Be aware that quite a number of mailers will treat 5xx at this stage
as retryable. You're better advised, in general, to wait to RCPT-TO
time - and then hit them on the head for their earlier transgressions.

Some idiot mailers will then tell the sender that the recipient does
not exist, instead of telling them the real reason that you sent: but
that's hardly your fault.
