Exchange 2010 Distribution Group Not Receiving Outside Mail

I just created a new Distribution Group and added some members.

From an internal user, I can send an email to the group and all members receive a copy of that email.

From the outside, I send an email to the email address but it never gets delivered to the members, even though I do see it in the Exchange 2010 message tracking explorer.

The queue viewer shows no messages in queue.

I don't see any errors in the Windows Event Viewer.

I wonder what is happening to these emails.

Thanks.

When you create any distribution list with Exchange Management Console - EMC or Exchange management Shell - EMS in 2007 by default Sender Authentication is Enabled to prevent unwanted messages from spam and from outside domain, this is by default in design...

 

You need to disable it to get email from outside.

 

From EMC: Recipient Configuration -> Distribution Groups -> Select a group -> Properties -> Mail Flow Settings -> Message Delivery Restrictions -> Properties -> Untick “Require that all senders are authenticated”
