I have the RBLs setup... mail to unknown users is being rejected...I will
look through my setup to see if non-FQDN HELO is being rejected. 

Thank you for the input

Before you start looking too closely at spamassassin rules, have you set up
some basic anti-spam settings on the MTA side? In particular, rejecting
invalid and non-FDQN HELO can be a big help, as can one or two reliable RBLs
(spamhaus zen is generally considered safe enough to reject outright at MTA
level, for example). And of course make sure you're rejecting mail to
unknown users rather than diverting to catchall accounts.
