Indeed, that is exactly what many of them do now -- just send spam to every possible address, and know that some small percentage will accidentally hit a real account. You can help them quickly identify valid e-mail accounts if your mail server does interactive validation of recipient addresses. Doesn't take very long to quickly spin through hundreds of addresses per minute (or second) and find out who all the various valid e-mail addresses are at your site. They can then make money by selling that list to other spammers. -- Brad Knowles, "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
