Yes and copying parts of relevant code of an MTA could be one.

Well, the whole world can pass whatever it wants to an MTA, it's
supposed to be listening on internet facing port 25 all the time, that's
it's mean reason of existence. An MTA is particularly well suited to
take any kind of abuse, because that's exactly what it's expecting.
Unless in cases such as Owen mentioned I'd say it's a pretty good
solution. The madness to me lies in making your own email validating code...
