To me, such functionality (using different SA rules for each domain) is very desirable, specially on mail hubs..  What about spam_assassin_init?
-----
spam_assassin_init([ $config_file ])
              This function returns the new global Mail::SpamAssassin object with the specified or default  config  (outlined  above).   If  the  global  object is already defined, returns it -- does not change config files!  The object can be used to perform other SpamAssassin related functions.

Could one delete the global Mail::SpamAssassin object and then create a new Mail::SpamAssassin global object with this function call?  Is this possible? Is it recommended? Are there internal MD architecture issues?
