On OpenSuse 15.2, the assigned IP address has only SSH port open.
The localhost has several more open, which allows me to run mail
server, by referencing localhost.
However, this causes other machines on local network to be denied
access to the email server.
Firewall is not enabled, iptables shows no rules.
I am puzzled.
Are you running postfix as your mail server? If so, what does "postconf
inet_interfaces" say? If it says "localhost", you need to edit it to
say "all" and restart.
Sorry, that was too telegraphic; you need to add
inet_interfaces = all
to /etc/postfix/main.cf and restart.
