Boxtrapper seems a good idea to me but one thing to watch.
I tested it by making a white list and using my Wanadoo email account (which I had NOT added to the white list) to send an email to the Boxtrapper protected address.
The verification mail was properly sent - but my Wanadoo account classed it as spam and dumped it. So had I not been watching for it, I'd never have received the verification request, or known that my original email hadn't got through.
Just a point to keep in mind, it may apply to AOL and other big ISPs as well.
This makes its use iffy for me but I can't see what could be done.
I think the problem may be that the verification email subject contains a long number and # and that may trigger the ISP 'spam' filters.
