I tried to set up small mail server from my NAS but got some trouble with SMTP hostname
|SMTP Valid Hostname||Reverse DNS is not a valid Hostname|
|SMTP Reverse DNS Mismatch||OK - 220.240.XXX.XXX resolves to oxxxxxx.com.au|
Is anything can be done to appoint a valid Hostname? From my understanding this set up shoud be done on ISP side, innit?
