Spammer using my site's email to spam

    In the last few day i start receiving bound back email block by spam filter. The sender is a email address with company domain (but the address doesn't exist).

    I check my email log, no outbound mail. And the situation is getting more serious as i get hundreds of mail every hour.

    Anyone had similar situation or know how to stop it?

    Since the fake address doesn't exist, the mail went into the catch all box (info@ccaus.com)

    Its very simple.

    The mail was sent by gator161.hostgator.com

    the ip of sender is 163.130.151.200

    Contact hostgator with the email headers as you posted above. They will be only the one who can resolve it;)

    Or they're just using your mail-address as a from address and you get all the non delivery reports. If so, your pretty much f***ed. Wait a few days and they usually change to another address.
