Syste: server 2008
we are having a problem where trying to send emails to a specific domain it is not going out throught the queue, seems like the email server we are sending the emails to is rejecting us with the following error code:
#550 4.4.7 QUEUE.Expired; message expired ##
d when I look into Exchange, I see the following error:
Remote server mailserverdomain.com failed the acceptance test. RCPT TO command: respond -= 500 #5.1.0 Address Rejected
Seems like the mail server we are sending the email to is trying to authenticate the email address sent from with our server but it's getting an address non valid from our server- is that right?

The message expired error is an error generated by Exchange.
The second error is the true cause of the problems. The remote server is rejecting your message for some reason. It isn't completely clear why. It could be some kind of sender validation process, but those aren't that common now. Have you tried a telnet test to the remote server to see if the same thing happens, and so you can see the full SMTP communication?
Does your email come in through another route, just in case they are doing an old sender validation test and cannot connect back to your server to verify things? If you are using an antispam provider and are restricting SMTP traffic in then that might be an issue.

May be your domain have been listed in their blacklist. I think you should ask their admin why do they reject your mail. Probably they need you provide PTR record or SPF record. No matter what they need, i want to say that the issue isn't at your side.
hope can help you

While it could be some convoluted way of enforcing anti-spam, the most obvious reason would be due to an invalid recipient, or the recipient is unauthorized to accept mail, such as a scenario where they are over their quota or something.
