have you ever sent an e-mail to someonespecial@php.net ?
have you received the [confirm: 3982348978d4b43f8b66d1b6f72ac75426 you@youraddress.com] in reply? yes?
my question is this: how does that whole setup work? it appears to be a nice way to handle the problem of filtering for customer service, and i'd like to try to setup something similar for some of my web sites, or some clients.
i know there was a web-based anti-spam thing which was popular a few years back which worked in a similar manner, but supposedly didn't gain popularity for the reason that one could not confirm that the very company offering the service wasn't trying to get rich off of our private info themselves. however, having a service like this installed on my own server, or my client's domain might be acceptable.
what do you think about it?
