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
