550 5.7.1 Unable to relay for ...


I want configure mail server in the Epo 4.5. I ordered the name of SMTP, port, adress, saved changes, then enter adress of the recipient and press the button to test, then received message: An error occurred while trying to send the test email. 550 5.7.1 Unable to relay for server@mcafeedlp.local.

Where server@mcafeedlp.local - my adress.

Mail server is running. I can receive and send letters.

Tell me please, what I doing wrong.

You're posting mail questions in the encryption forum for a start I'll move it somewhere more appropriate.

Is the ePO's IP address allowed to relay to the exchange server?

You should also look if the sender mail address you are using for ePO's mail must exist on exchange or not.
