Individual whitelists

[Don Newcomer]

I've been running individual whitelists since yesterday afternoon and it's
working great!  Now, there are just domain names or addresses.  In the
original whitelist entries we had the choice of "From", "To", or
"FromorTo".  Does the custom code work only for "From" or is it a
combination of the three?
