Outbound SMTP (port 25) Does AT&T West block outbound port 25?
can anyone test the following 2 IP's?
126.96.36.199 Port 25
188.8.131.52 Port 25
I appreciate your help we are trying to resolve a support issue for some customers that is causing a lot of issues and we need to find out specifically what if any SMTP servers are blocked.
AT&t has blocked outbound 25 for years.
