Did you add the new domain to the Accepted Domains list in Exchange (see Organisation config)?

Not sure what you are referring to by new domain. my email is waynel@ablehealthcare.com. In exchange management, I added and alias of ableweb@ablehealthcare.com to my smtp addresses to any mail sent to that alias would come to my real email account. I have several others that work fine internally and externally. The one I just added works internally but senders from the outside get rejection errors above.

a few quick questions,

1. are you using an Exchange edge transport server
2. or a Third party mail filter appliance / service - is this alias created there ?
3. what is the system policy for email addresses in your org ?

5.7.1      A very common Exchange 2010 NDR, the cause is a permissions problem.  For some reason the sender is not allowed to email this account.
       Perhaps an anonymous user is trying to send mail to a distribution list.
       Alternatively, a user may have a manually created email address that does not match a System Policy.
       Check SMTP Virtual Server Access Tab.  Try checking this box: Allow computers which successfully authenticate to relay.
       Check the outgoing SMTP logs.
       Check: Mailbox – <Mailboxname> – Properties – Mail Flow Settings – Message delivery restrictions.
       Try disabling Windows-Integrated-Security.  Instead allow only standard authorization on the SMTP receiver on the Exchange 2010 server.
       Check Attachment filtering on the Edge server.
