Exchage 2010 send through another program

I have a CRM product that needs to send emails outside of our network through our Exchange 2010 Server. When I setup in the CRM program I get this error. "Error: 504 5.7.4 Unrecognized authentication type"

Do I need another receive connector? Special user account setup?

It isn't a Send Connector that you are using, it is a Receive Connector. To send email through Exchange it has to be received by Exchange. Then it goes out the same way as before to send email.

The best option is to have a dedicated connector.

An easy and common way of making it is using anonymous permissions for your send connector (For best security you can créate a new connector and configure this permission and allow Access in the connector just to your CRM servers that are used for sending emails). After making it dont forget to configure your application without authentication (annonymos)

In more security environments you can control it by using an account, but it will requiere a deeper configuration

I do not see a place on the SEND connector to setup anonymous or permissions. What am I missing?

If in understand correctly we talk about an application that is supposed to send SMTP messages.

If this is the case, you should make a new receive connector that has IP range/address of the CRM and check permission tab - make sure anonymous is enabled.

You can use the default one but I don't advise it as this is a security issue.
