cannot send mail using PHP beyond domain

1st file, uses 2nd file [includes it] place both in same folder for simplicity, move one to /includes/ if you want to be tidy, then change path.

save the first file as 'test_auth_mail .php', or some memorable name

Code:

<html>
  <head>
    <title>Simple SMTP mail test</title>
  </head>
  <body>
Testing SMTP mail sending ...
<br><hr><br>
 
<?php
include_once('auth_mail.php');
$user_email = "somebody@somewhere.com";
$from = "legituser@yourdomain.com";  // Needs a valid email address able to use SMTP
$subject = "Test Email";
$message = "This is NOT a fluke !! IT REALLY WORKS !!";
authSendEmail($from, 'yourdomain.com', $user_email, '-', $subject, $message);
?>
<br><hr><br>
Test completed, hopefuly IT WORKED for you too !!  :)
<br>
If not then double check that you setup the domain, username, password, etc correctly
</body>

save the second file as 'auth_mail.php' , or some memorable name, it gets included, make sure the name matches of course

Code:

This really works, I have re-tested it to be certain because it was edited for posting here.

To use this yourself, in place of the more usual .php 'mail()' function you need to replace occurrences of mail() with auth_mail() AND be careful to ensure the order of the inputs, it is NOT identical, so take care OR it will NOT work ...

ie.
authSendEmail($ from, $namefrom, $to, $nameto, $subject, $message)
versus
mail($to, $subject, $message, $headers, $parameters)

NOTE: though this method does work, at least with my setup, there are some anomalies which I think are caused by the Server's rules concerning SMTP. For example only one eMail can be sent to an address at a time, there must be a delay of a few minutes before another can go, in cases where the mail is virtually identical. This makes testing awkward, but I guess it is part of anti-spam protection.

Further problems occur if there are any format mishaps, the mail must be ultra simple to pass, at least on this server. Any fancy formatting tends to break the process and the mail is lost.

This 'fsockopen' method has got my project going forward again, but it is far from simple or totally reliable to implement. There are lots of references to these problems, just Search. Send a PM if you get stuck, I will try to help if there is time.
