 Define a sender email address<br>
 sendmail_from = SenderMail@company.com<br>
 </body>
  
<?php
 // Using the ini_set()
 ini_set("SMTP", "mail.company.com");
 ini_set("sendmail_from", "SenderMail@company.com");
 //ini_set("smtp_port", "25");

 // The message
 $message = "The mail message was sent with the following mail setting:\r\nSMTP = mail.company.com\r\nsmtp_port = 25\r\nsendmail_from = SenderMail@company.com";
