Does AT&T Southwest filter outbound port 25?
I'm wondering if AT&T southwest filters outbound port 25?
Specifically I am wondering if you can reach the following 2 IP's on port 25
220.127.116.11 Port 25
18.104.22.168 Port 25
I appreciate anyone who can answer this as I am getting conflicting reports.

Yes, ATT SW does block port 25 (SMTP) to stop infected machines from sending out thousands of e-mail. A simple call to customer service to get it unblocked will fix this.
