    I'm getting this error message from users trying to register through our guest provisioning:


    Script:    /guest/self_registration_guest.php
    Function:  NwaSmtpSendMessage
    Arguments: array (
      'rtn' => array (
        'error' => 1,
        'message' => 'Failed to add recipient: [SMTP: Invalid response code received from server (code: 550, response: No such domain at this location)]',
      'args' => array (
        'recipient' => '',
        'subject' => '',
        'message' => '
        Visitor Access
        Password: 485503
        Expires: 2015-07-23 09:43:34
        Powered by Aruba',

    It doesn't seem to matter which carrier is selected. All have failed that I've tested.

    Oddly enough, when I go into the configuration and send a test message it sends right away. 


    Any thoughts?

    In 6.5 we don't by default trust the smtp severs cert. You must add it to the trust list. There is a trick to do it with a context server but I'm not where I can post a how to.
