The whitelist can be added to the access file.  It doesn't do a pause on
outbound mail however - it does it when a remote mail server attempts to
send to us.  Basically says "cbj mail server, can I put you on hold" and
then makes the remote end spin it's wheels for 10 seconds.  Real mail
servers are built to handle that sort of thing, as a rule.  Spambots just
want to shotgun out as many messages in as little time as possible so blow
right past your domain.

At least that's my understanding...
