ba5bb19b6b:/# doveadm service status managesieve name: managesieve process_count: 0 process_avail: 0 process_limit: 1024 client_limit: 1 throttle_secs: 0 exit_failure_last: 0 exit_failures_in_sec: 0 last_drop_warning: 0 listen_pending: n listening: y doveadm_stop: n

But when attempting to connect, it doesn't work.

Any advice?

Best, Francis
