This is something the lists BCP could discuss. Perhaps something like: bounces with enhanced status codes of 5.7.1 should not be counted against the recipient as they are done for message-specific policy reasons and not for something more general. (I might have the "5.7.1" wrong, but you get the idea.) _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
