Allowing AuthAnvil to send email on SBS 2008

If you find that during the System Test in the AuthAnvil Manager that you always fail to connect to the SMTP server, it is usually because AuthAnvil can't talk to it. On an Exchange 2007 box, that is USUALLY because you have not allowed anonymous users to send email. Since AuthAnvil does not use authenticated SMTP, you will need to grant the anonymous user permission on the Hub Transport.

You can do that by following these steps:

1. Open up the Exchange Management Console
2. Expand Server Configuration
3. Click Hub Transports
4. In the "Receive Connectors" tab, right-click on the "Default <servername>" and select Properties. (ie: "Default CONTOSO")
5. Click the Permission Groups tab
6. Check Anonymous users

At this point, if you rerun the System Test, you will find you can properly send email.

Authenticated SMTP support is on our TODO list. Until then, you will need to enable Anonymous User to the Permission Groups if you want to use Exchange 2007 to send out your AuthAnvil enrollment, token management and security alert emails.
