Set up a separate instance of spamd that will be used just for
scanning your outgoing mail (obviously this will have to be done with
your local system configuration). Run that spamd with the '-L' option to
disable network checks. One effect of doing that is to cause SA to
choose an alternative scoring set that has been weighted for use in
a no-networks-test environment. See the discussion of the 4-part
'score' values in Mail::SpamAssassin::Conf.
