That's part of what I meant by "bona fide MTA". Lots of spammers
don't come back for a retry either - and I see *that* as an
advantage...

But sure, I presented a technical option, which you can use or not as
you choose. I can't - and have no wish to - try to tell you what your
policy should be, I can only say that, so far (and we've had this in
effect for quite some time now), it has worked for us, and the users
have not reported any problems which could be traced back to this
procedure.

I'd say that such an MTA isn't participating properly in email, and
the consequences are their own responsibility.

Multi recipient mails offered from such providers, in my experience:
if they're not spam, they're typically routine mailing lists which the
users have signed up for. Anyway, prompt delivery isn't by any means
guaranteed by SMTP! A few hours seems to me to be no big deal for
that kind of material. I can think of plenty of other reasons for
mail getting deferred (e.g a temporary DNS SERVFAIL) for longer.
