title: How do I allow an email discussion list in MOSS to collect messages from any email sender
body: <p>I have a Sharepoint discussion list that belongs to an Exchange list with the idea that it will be able to archive discussions on that list and make them generally accessible, searcheable and so on.</p>
  
  <p>The problem is that although I have checked the "Accept e-mail messages from any sender" option on the discussion board, it still appears to only be seeing emails from members of the domain, nothing sent to the list from outside gets picked up by the Sharepoint site.</p>
  
  <p>Any suggestions as to what else I have to do?</p>
