Exchange 2010 External Relay

Hi,

We have an Exchange 2010 server hosted internally which our end users connect to directly via Outlook Anywhere. Any external email is then sent via a smart host send connector to our Mail Marshal system where it is then sent out to the big bad world.

Our company website is hosted externally by another company and they have asked to be able to send email from a particular address within our fqdn through our Exchange server.

At the moment I have created a custom Hub Transport receive connector and limited it only to the external IP of our web host. I have also changed the port from the default 25. Reading various articles on the net suggest that I need to set the Authentication to Externally Secured (for example, with IPsec) and to set the Permissions groups to Exchange servers. Is this correct.

I need the connection to be secure and I need them to login with a username and password. I cannot for the life of me fathom out where I set the login details and how to tie it to an Exchange Mailbox.

The web server will be used to send out Marketing emails.

Thanks.

John

Thanks.
Simon, I have a similar scenario to the original post - please can you advise which options on the Receive Connector Authentication & Permission tabs, to allow the 3rd party to use AD credentials??
