re: Cryptic spam
That's great for personal e-mail, but you can't do that with one that you rely on for work. A spam filter these days is as necessary as a firewall and AV IMO.
My home ISP gives me up 5 mailboxes I can control. That is the best idea any ISP has had. Now I can just change my e-mail address or set up dummy addresses whenever I want.
