No, i have not tested under SA 3.0.1, I'm still currently on 2.64 but will
probably upgrade to the 3.x family once 3.0.2 is out.

However, I can tell you you're going to have to manually disable the AWL in
your or spam.assassin.prefs.conf if you don't want to use it with
SA 3.x. The MailScanner.conf option doesn't seem to work for 3.0 yet, and
Julian is aware of it and working on it.
