Contact form producing Error 500 on Godaddy

Hello! Thank you for your fantastic template! I hope you can help me figure this out.

My site http://www.ereaton.com is hosted on Godaddy and I've been getting an Error 500 when attempting to submit the contact form (which is at http://www.ereaton.com/contact.html.

I learned through googling, this forum, and the docs that I needed to configure it for SMTP. I've added the following to sendemail.php.

$mail->IsSMTP();
$mail->Host = "mail.ereaton.com";
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->Port = 25;
$mail->Username = "ed_eaton@ereaton.com";
$mail->Password = "(password)";

Do you have any thoughts what could be causing the error and how to fix it?

Thank you!

Thank you for the prompt reply!

I changed the port to 465. Unfortunately that doesn't seem to have solved the problem.

I've attached the file here with the password removed. Perhaps there is something else I've missed or messed up?

Thank you again for your help.

Apparently I could not upload that file for security reasons. Here's what the top of the file looks like.

<?php

require_once('phpmailer/PHPMailerAutoload.php');

$toemails = array();

$toemails[] = array(
'email' => 'ed_eaton@ereaton.com', // Your Email Address
'name' => 'Edward R. Eaton' // Your Name
);

// Form Processing Messages
$message_success = 'I have successfully received your message and will get back to you as soon as possible.';

// Add this only if you use reCaptcha with your Contact Forms
$recaptcha_secret = ''; // Your reCaptcha Secret

$mail = new PHPMailer();

// If you intend you use SMTP, add your SMTP Code after this Line

$mail->IsSMTP();
$mail->Host = "mail.ereaton.com";
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->Port = 465;
$mail->Username = "ed_eaton@ereaton.com";
$mail->Password = "password";

Thanks SemiColonWeb. Your update seems to have fixed it.

Note for future readers - I needed to remove the SMTP elements of my code for it to work correctly.
