Delist/Unblock IP Address
Dear AT&T Postmaster,
we are trying to send emails to users with ids using "naturalhealthway.com" and "dakinekratom.com".
I need to unblock an IP 22.214.171.124 ; 126.96.36.199 and 188.8.131.52 of my mail server that sends legitimate notifications to clients and tried to proper unsubscribe. But I cannot access the blacklist removal request URL http://rbl.att.net/block_inquiry.html as it is not opening at all.
The IP address used for email communication are 184.108.40.206 ; 220.127.116.11 and 18.104.22.168
