mail() PHP always use user@localhost.local domain and my server reject each mail-CodePudding

mail function of my php scripts always use user@localdomain in the from header. As a result my new SMTP relay provider bounce the mail becouse the localdomain isn't resolvable. This is an example script:

<html>

   <head>
      <title>Sending HTML email using PHP</title>
   </head>

   <body>

      <?php
         $to = "[email protected]";
         $subject = "This is subject";

         $message = "<b>This is HTML message.</b>";
         $message .= "<h1>This is headline.</h1>";

         $header = "From:[email protected] \r\n";
         $header .= "Cc:[email protected] \r\n";
         $header .= "MIME-Version: 1.0\r\n";
         $header .= "Content-type: text/html\r\n";

         $retval = mail ($to,$subject,$message,$header);

         if( $retval == true ) {
            echo "Message sent successfully...";
         }else {
            echo "Message could not be sent...";
         }
      ?>

   </body>
</html>

CodePudding user response：

Open /etc/hosts

Try to add your domain between 127.0.0.1 and rest of entries

The mail server picks up the first entry

So if you set for example:

127.0.0.1 exampledomain.com servername localhost localhost.localdomain ...

As well you can check if your smtp server its using the proper host name.
