My email address via. Comcast is set up so that there is no name associated with it. I should be receiving replies from recipients of my messages showing my full email address rather than a display name.
But recently I have received replies from someone the To line of which read as a display name rather than the full email address.
The recipient did not manually create a contact for me set up that way, which would have explained why it changed.
The display name that was populated corresponds to a username that I have used on a Google account, and the Google account is linked to Facebook.
Is it possible that Windows Live Mail interfaced with, say, Google at the time my correspondent replied to my message, andautomatically changed the full email address to that username?
