Allowing application servers to relay off Exchange Server 2007

Hello,<br />
<br />
I have done a swing installation of Exchange2010 in an exchange 2003 organization.<br />
The exchange 2003 server works as an internal relay for various application servers and so on. For relaying we use an mailtest-user.<br />
So what do I have to do in Exchange to get internal relaying working with authentification.<br />
<br />
I have 2 trusted authorized domains:<br />
test.com<br />
test-online.com<br />
<br />
test.com is the name of the windows domain.<br />
test-online is the name of the email-domain. We have no edge server and the exchange is not published to the internet.<br />
We have mailboxes at an external provider which get collected by popcon.<br />
<br />
So what I would like to do is sending internal mails via SMTP (application server) to internal addresses.<br />
<br />
I always get an error that the exchange 2010 dropped the connection because he doesn`t like the sender name.<br />
<br />
What do I have to do?<br />
<br />
Thanks a lot
