In the case of an MUA, an invalid address will result in a notification

only if it's an envelope recipient address.

when gateways have to translate addresses from one format to another (as they do between X.400 and internet mail), they should make sure that the
resulting addresses are valid syntax.  this is just sanity checking.
the reason it's necessary is that there are usually some addresses that cannot be translated. but that's not the same thing as ensuring that the
address is valid.

As noted above, the most important thing is that the sender envelope
address be usable.

in a news-to-mail gateway? I think not. the sender of a usenet message doesn't want to know whether some random recipient got the message.

rather than trying to fix internet mail to
accommodate a bad idea in Usenet, maybe the Usenet people need to come
up with a better idea.

Usenet news is an application of the RFC [2]822 Internet Message Format.

no more than SMTP is an application of the FTP protocol.  in either case
the two are similar but different protocols, with different syntax and
semantics.  there are both advantages and disadvantages to having
usenet and [2]822 so similar.
