I don't know where to start. Please help me with answer or direct me to where I can be helped.
I am getting about 20-30 of the following every day. I am told that someone is using my email address as a return address in doing spamming. (My domain is registered with 1and1 and hosted with Lunarpages).
I would like this to stop. How can I get this to stop, short of cancelling that email address? Thanks.
The message I'm getting is:
