PLEASE HELP!!!
Has this happened to anyone?
I received 2 emails this morning.
One from a "new user registration" for my website.
Then, a "mail delivery failed" which is this:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

vigil@2032battery.org
SMTP error from remote mail server after DATA:
host smtp.europe.secureserver.net [188.121.52.56]:

------ This is a copy of the message, including all the headers. ------

I removed most of the coding in this as I have no idea if it routes to my sensitive info on my site.
I fear someone hacked me?
Am I right?
UGH!!!!
