Actually, my reading of the code was incorrect, sorry.  The current
version just looked for forged hotmail received headers if From has
hotmail.com in it.  So the name does make more sense.

I got confused because in 2.50 there are now 2 rules.  One looks for
Received has forged hotmail.com (FORGED_HOTMAIL_RCVD, similar to the 2.43
one but doesn't look at From), as well as a new one which checks for From
has hotmail.com but nothing saying hotmail.com in the Received headers
(SEMIFORGED_HOTMAIL_RCVD, only triggers if FORGED_HOTMAIL_RCVD doesn't).

The results, so far, are:

That third column is % of spam messages matched, fourth is % of ham
messages matches, and fifth is "% how spammy" the results are.

So the results basically say that the new FORGED_HOTMAIL_RCVD works very
well, but SEMIFORGED_HOTMAIL_RCVD isn't so hot but still more of a spamsign.

I was right about why FORGED_HOTMAIL_RCVD is triggering for you in 2.43
though: From has hotmail.com but there are no valid hotmail Received
headers.  As you can see, apparently someone had the same problem and
split the rule into 2.
