Spam sent from my server

Good afternoon,

I was encountering a problem with sending spam via my email [email protected], I don’t know why it was created in the panel, I deleted it and that solved my problem, I would like to know how I can activate email sending to outlook and gmail , having the CSF smtp_block option activated, I would like a detailed explanation, as my emails are returning to these providers…

Thanks

Hello @moskatus

  1. To ensure that email can be sent even with smtp_block enabled, you should configure allowed ports (like 465, and 587) in the CSF configuration
  2. Ensure TLS is enabled imn postfix /etc/postfix/main.cf. Any changes done to this file warrants you to restart postfix daemon.
