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.
Sender ID/SPF has nothing to do with the green batch. – bzeaman – 2017-04-19T11:19:43.477
@bzeaman: Things might have changed since when this answer was given in 2010. Please give more details about why you think so. – harrymc – 2017-04-19T15:41:49.803
The answer below contains the right explanation for the green batch (https://superuser.com/a/220105/564772). I've worked with tons of email setups, and Windows Live never showed any of these with this green icon. Without SPF the mail will be marked, without Sender ID nothing will change. Sender ID appears to be obsolete and does not affect current mail systems, in my experience.
