Forward error Relay domain

Question / Problem

In the eventlog I see the error "Relaying not allowed for yourdomain.com" and I don't receive any mail in my inbox. What is wrong?

Answer / Solution

Your Exchange/SMTP server is not configured to receive mail for yourdomain.com. From your Windows Start Menu, select Start | Programs | Microsoft Exchange | System Manager. There select: Recipients | Recipient Policies | Properties. Click on the "email Addresses" tab, under Generation rules, select SMTP, and then click Edit and change the value to "@yourdomain.com". Please also make sure that the email addresses of all users are specified in their Active Directory entries on the "email Addresses" tab.
