Apart from the URIBL check, the DCC, Razor2, Pyzor and IXHASH checks require
you to queue the mail before they can be run. I am not sure how would one
delegate the responsibility to the MTA? And even if one can, the time
involved in scanning will be considerable opening a DoS attack vector.
Since I am aware of your contributions, I am inclined to the fact that I
might have gotten it all wrong. Please correct me if that's the case.
