  Hi, This is a pure case of spamming. To avoid this, the best way is to disable the PHP mail function and use SMTP authentication in the PHP mail script, so the mails will be send through PHP script, but it will actually authenticate the mail server properly.

  Hello, The following document is a good place to start: How to Prevent Email Abuse - cPanel Knowledge Base - cPanel Documentation In particular, note the section titled "Experimental: Rewrite From: header to match actual sender". Thank you.
