I have now searched all over for fixing my issue but no solution. My dev gaveup long ago, so help anyone..

I have a integrated ticket system sending automatic email to user and admin when create and reply. The email header goes fine out and email ticket template also fine. But the Message included keep have this issue with line space replaced by \r\n.

It run on Linux server
Here is email header
$config['email_headers'] = "MIME-Version: 1.0\r\nContent-type: text/plain; charset=iso-8859-1\r\nFrom: \"sitename\" <noReply@mydomain.com>\r\nReply-To: \"NoReply\" <noreply@mydomain.com>\r\nX-Priority: 3\r\nX-Mailer: PHP 5.4";

Here is the function file part
# Email to user and admin code starts here
$sql = "select * from ".TABLE_PREFIX."emailtemplate where type='ticketreply_send' LIMIT 1";
$sth = mysql_query( $sql );
$emailtemplate = mysql_fetch_array( $sth );
$Ticket_Email = $emailtemplate['content'];
$Ticket_Email = str_replace( "[[SITE_TITLE]]", $this->config['title'], $Ticket_Email );
$Ticket_Email = str_replace( "[[ticket_id]]", $ticketId, $Ticket_Email );
$Ticket_Email = str_replace( "[[message]]", $message, $Ticket_Email );
$Ticket_Email = explode( "--- Email ---", $Ticket_Email );
$Subject = $Ticket_Email[0];
$Message = $Ticket_Email[1];
mail( $user_info['email'], $Subject, $Message, $this->config['email_headers'] );
mail( $this->config['private_sys_email'], $Subject, $Message, $this->config['email_headers'] );
# Email to user and admin code ends here
