personnaly I find AWL a was of time and often leads to SA not spotting 
spam. Others find it works, but alot of people (like me) find it's only 
useful for small end-user populations (less than 10).

I turn of off by disabling the plugin on init.pre.

I'd check you're trusted_networks etc in spam.assassin.prefs.conf is OK, 
  as that seems to be the cause of lots of AWL problems.
