As I keep saying, we would not have a business at all if any ESPs actually removed bounces. So thank you to everyone who doesn't. If there are entities that do, I don't know which ones they are. :-D Way back when, some people who are also on this list kept complaining that simply keeping domains registered without an A and MX (causing NXDOMAIN for mail delivery) is not a proper bounce, because you (as the sending entity) are somehow not able to trust the results your own servers produce, but have to get third party validation for the fact that an address doesn't exist (which I think is totally bass-ackwards), but anyway, we started 550 5.1.1'ing addresses during the timeout period of new domains we acquire, and still, no change. There is also the issue that anything that Operator X finds out while processing data for Customer X1 cannot apply to Customer X2 because anything to the contrary makes Operator X a DATA CONTROLLER in their own right from the perspective of the GDPR and what did I say about that just a few messages ago? -- Atro Tossavainen, Founder, Partner Koli-Lõks OÜ (reg. no. 12815457, VAT ID EE101811635) Tallinn, Estonia tel. +372-5883-4269, http://www.koliloks.eu/ _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
