We have a Windows Server running PLESK 11 and MailEnable 6, however it does not matter what we do, we cannot send mail to a non local address, it always returns a 503 Error saying it needs 'authentication'.
Before anyone replies asking if Outlook is configured correctly on the Desktops, I am an MCSE and specialise in Building Servers and Secure Mail. There is nothing wrong with MailEnable, we can ping and telnet into the post office and mail boxes. It will send mail to a local address but not a non local address.
