Trying to setup exchange 2003 to allow users to relay mail through the exchange server. We have 2 exchange servers at 2 different locations for 2 different companies. What I'm trying to accomplish is have company A attached to outlook as a exchange account then have company B attached to outlook as a pop 3 account.
Currently I'm only trying to accomplish this for only one user, the vice president who needs to send and receive emails from both companies through his outlook profile. He has an account on both domains and can authenticate via outlook no problems. The issue that I'm having is when he tries to send an email from the pop account we get a message back from the system administrator:
Your message did not reach some or all of the intended recipients.

The following recipient(s) cannot be reached:
'user name' on 5/26/2009 12:33 PM
550 5.7.1 Unable to relay for email@example.com
I have given him relay permissions to the SMTP connector so I believe he should be able to accomplish this.
During my testing I created a test profile on another machine where i mimicked the same configuration. Test user is attached to local exchange account to company A and company B's pop 3 account is then added as an additional mail account. Through the test account I am successfully able to send emails via the pop account but I am noticing on the receiving end the senders address is showing as user@companyA.com not company B.
Am I going the right direction in my configuration or is there a better way to accomplish this? I have previously been able to do this with exchange 2007, but am having difficulty doing it in SBS 2003.
