Sure.

As it should be.

No -- the error you quote above isn't a temporary DNS error (i.e. "the
resolver failed to answer my question"), it's a "that domain does not exist"
successful response.  That means the host does not exist, and there's no point
re-trying later.

qmail will bounce the message, and the author/sender will be notified.
