Thanks jpowers,
I did all the changes above, yet my osTicket is still not sending emails. I have tested the server with the code below, and the email goes fine - so I am stumped.
<?php
$to = "me@myemail.com";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "someonelse@example.com";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
I have checked all logs and can't find anything of significance.
Any help would be greatly appreciated.
Mark
