if you really report 500 mails each day you should give over your job to someone with more qualifications because we are hosting some thousand mail-addresses and i could never report 500 spam-mails per day because they are not received without blocking major providers http://www.barracudanetworks.com/ a) intention-filtering, hourly updated rules b) blacklist c) block by PTR to get rid of 99% of all spambots your primary job as admin is to make sure that legal mails are received and not to play around the whole day to maximize false-positives, long after that comes the fight against spam 10 spam mails are less damage than a single false-positive
