If I may revise and extend my remarks, an MSA, unlike an MTA, can 
reasonably fix a lot of flaws that an MTA would have to either tolerate or 
reject, since it typically has metadata like a sender (whoever AUTHed) and 
a date (now).  And as others have noted, the costs of rejection are 
typically a lot less, just bumping the message back to the author to fix.
