Spammer is using my domain as return path to spam

[Invisible121]

My hosting provider suspended my service due to "Spamming". I investigated and found out that someone is using a bot to send spam to thousands (or millions) of emails and using its "reply-to" or "return path" as xxx@mydomain.com. (Wherein xxx are random characters and just retains my domain). I found out because I noticed that my GMail received lots of MAILER-DAEMON bounce emails (Around 4,000 in less than a week). Since this is out of my control, how do I protect myself from this in the future? If you've become a victim of this kind of problem before, I hope you can advise me. Thanks in advance!

The best way to protect from this type of issue is never share the emails on non reliable sources.

do not share email. stop temp email service from ur server.

this is called email spoofing, and for the moment there is nothing you can do about it. Just contact your hosting company and explain them the situation. They can verify this and should understand the situation
