Hey There

I am facing issues… Yet My VPS Provider Mailed me for There is Too Many Outgoing Connection Request to my Server port 25. I am using CyberPanel. I know its not fault of CyberPanel. I need help to configure like this way so no one without me can send email

  1. Stop Any Emails ( Even PHP Mailer ) From sending emails without authentication
  2. Stop UnAuth Email or Authenticated Email but Not Manually Whitelisted by Me to Send Email

Is this 2 Possible? Let me know. This can help many people struggling like me

You are not the only one experiencing this and a post reporting this was created but the team will not do anything until there is an outburst.

But it is causing me getting trouble like My VPS Provider is mailing me that I am about to reach Maximum Outgoing Connections even I am not sending mails. And I am also getting marked as spam in Spamhaus

I never stay wait for someone to help me. I will self find it, still if any Legend can help me it would be great appreciative
