Thank you. SPF breakage occurs where a user has configured one of their email addresses to automatically forward their mail to another of their email addresses, and this is (commonly) handled without rewriting the "envelope from". So it fails SPF checking because the forwarding server's IP does not match the "envelope from" domain's SPF record. Also, enough people seem to be offended by the solution to this problem of rewriting the envelope from that it is a significant barrier to adoption. At the moment I do not believe DKIM style solutions cause breakage. Honestly I have not looked into them enough. But as you said: Simplicity. At a brief glance, MTX does not have the problems listed here: http://en.wikipedia.org/wiki/DomainKeys_Identified_Mail#Weaknesses (message replay, arbitrary forwarding, breakage by (mailing list) modification of email, CPU overhead) -- "When we remember we are all mad, the mysteries of life disappear and life stands explained." - Mark Twain http://www.ChaosReigns.com
