theres no substitute for reading the docs! SA is a complex piece of 
software and you need to understand at least how it works. but...

- make sure it is getting plenty of ham training and not just high 
scoring spam. You may need to adjust the threshold(s) for this.
- make sure you feed back the false positives and negatives so it learns 
from them.
- remember when feeding messages back in, they need to be as pristine as 
possible. Try to remove any extra markup they may have from MailScanner 
and your mail relays.
