    We’ve just implemented a new fresh install, alle server roles installed seperately!
    Edge is in the DMZ and subscribed to Hub in our Domain.

    I can Receive with POP3 and send internally with SMTP thru port25!
    When i try to send outside the company, i get an error message 5.7.1 Unable to relay!

    When i give the receive connector on the edge, the permission:

    add-adpermission -id “Default internal receieve connector servername” -user “NT AUTHORITYANONYMOUS LOGON” -extendedright “ms-exch-smtp-accept-any-recipient”

    Then i’m able to send outside! But this makes me computer an open relay system since i gave anonymous the permission to send to anyone outside the company!
    I have tried this using the “NT AUTHORITYAUTHENTICATED USERS” but with this option i need to create the account also locally on the EDGE!! This doesn’t make sence since i thaught that ADAM took care of this?

    Help is really appreciated!!!
