Extra Sare Rules for meds?

[Jim Maul]

I realize this isnt exactly a SA question but i figured theres enough 
people on this list using sare rules to give some feedback.  I work in a 
hospital where we obviously receive a lot of legit emails with drug 
names in them.  However, we also receive a lot of spam with drug names 
in them as well.  I know there are sare rules to catch these sort of 
things but the question i guess is can these rules distinguish between 
the two?  The difference it seems is that in the legit emails they dont 
try to hide the drug names and in the spam they do.  Before i install 
some of these rules, i wanted to hear if anyone has had any experience 
with this type of situation.

Thanks
Jim
