Hum... If we decide not to consider incompetence or error, then it
might be a way to prevent accidental CGI form mail exploit.

Add to your whitelist and it will be fixed. Adding all local
IPs (including loopback) to the whitelist is a good move anyway: it
won't decrease the system's security except if you have very special
setup and it will improve on performances since local relays won't
yield a DNS lookup.

Good luck,
