PHP5 - Verifying a secure mail is secure

Posted on 16th Feb 2014 by admin

I need to send an e-mail from a form to a external department and because it contains personal customer information, it must be secure.

I've set up an SMTP mail instance to send it off and pointed it at the secure server using the second implementation found on this website.

How to Send Email from a Script Using SMTP Authentication

The e-mail gets sent, but is there any way to verify it is being sent securely or can I safely assume that because I'm sending through SMTP, it won't go through unless it's secure?
