Today I received an email from Ebay which I was reading in my Windows Live environement.
I noticed a small green icon before the message, and at the top of the reading pane.
The popup of the green batch says 'This message is from a trusted sender. To help protect you from phishing scams, we double-checked that it's safe'.
Does anybody knows how this system works ? Why does Live displays this icon ? Do we need to add some headers to our mails or let our server be known as a non-spam trusted mail server ?
We are sending mails to hundreds of named customers and would like to be sure that these mails are not listed as spams.
Thanks in advance.

Up till now the hackers have succeeded in breaking each and every protection. So I would say that the Windows Live message is a positive indication, but that one should still use normal caution.
As regarding what you should add to your own emails, see The Sender ID Framework :
In the best case, all this is already taken care of by your ISP.
But it is best to make sure.
In any case, the safety this method gives is based on the DNS system, which we know can be hacked; on the ISP, which we know may be rogue; and on the contents of the email, which can be forged. So Sender ID is surely hackable.
