I am trying to create a blackhole (noreply) mailbox in exchange 2010. I want a legitimate email address that will evaporate any email that gets sent to it.
I have been googling and the answer I have come up with is to create a distribution list with no members and give the noreply email alias to that group. This work great for evaporating email, but I cannot give a user permission to 'Send As' a distribution list.
Right now I have a web app that authenticates with my exchange server as WebApp@myDomain.com. It trys to send email out as noReply@myDomain.com. My exchange server gives a 5.7.1 error. Client does not have permissions to send as this sender.
Does anyone have any idea how to relay with a blackhole email address?
