Thanks for the help and the advice, but this directive a) was already
enabled, and b) doesn't stop sendmail from sending email out, which is
what I want.  Basically, this is what I'm hoping for:

ACCEPT: local mail only
SEND:	local mail only

Also, is there a simple way to have sshd drop requests from selected
IPs?  This box has been up two days and it is already on some script
kiddie's hit list.  Thanks.
