All users can receive e-mail that is sent directly to them from the Internet. A distribution group named WebResponse is configured to accept e-mail from all users. All corporate users can send messages to the WebResponse distribution group by using Microsoft Office Outlook. All messages that are sent to the distribution group from the Internet are rejected. You need to allow e-mail from internal and Internet users to be sent to the SMTP address of the WebResponse distribution group.
