At the risk of tempting fate, the degree to which I suffered from spam changed radically - and for the better - after I changed to broadband via an ADSL router. My isp also changed (from UKGateway to Tiscali, who took them over) which may have had something to do with it. I get about 10-15 spams a day now, which at broadband speed is simply not a problem - I tried the various filters but the size of the problem did not warrant the extra complexity. I use my 'real' address, and don't take any particular precautions apart (obviously) from instantly deleting, unopened, any email I don't recognise the sender of. Not a feasible strategy for a business user, I freely admit.
