I seen this a couple of times before, mainly in tmy junk mail, and email sent to me by me, with what looks like spam, sometimes threatening emails.
I changed my password, I use Samsung Tablet.
I look at my sent items and it doesn't show any sent messages to myself or anyone else I don't know.
I checked my online activity and it doesn't show any suspicious ip addresses.
When I click on reply, it does not show the email address, just a name title.
Is this some clone or something?
I changed my password again…
