When you try to add a new Simple Mail Transfer Protocol (SMTP) address to the Microsoft Exchange 2000 Server default recipient policy, you receive an error message that is similar to the following:
This e-mail address is not valid. To view details of the error, see the application event log in the Windows Event Viewer on the Microsoft Exchange Server computer.
ID no: c10312e6 Exchange System Manager
The following event is logged in the application event log in the Event Viewer:
Event ID: 1 Source: InternetProxy Description: Unable to generate an e-mail address because the site address SMTP:domain.com is bad. For more information, click http://search.support.microsoft.com/search/?adv=1
Note In this scenario, domain.com is the e-mail address that is being used.
This behavior occurs if the @ symbol does not come before the e-mail address.
To resolve this behavior, follow these steps:
Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
In the left pane, expand Recipients, and then click Recipient Policies.
In the right pane, right-click Default Policy, and then click Properties.
Click the E-Mail Addresses (Policy) tab, and then click New.
In the E-mail address type list, select SMTP Address, and then click OK.
In the Address box, type @ followed by the e-mail address.
For example, @domain.com is a valid e-mail address whereas domain.com is not a valid e-mail address.
Click Apply, and then click OK two times.
Right-click Default Policy, and then click Apply this policy now.
In the Exchange System Manager dialog box, click Yes.
