Besides mailing lists, bounces are very important for large senders, marketing email companies, etc... The usual rule is to stop emailing any email address that generated a hard bounce, but if you block such bounces due to the policy of the sender of the bounce... Well I guess they are going to be annoyed eventually and may not take the appropriate action, fix their bounces, and eventually block or limit the sender of the original message. _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
