Hi,

Jan 26 17:24:44 doveadm(user1 at domain.ltd): Fatal: connect(ip_server_target:4711) failed: Connection refused
Jan 26 17:24:44 doveadm(user6 at domain.ltd): Fatal: connect(ip_server_target:4711) failed: Connection refused
The config is the same for both server.
When checking the FW on both server :
ACCEPT tcp -- anywhere anywhere tcp dpt:4711
Is it the FW who is really blocking this port ? Or something else ??
Any ideas ?
Thx for your support.
