So what should be listening on port 262? Unix sockets are not tcp ports.

I am trying to relay with [ msmtp ] via [ lmtps ] from a lan host other than [ dovecot ] is running on. [ dovecot config ] > service lmtp { > unix_listener lmtp { > #mode = 0666 > } [ ss -wxl | grep lmtp ] > u_strLISTEN 0 100 /var/run/dovecot/lmtp 68262 * 0 So far so good. Now from the other lan host -> [ msmtp --serverinfo --tls --tls-certcheck=off --host=172.24.109.6 --protocol=lmtp --port=262 ] produces: > msmtp: cannot connect to 172.24.109.6, port 262: Connection refused
