Ed, >header UNDISC_RECIP To =~ /^Undisclosed-Recipient*:\s*;$/
I think your regexpr miss to catch the < and > that surround the "Undiclosed...". It matchs a line starting with "Undisclosed" and continuing with "recipient" (none to many t at the end) followed by none to many spaces, ending by ; > I was surprised to see such a low score on this one... I bet many valid maling list use the undisclosed recipient thing, so it is not a strong indicator of spam.
