I propose a web-based form _with_ an image rendered email address.

Using the image rendered email address provided. You just cant click on

One might want to make it obvious that the image is an image rather than
text, so that unwary users arent tempted to try cut and paste.

But we do want google et al to index the archives don't we? Ive found
myself joining all sorts of lists that I found googling for this or that

Put the raw mbox behind a reverse turing test. (See
http://www.captcha.net/ for the orginal idea). Make the rest publically
accessible, but with the actual email addresses obscured.
