Indeed as can Scam-backscatter, but I'm attempting to not load the backend
mailserver with connections if at all possible, due to the number of emails
that are received on the antispam machines... (I know that they cache the
results of the lookups, but spammers like to send to dictionaries ;-) )

Thanks for the suggestion though :-)
