Hi!

I get error: 550 5.7.1 Unable to relay

And from the app:
    DllDate: Jan 29 2008
    Username: Administrator
    Component: ActiveX
    Using existing/open SMTP connection to send email.
    subject: TEST MAIL
    reversePath: user1@domain.no
    recipients:
      550 5.7.1 Unable to relay
      Fail

The thing is that i have a app server that sends mail, how should the hub transport be set up?
