Jeff, If I try to telnet to your e-mail server on port 25 this is what happens,
$ telnet 203.51.63.160 25 Trying 203.51.63.160... telnet: connect to address 203.51.63.160: Connection refused Until this is fixed there is zero possibility to receive inbound mail. I cannot tell if your server is rejecting the connection or if it is the firewall that is doing it. How is your firewall configured? Is it allowing tcp through on port 25 to that address. Does your mail server have a real world ip address or is it being Nat'd by the firewall? In this case what is the firewall? An appliance like a Cisco or are you using Linux/iptables? When you say that you can telnet to the server and it responds how are you testing this? I certainly can't telnet to it on ports 110 25 or 23. But you are visible to me via ping. PING 203.51.63.160 from 192.168.1.10 : 56(84) bytes of data. 64 bytes from 203.51.63.160: icmp_seq=0 ttl=112 time=70.914 msec 64 bytes from 203.51.63.160: icmp_seq=1 ttl=112 time=58.177 msec Are bigpond firewalling further upstream that you aren't aware of? Your log reverse dns's you as CPE-203-51-63-160.nsw.bigpond.net.au So I assume you have some sort of connection / service with them, what is it and are you "allowed" in Telstra speak to have a server? Once you have fixed the access to port 25 from outside then you should start receiving e-mail.
