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.
15.2 support has ended. Why not upgrade to 15.3 and see if that fixes it?
Because the reason is not the operating system but the postfix config. Upadting will exchange nothing here.
# postconf inet_interfaces inet_interfaces = all
if there is another output, do
postconf -e "inet_interfaces = all" postfix reload (or postfix restart)
to have postfix listen to all interfaces and not only to localhost.

Thanks to all. It worked. Guess I forgot some basics. Next is to create some certificates specific to use with postfix, but that is another story. joe a.
