Connection between postfix and dovecot failing

[Sytse Kuijk]

Well, I tried that. I can connect a telnet session on that port and that does not refuse the connection, it sits there waiting, but I do not know the protocol so I cannot check if it does what it is supposed to.

I also checked who is listening on that port, here is the dialog:

sh-3.2# sudo lsof -i -n -P | grep 10024
perl5.18  75844       _amavisd    5u  IPv4 0x866f6119e39f833d      0t0    TCP 127.0.0.1:10024 (LISTEN)
perl5.18  75844       _amavisd    6u  IPv6 0x866f6119e03f253d      0t0    TCP [::1]:10024 (LISTEN)

looks sort of correct to me…
