I have exchange 2003 standard running on server 2003 enterprise. I can send mail from the domain but cannot recieve any. I have checked to make sure the MX record is correct and that I can log in through TELNET. I have also checked the recipient policy to ensure that it has the correct domain. On the SMTP Virtual Server, it is allowing Anonymous Access to the mail server. I have also checked in AD that each user has firstname.lastname@example.org as an email address. When I send a message from GMail.com i get a message stating "Delivery Status Notification: Delivery to the following recipeints failed" and continues to list the email address that I sent to.
