That's likely a misconfiguration of the apple Mail client.

    Preferences->
    Accounts->
        Outgoing Mail Server (SMTP)-> (Menu item)
        Edit SMTP Server list -> ("Advanced" view)
            * Use custom port (enter 465)
            * Use Secure Sockets Layer (SSL) (check)


            Configure the correct username and password!


Test with

    Window->
        Connection Doctor

This sure looks like a client-side issue. Or perhaps GnuTLS is
misreporting the client disconnecting as "unexpected length".

MacOS/X will generally prompt to accept self-signed certs, which
end up on the keychain as trusted for the site in question (admin
password required).
