First thing first, this isn't necessary a Dovecot related thread and using a challenge-response system like the one suggested by the initiator ("click here if you're not yet another bloody SEO guru") is plain wrong for several reasons, having said that: On 12-06-2020 11:56, Andreas Born wrote:

Wrong mailing list. You need to ask on the list for the MTA you are using (Sendmail, Postfix, &c). Actually, this sounds like a job for a custom milter, which would look at the domain name of the sending system, and reject the mail with your message. Dunno if there is one that works exactly
