Recently I have been getting returned mail delivery errors stating that "somerandomname(at)mydomainnamehere(dot)com" could not be delivered, because the recipient doesn't exist. I know for a fact that this is not my doing, because I use, and am the admin of the google apps account that creates email accounts for my domain name, and none of the accounts that are sending these emails are real. So I am guessing someone is spoofing their email address and using my domain name to do it. I looked at the returned mail email error, and it said the email was mailed-by host102(dot)host102-server(dot)com.
There was a file attached to the error message that apparently gives me more information on the person who is doing it. Their name is apparently Phoebe Henry, and the reply to address is Annette Thompson.
I won't attach the file here, because it has this Annette person's email in it. If someone wan'ts me to though, I can remove their email, and then attach the file here.
any help on how to put an end to this would be much appreciated. I don't want this person/people to send an email to a real person, and have me take the blame for it.
