I'll offer this up: Something is an "attack on DKIM" if it involves input that can cause DKIM to report a "pass" when it should report a "fail", or report "d=example.com" when it should've said "d=example.org". Since the general output of DKIM is pass/fail and a domain name plus some other optional signature stuff, I fail to see how double-From type attacks are attacks on DKIM. Rather, I think these things we're discussing are attacks on MUAs (or on ADSP implementations) that fail to do RFC5322 enforcement or fail to understand what DKIM is telling them. _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
