MS Exchange 2007 Distribution List
Hi All,
I have created a new distribution list on my MS Exchange 2007 SP1 server.
Internally it works fine, however I keep getting external mails bounced back with the following error (some details changed)
Help Please.

Hello techmiss,
When setting up Distribution Groups in Exchange 2007, there is a silly option that is set by default that will prevent sending to that group from external sources. I suppose it’s a security feature, making you manually enable that address to be accessed from unauthenticated users, but it can be a head scratcher if you’re not looking for it.
So, after you create the Group, right-click on it, then go to properties. Click the Mail Flow Settings tab.
Select Message Delivery Restrictions, then click the properties button.
Uncheck the box that says "Require that all senders are authenticated", and you should be good to go.
Hope it helps.

find the group right click properties -> Mail flow settings -> Message delivery restriction and UNCHECK 'require that all senders are authenticated'
