I will happily be set straight on this. Reference please? I am going by https://certified-senders.org/wp-content/uploads/2017/07/CSA_Admission_Criteria.pdf Designating IP Addresses 2.1 In principle, all IP addresses used by the CSA Sender are listed on the whitelist. Using mail servers that are not to be whitelisted is only permitted in the following case: [list omitted, interested parties may view the document directly.] Let me just tell you cases that meet "the following case" are a minuscule minority in the non-CSA-whitelisted, CSA-member-sent email that our spamtraps get. We get a LOT less email than you do, obviously, so YMMV. -- 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
