Review email spam issues on your server
All of our servers have the ability to send mail by default, but the server can also be used to send SPAM without your knowledge. This is typically due to a compromised email password or with a script on your site(s).
Signs of a SPAM issue
- Your daily amount of allowed outgoing email relays (5000 by default) is regularly being reached.
- You can't send mail at all, and receive bounceback messages like "Message Delivery Failure" or "Access to this mail system has been blocked."
- The outgoing mail queue in WHM Mail Queue Manager or Plesk Mail Queue is full or not processing.
Investigation
SPAM can quickly bring your business to a standstill. If you think your server is sending SPAM, it's important to quickly identify, resolve and prevent any further issues.
