SMTP port been blocked


Hi all


I'm a new Optus cable user and I'm using 3rd party mail service. So I need to access port 25 of 3rd party IP, but it been blocked by default.


Tried to unblock it but the web page no loger work: Where can I disable this function?

Blocked or rejected.. Normally you'd get an error code and the explanation simular to "No Relay Alllowed". Are you receiving any codes?

Cheers Dave

No code, I believe it is blocked. I captured the packet, wireshark shows TCP request to our smtp server port 25 had no response. The server works fine with mobile network or others ISP.
