Interesting. When the other side will be machine, which is expected to "talk" with me, i will consider to complain. IMO you are wrong about "not on any OSI layer" as SMTP is L7, and rejecting connection is against RFC5321 (without good -- i understand attack/abuse -- reason, see sect 7.9). IMO the rest depends on point of view, my is that because whole rejection is IP based, it is L3 thing, and doesn't matter that it happens in L7. Other point of view can be, that it is L7 thing, as all previous layers was success. Sameone other can consider the connection as SMTP stage, before client sends EHLO, etc... But that doesn't matter, as it is wrong at all. ... But yes, you changed my mind about t-online.de blocking. You are right, that i drop to their (bad) level by that. regards -- Slavko https://www.slavino.sk/ _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
