I have a distribution list setup in my exchange org. that includes two external contacts and some internal employees. Now if someone internally sends an email message to the distribution list everyone on gets the email as expected. However when an external person (say from hotmail) sends an email to that same distibution list only the internal employees on that distribution list receive the email... Is this normal?
I used exchange message tracking and I see the message coming in and when I look details of the message tracking I don't see the external contact listed in the exchange header. I have confirmed the distribution list is setup to accept mail from everyone.
All A Records, Reverse lookups, and MX are valid.
