Mail returned with an attachment which I have not sent
Posted on 2004-09-21
I have a relatively new domain name which I have not started using yet, Firstserved.co.uk. But today I have a returned email with a .mim attachment from firstname.lastname@example.org saying Returned mail: Data format error.
I have not opened the attachment. What does this mean? I wondered if it means someone is using my email address to spam? If so, how can I make sure this does not happen?
