Suppose this Hypothetical, what if the message is for a server host. The assasins are hackers that have been paid to shut you down and they never miss. The way you send that message is by planting a bot on their server and send a few thousand or million emails that say that, arriving on shore is when they'll access begin the process(the whole thing a cryptic message not intended for you). The other is just to get people to respond so you can sell their email addresses. Either way it's rotten bussiness. But, the money in the assasin for hire is about the amount you might get for shutting down a major server or should I say not shutting it down. Who realistically thinks they'd bring that much? Really, what are you a banker or a super ninja?
