I just started receiving bounced emails to my sbcglobal.net account. These have a return address with random characters @ my website address, e.g., xzy123@helloworld.com. It looks like someone has hijacked my website to send spam. The message content is readable, but very random, text. The recipients are also random, with many being sent to foreign countries. There are also a number of them being sent to “dummy@bellsouth.net”. Maybe someone is trying to flood them?
I’ve left a message for my web host but am continuing to research on my own. Any suggestions would be greatly appreciated.
