Hii,
My company's email is being blocked by ATT. I get the following error message when I email from to an @bellsouth.net client.
Failed recipient:
xxxxx@bellsouth.net Reason: Remote host said: 553 5.3.0 alph128 DNSBL:RBL 521<199.193.117.57> is blocked. For assistance forward this email to
abuse_rbl@abuse-att.net I've checked to make sure our IP/domain is not on any spam lists. It is not. Can you remove my IP from ATT's blocked list?
Thank you.
