You need to protect this with a whitelist, or you wind up blocking mail from
places like hotmail an yahoo (and, rarely, Gmail).  Those places do have
legitimate customers in addition to bad actors.

[As it happens, I was just working on a whitelist entry that was needed
because of a manual blacklist...but before that there were several honeypot
