*grin* Yes, I saw that, which is what put me down the path. Once I
realised that exchange could be persuaded to give sensible data
(including headers and such) I wanted to implement an auto-learning

inline anti-phishing and/or trailing signature might pollute the Bayes
database - or am I worrying unecessarily?
