a message of 78 lines which said:
If the test failure occurs at SMTP time _and_ an explanation text
has been provided, send a separate bounce message containing that
explanation, as well as the SMTP 55x rejection.
If the test fails, it means the address is probably wrong (mail sent
by a worm, for instance), so sending a bounce to an innocent guy does
not seem a good idea.
