As Mike specified earlier in this thread it is not spamassassin who will 
drop spam but the milter software based on the score given by 
spamassassin. You should check it's configuration for such options. I 
use qmail with qmail-scanner, and spamassassin and qmail-scanner drops a 
lot of spams every day. Every week or so I get *1* spam that has a score 
low enough to escape this setup and gets in my mail. If the milter 
software you installed doesn't have the option you should try something 
else but I doubt it is the case.
Anyway, I haven't heard if you tried to set up SPF. Don't know how easy 
is to have it working with sendmail (on qmail I just have to apply a 
patch before compiling it) but I think it's a great tool that isn't 
spread as much as it should be and should address your problem at the 
"root of the evil :)".
