You can enable debug mode with the SMTPDebug property, e.g.:

$mail = new PHPMailer();

A permission denied error message using fsockopen() suggests that the user PHP runs as is not allowed to open a socket. If you'd double-checked that there's no firewall, it's possible that's a SELinux problem :-?
