Keep. This feature might help curtail a type of DDoS attack for those that do not use DKIM and want to prevent traffic generated by spoofed random keys selectors. Of course the attacker might attempt to use random sub-domains for the email-address, but bogus email-address domains would be easier to prevent. Keys can and will be pointing anywhere without any expectation that key selectors have a direct relationship with an email-address domain. In other words, key are always stored in some random location. Sender policy would not. -Doug _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
