Its called a pink contract at least part of it is. The pink technically allows spam to pass not blocked by the ISP or the email server. $39.95 per million from Bulk Email Superstore http://www.americaint.com/bulk-email-lists/buy-email-lists.html. What the cost for purchasing the email from Google is unknown but the exstraction of emails from the web is easy and combinations of emails to a specific address type such as @yahoo.com can if a pink contract is place will garner a refined sort of viable emails. To narrow that down to specific demographics is even easier. Go to http://www.expedite-email-marketing.com/Stock_Investor_List.htm or other sites. So the rich worker bee will be spamed or have their email harvested for other purposes by process of elimination and culling by geographic demographics.

I realize that you wanted the actual emails but you first need to know the email and the person attributed to it. Once that is achieved you can selectively request the information from the people managing the e-mail server. Purchasing emails contents (the actual emails sent and received) could be tricky and I doubt anything other than one off requests exist but in case you find someone I have a list I'd like checked.

OK, so one would have to figure out the cost of the one-off individual research query directed to the mailserver ISP. Good point, I never thought of going to the repository. Another possibility is that eBay might be a better place to price ones head than a google advert. I can save you the trouble of paying for that info, she's with me now. Might be a great business opportunity here.

If it's a risk management question, shouldn't you be valuing it at replacement cost?

(thinks...) could be...

I think I am assuming that it is hard to value it from my point of view. Instead, I'm valuing it from the attacker's point of view.

If I can do that, then I am faced with a binary choice: if the value to the attacker is higher than to me, I just sell it at that price. If the value is less, I protect it. I don't actually need to value it precisely, just know if it is more or less.

(Actually, I am looking at this for another reason - in discussions on email encryption, it has been asserted that the benefit of protecting most email is zero. I think it is above that, but I can't show it. So I'm looking for a value number.)

The software code which provides real authentication, within a device that provides the individual the ability to reliably compose a message, is worth more than gold. It is better than the entire edifice of banks, or the systems of title to land or stock ownership in governments and treasuries. So where the HELL is it, and what's taking so god damned long? We should get 50 or 100 patriots together, rent a barn somewhere and build it. Not for the money, but for the principle of it. Listen to the whole hour: http://www.radio4all.net/proginfo.php?id=18069
