Hi,
this is cool, you asked and answered yourself.

I'm delighted about somebody else using RegExes with the Spam-Word Filter.
For me, the line you've created seems to be perfect. My only objection would be, that it's a relatively unspecific entry. But I understand that this may be a help, if it belongs to a recurrently reappearing spam mail.
Perhaps you want to help me test my new spam-words list? If you want then download my updated list, unpack it, copy it into the folder "C:\Programs\Spamihilator", end and restart Spamihilator, and send me a feedback about how it works with you.
It could be set too critical for english users, but I would be glad someone in an anglophone country to try it. But it could be better to save your old "spampoints.ini", e.g. as "spampoint.ini_old".
Regards, Chactory
