That is a broken test.  Unless the mail actually gets delivered to the target
address, the server in question is not actually an "open relay".

Bouncing the mail back later is a perfectly acceptable way of handling a
bogus recipient address.

These self-proclaimed testers who want instant gratification (i.e. errors
during the initial SMTP conversation) are trying to force us to process mail
in a *very* inefficient sendmail-monoblock fashion...
