I use SpamAssassin (www.spamassassin.apache.org) and outlook filters that I update often. Between the two filters 80% of spam go to a "spam folder" that I look quickly once a day and delete.

I agree, that getting rid of the catch all would cut down on spam but sometimes clients/customers type the wrong email and it's nice to be able to catch those.

One last thing you can do is to block all of Korea and China. There are some good lists that you can put into your firewall and block ONLY email if you wish and leave the webtraffic. Of coruse, the servers we maintain we ask suggest to the clinet we also block web traffic from those networks. When was the last time anyone got real orders or emails from China??? Really???

The only other way to get 99% reduction in spam is to use a 3rd party mail service that asks the sender to validate their email address before it sends it to your system.
