     Quite so.  Remember that for a while TheBat! was spoofed as a spam
client.  For about 2 years anyone blocking just on X-Mailer would have nailed
me and about 3 dozen other people I conversed with on a regular basis.
X-Mailer is a  program generated line and is inheriently untrustworthy.
Blocking on untrustworthy data is a bad idea.  Scoring on it is a much better
route.
