Hi, Whenever I try to send something to emails in @att.net I get a reply: host ff-ip4-mx-vip1.prodigy.net[144.160.159.21] said:553 5.3.0 flph831 DNSBL:RBL 521< MY.IP4.ADD.RES >_is_blocked.For assistance
forward this error to abuse_rbl () abuse-att net (in reply to MAIL FROM command) Of course emails to abuse_rbl go unanswered.My IP turns clean on https://www.dnsbl.info/ (all green and one blue timeout).
Anyone had such issues? Any working contacts to AT&T email? Any help appreciated. -- Grzegorz Janoszka
