Hello all, I am attempting to send mail from a M365 tenancy, however, we are seeing issues with it being filtered due to the address appearing on bl.spamcop.net. "Decision Engine classified the mail item was rejected because of IP Block (from outbound normal IP pools) -> 550 mail from 40.107.107.97 refused, see http://www.spamcop.net - Your mail provider is blocked because is sending SPAM." If there is anyone on-list from Microsoft, could you please take a look? It's causing issues 🙁
Thanks, Christopher Hawker
