Don't use 'catch-all' email addresses
If you have your own domain name - they are typically configured to allow 'anyone'@your-domain-name.com
This is convenient 'initially' you may not know which email addresses you want and it also has the benefit of catching mis-spelt email addresses.
But spammers love it - they can send to anything-they-like@your-domain-name.com and you will receive it!
So we would recommend you do it the other way around - instead of receiving everything - specify just the email addresses you want to receive and reject everything else.

I use a catch-all email address as part of my spam defense. I pull the mail from the catch-all account using fetchmail and then use procmail (on my own linux server at home) to distribute the email to the six people in my family based on the first letter of the username. That allows each of us to create separate email addresses for each person or company we deal with, and if one starts getting spam, I filter on the "to" field in procmail. Works great! I get almost no spam that I actually see.
