White List
AT&T Moves Toward Mail-Server Whitelist
Gunfighter writes “In an apparent attempt to quelch the amount of incoming spam, AT&T has asked their customers, partners, and business clients to provide them with IP addresses of their mail servers. All other mail will be discarded. To quote the message: “… In order to continue to allow email to AT&T you need to provide the IP addresses of all your outbound email gateways. If you do not respond immediately, your access may not continue.””
