spammasons
A brotherhood much like freemasons that assist in the sending of spam to a lesser or greater extent. Often these appear outwardly to be respected members of the (anti-spam) community. Commonly those that operate (stealth) whitelists, certification services or offer a mechanism/facility to 'grease the wheels' of spam through an email system.
Their messages always get past blocklists - they must be part of the spammasons.

It was odd that the spam email was not blocked as it was so obviously spam - perhaps the sender is a spammason?
