Subject: Signature to trap Mimail.C

This should trap the Mimail.C variant of the Mimail worm.  We do not currently
use Mail Sanitizer, however it has helped me set up some of our schools mail
filtering.  I tried to modify it for use in your sample Local Rules script file.
 Hopefully this will help others.  If you have any questions or comments feel
free to contact me.
