We are running Exchange Server 2003. We have one server. All of our users run Outlook 2007. We recently started getting the errors listed below. No configuration changes were made on our servers.
It is my understanding that I can get these messages if I was attempting to use our server to send email, but my account was another domain. Example: My email address was me@anotherdomain.com, but our Exchange Servers was OurRealDomain.com. The server would not relay the message on. Or if the domain for the end recipient received an email that was from me@anotherdomain.com, but was sent through exchange01.OurRealDomain.com.
Can anyone clarify the various situations I get these emails? Both when produced from our server and when produced by the final recipients server.
Also, how can I troubleshoot this? I have tried using telnet from our exchange server to the servers in question without error.
 As basic as possible would be helpful. I am at an intermediate level but some reason I am having trouble grasping this.

<ourserver01.ourdomain.com #5.5.0 smtp;550 relay not permitted>

ourserver01.ourdomain.com #5.7.1 smtp;554 5.7.1 <jfluentez@recipientsdoamin.com>: Relay access denied>

< ourserver01.ourdomain.com #5.7.1 smtp;550 5.7.1 bmoyeri@OTHERrecipientsdoamin.com>... Relaying denied>

You are correct. Basically a relay is when an email is generated from a user/email address that does not belong to your Exchange organisation to another Exchange organisation.

The accounts sending the messages, are they regular users? Service accounts? Etc?

They are regular users. They get the errors only sometimes. They can email a user, get the error, email again, and it goes through....

Can you confirm you have a single SMTP Virtual Server and a single Connector?
