The tricky question is: How are you sure it's unwanted? Suppose the body of the email contains a well-known text of a Nigerian prince scam. Surely that email would be unwanted, right? Except... What if the email was beng sent to an abuse team to complain that *they* sent such email? What if this is someone asking a trusted one whether the deal is real? ...or their reply that it is not? What if it's a blog / mailing list post when someone sent that? Or a mail forwarded from a spamtrap? Or a newsletter alerting from certain scams on the rise? Not to mention a mailing list such as this one, discussing spam topics. > In any case, some one know what are the IP address in the "high-risk > delivery pool" of Microsft 365? This is a good question. Microsoft throughly documents its use of an High Risk Delivery Pool... but not which ranges it uses for that. According to https://o365info.com/high-risk-delivery-pool-and-exchange-online-part-9-17/ it would be using 157.56.0.0/15 Regards _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
