Perhaps it could be taught, though. I guess you could add some
Perl code to the mimedefang-filter script to
- check the domain part of destination addresses whether it is
  delivered locally (eg. by looking it up in local-host-names)
- if so, look up the local part in aliases and/or virtusertable
  to find if it is delivered to a local shell user
- if found, look in that user's home directory for a
  .spamassassin/userprefs file
- if it exists, use it.
