I'm curious Chris,
Have you had many of the online site email addresses leaked?
Someone trawled the idg.co.nz sites and discovered lotsa live addresses... so now I get mortgage offers for the US galore. Sigh. Sigh. Sigh.
If you were going implement a firewall you'd construct access lists based on the principle "that which is not explicitly permitted, is denied". You'd also allow return traffic from connections you'd initiated. Much of the antispam activity is based around the premise "that which is not explicitly denied, is permitted". You simply can't secure things using this approach. I suspect that for many, many people they could construct a list which said who they were prepared to receive email from. You could add the addresses of people you email to the list (perhaps with a timeout). You then autorespond to anyone you don't recognise with a "Sorry, you don't seem to be one of the people, I communicate with. If you still want to send me email, go to this web site, fill in the form and I'll let you know. Have a nice day". How badly do you want email from strangers? Haven't you got a life?
