Are you trying to deliver the mails using 465 port ? Thats now obsolete and postfix no more support mail delivery using that port.
Regarding :-
[root@mail ~]# telnet mail.domain.tld 10025
Trying 10.10.10.119...
telnet: connect to address 10.10.10.119: Connection refused
This is expected behavior. Can you try telnet to 127.0.0.1 on 10025 ?
telnet 127.0.0.1 10025 |
