freaking MS crap

[Kurth Bemis]

I own a ISP and we're having problems with the "Snowhite Virus" and outlook 
users...its running rampant..from about 3 weeks back we got one or 2 
bounces a week..now we're up to 40 a day....

I have created a controls/badmailfrom and added [EMAIL PROTECTED] however 
mail still goes though....any ideas why this isn't rejecting mail?
I have looked at the logs and it seems that qmail treats it as a regular 
mail without checking...

any ideas?
