How to hide my DO ip address in received gmail headers?

Did you restart apache2? <pre>sudo service apache2 restart</pre>

Yes i did it, restarted, trying two new user registration, but all the notification email headers in mysecond@gmail.com and mythird@gmail.com still the same: <br> <br>Delivered-To: mysecond@gmail.com <br>Received: by [notmydropletip] with SMTP id xxxxxx <br>X-Received: by [notmydropletip] with SMTP id xxxxxx <br>Return-Path: admin@inamasei.com <br>Received-SPF: neutral … <br>Authentication-Results: mx.google.com… <br>Received: from localhost ([xxx.xxx.xxx.xxx]) <-my DO ip address <br> by mx.google.com with ESMTPSA id xxxxxx <br>To: mysecond@gmail.com <br>Subject: [inamasei.com] New User Registration <br> <br>

I don’t think there is any way to hide it since Gmail passes it over. You can try using a SMTP service such as <a href=“http://mandrillapp.com”>mandrillapp.com</a> (edit msmtp’s config to match your mandrill account’s SMTP credentials).
