Rene, While I value the benefits of "owning" where my mail resides; I have recently given up my dedicated co-lo server (which in retrospect was silly.. it was so cheap!) and moved all of my mail to Google for Domains.
I have had healthy conversations regarding the pro's and con's of hosting your email with them, but at the end of the day; I get very little spam (Thanks Postini!), and it "works in the places I do". While perhaps not the short term answer to "how do I stop spam", it might be interesting to see how something like Google for Domains might work, or not work for your situation or company.
