How to Verify that Your SMTP Virtual Server Allows Anonymous Access
Topic Last Modified: 2005-05-24
As you know, other SMTP servers on the Internet expect your SMTP virtual server to connect to them anonymously. Remember that if you do not permit anonymous access on your gateway servers that accept Internet mail, other SMTP servers on the Internet are unable to send mail to your organization.
Before you perform the procedure in this topic, read Connecting Exchange to the Internet.
The following permissions are required to perform this procedure:
Member of the local administrators group and a member of a group that has had the Exchange View-Only Administrators role to view configuration, or the Exchange Administrators role to change configuration, applied at the administrative group level
Right-click your SMTP virtual server, and then click Properties.
Click the Access tab, and then click Authentication.
In Authentication, verify that the Anonymous access check box is selected.
