2. 550 5.7.1 Unable to relay & 550 5.1.1 RESOLVER.ADR.ExRecipNotF
No Spelling mistakes, ive found some good information regarding the 5.1.1 issue. I believe it happened since i deleted the mailbox and created it several times. It works normally through OWA. The issue is related to the smtp address saved in the AD. Regarding the other issue, i guess we were blacklisted somewhere...

4. SMTP server responded with "550 5.7.1 Unable to relay
We currently have a Windows SBS 2003 server. Exchange has been installed and working correctly on the server. We had a domain miltonconstruction.com. We are forwarding all of our mail over to a new domain name miltonhayes.com. I added the domain as the default domain in the recipient policy. The mail goes out with the correct domain name on the email, however if you try to send or reply to the new domain (miltonhayes.com) it gives the following error message: This is an SMTP protocol log for virtual server ID 1, connection #6. The client at "64.233.178.249" sent a "rcpt" command, and the SMTP server responded with "550 5.7.1 Unable to relay for XXXX@XXXXX.COM ". The full command sent was "rcpt TO:< XXXX@XXXXX.COM >". This will probably cause the connection to fail. I called the web hosting company and they said that the mx record for both of the domains is pointed to our IP. Does anybody know what might be causing this issue and how to resolve? Thanks

For the past week, we've been getting these NDR's. It happens from multiple domains, but randomly. Sending an email will fail one time, then work when it is resent. You do not have permission to send to this recipient. For assistance, contact your system administrator. <ourdomain.com #5.7.1 smtp;550 5.7.1 Unable to relay for XXXX@XXXXX.COM > Nothing has changed on our end. I'm not sure what is going on. Can anyone help shed some light? Thanks!
