Actually, I would like to use it as outbound load. Ah... I see what you are saying (smtpd).
I guess the master.cf changes are irrelevant. In any case, to test I issue telnet 192.168.0.249 25 from a workstation on this lan. I am expecting to connect to postfix on 192.168.0.244. If issue telnet 192.168.0.244 25 or telnet 192.168.0.245 25 from a workstation on lan or from 192.168.0.249, it works. Any help is appreciated.
