It started October 5th. I get a email that is returned due to no such address found. The email is from googlemail.com and I am getting it approximately every hour. The email address that doesn't exist is "you@domain.net". It isn't being sent from my email app and that email address isn't in any of my contacts. I've attached a screenshot. Does this mean that someone is using my email? Does anyone know who to talk to to stop this? I've routed it directly into spam so it isn't irritating, however I'd still like to stop it. I use Maildroid Pro for email and Verizon is my carrier. Thanks in advance for any help.
