Look at them and see if they'd be plausibly be used for mail. Those Amazon subtress are names they use for random hosts in the AWS cloud. I don't think Amazon lets you send direct port 25 mail without making other arrangements, and even if anyone did, I don't care because it makes no business sense for anyone to use those subdomains for mail. If you do want to send mail from AWS cloud hosts, there are plenty of ways to do it, but they don't involve sending mail with domain names like bob.s3.dualstack.eu-central-1.amazonaws.com R's, John _______________________________________________ dmarc mailing list [email protected] https://www.ietf.org/mailman/listinfo/dmarc
