My guess would be that quite often by the time mail reaches a point
where the internet rules apply it can be impossible (or impractical,
I guess its always to send mail back to the From: address, and await
a reply indicating that the address works...) to determine whether an
address is valid or not.   Mandating the impossible doesn't seem useful.

And even where a mailer can determine that the address is invalid,
it can happen that the same address is in the envelope (in fact, happens
all too offten).  In these cases, the destination address is quite
often reasonable, so its possible to deliver the mail, but not possible
to rreturn it.  Even if the recipient can't just "reply", he may know
a working return address, it would seem better to deliver the mail than
just drop it on the floor, mandating validation of the From: would
make this illegal.
