PHPMailer Installation/Test ERROR MESSAGES

[SystemOverload]

Hey

 

I'm on PHP 5.3.4ish.  I've recently started using PHPMailer, but when testing it, end up with an "Could not instantiate mail function." error.

 

Does anyone have any ideas?

 

My files are laid out as below:

 

/emailtest.php

- Calls fn_mailer("test@live.co.uk","Test Email Recipient","Subject","BODY")

/includes/functions/fn_comms.php

- Contains function fn_mailer(), a simple wrapper that accesses the PHPMailer Functionality...

/includes/functions/phpmailer/class.phpmailer.php

/includes/functions/phpmailer/class.pop3.php

/includes/functions/phpmailer/class.smtp.php

 

fn_mailer()

function fnMailer ($varToEmail, $varToName, $varSubject, $varBody) {
// - -- --- Wrapper for PHP Mailer Class Interface ------------------------------------
require_once 'phpmailer/class.phpmailer.php';

$mail = new PHPMailer(true); //defaults to using php "mail()"; the true param means it will throw exceptions on errors, which we need to catch

try {
  $mail->AddReplyTo('support@test.info', 'Support');
  $mail->AddAddress($varToEmail, $varToName);
  $mail->SetFrom('donotreply@test.info', 'Admin');
  $mail->Subject = $varSubject;
  $mail->AltBody = 'To view this email message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
  //$mail->MsgHTML(file_get_contents('contents.html'));
  $mail->MsgHTML($varBody);
  //$mail->AddAttachment('images/phpmailer.gif');      // attachment
  //$mail->AddAttachment('images/phpmailer_mini.gif'); // attachment
  $mail->Send();
          echo "Message Sent OK</p>\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}
// - -- --- END OF WRAPPER ------------------------------------------------------------------
