Here's why: every user has to define a "mailkey", which is some phrase that is present in his .sig. Nowadays is pretty common to get replies quoting the full message. ASK delivers (and also whitelists, if so configured) mail containing your mailkey. Even confirmation messages are customizable and multi-language. Unreplied messages are queued (you can get the listing by email, process each of them individually and edit black/white/ignore-lists, all by simple emailing to your own account). The current beta version would connect to the senders' SMTP and see if the reply address is valid, prior to even queueing and challenging a message from an unknown address. Also, I don't know why this guy is so upset. Only thing he has to do is reply. Not really that hard. Is like complaining about security checks in a building, even though you were invited. Regards. Fernando.
