Finding and Fixing Spam Abuse on Your Server
If you suspect hackers have abused your server to send email without your knowledge, we have tools to help you clean up the server and help prevent the same issue from happening again.
The tools you can use depend on your operating system, control panel, and MTA (Mail Transfer Agent). If we don't have tools for your server's configuration, we recommend looking for other resources.
We recommend ensuring your relays are closed. For more information, see Testing Your Server for Open Relays.
