Delist/Unblock IP Address
Dear AT&T Postmaster,
Our company tries to send emails to users with ids using sbcglobal.net, att.net. However, we have observed that the same are not being delivered.
IP address used for email communication is 18.104.22.168.
Could you please help me to check whether my IP is Whitelisted and assist me further in solving the issue ? I have repeated tried to email email@example.com but have never received any response from them.
Please advise and help.
