CF RULES

[Howard]

I've got the following running fine and was wondering if anyone had any
comments if I should be running more or less:

-rw-r--r--    1 root     root         6051 Jan 15 13:34 backhair.cf
-rw-r--r--    1 root     root        68703 Jan 17 22:56 bigevil.cf
-rw-r--r--    1 root     root        22814 Jan 17 09:18 chickenpox.cf
-rw-r--r--    1 root     root          302 Jan 16 17:37 local.cf
-rw-r--r--    1 root     root         5589 Jan 15 13:36 popcorn.cf
-rw-r--r--    1 root     root        13914 Jan 18 22:03 uri.cf

Also, does anyone have any comments on running:

Lastly, I get a bunch of these text body mails:

What filter would take care of this?

Thanks
