ok, everybody, let's add this to the top of your helo_hostnames.regexp
/\[[0-9]{2,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\]/ DUNNO
HOWEVER, if the spammers put _your_ IMGate's IP in [] as THEIR helo field,
then that's a reject.
eg, for my mgw1.meiway.com, that would be:
/(\[212\.73\.210\.75\])/ REJECT IP must not contain an IP address, HELO = $1
