I have learned to keep a personal e-mail address for friends & somewhat trusted people, but never businesses. Businesses (and all government offices, kids' school,...) get their one-time address. If spammers somehow get to it, it is much easier to cut them off, and I also know who leaked the address to them.
Of course, http://www.mailcatch.com/ rules for those one-time "no, I will not let you spam me" registrations.
