Exchange 2010 - Relaying Externally

Ran into this issue earlier today.. a few weeks ago while working with our DBA in getting internal relaying setup for some Oracle servers I must've broke the external relaying they also performed but since that is just an occasional thing it was missed.. until today.

So in order to configure a Receive Connector for External relaying you must run the following command via the EMC:

Get-ReceiveConnector "External Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "ms-Exch-SMTP-Accept-Any-Recipient"

So create your Connector choosing Custom, clear out all the checkboxes under Authentication then Finish.  Once created run the above command and you're golden Pony Boy.
