I like Yahoo's approach-- they do their disposable email aliases like this:
Where basename is user-chosen (and not necessarily related to the real email address), and the suffix has to be registered ahead of time (so a spammer can't just start randomly generating suffixes to avoid filters).
Fastmail has subdomain addressing. eg. [email protected] which is a lot harder to detect.
