As for why anyone would worry about the carrier... maybe it was sent through one of the Clinton private carriers? And maybe the system ITSELF was designed to substitute “webtv” for it’s own identifier?
Well, I might have to correct myself as someone wrote me and said they still use the WebTV address and it “goes through Outlook”! Does Outlook show the WebTV addy - I don’t know!
Lol, haven’t been posting here for a year and then may have messed up. I did post to one of you about people ‘moving’ to Outlook.
