Incoming mail only rejected by this user on Exchange 2013, why?

This is using MS Exchange 2013 server. Recently, a user always can't receive external incoming mails from a email domain, while all other users without problem. In EAC > delivery report, this is the error message:


   Delivery report for
   11/5/2015 from mailserver.def.local
   This message was rejected by recipient's email system. Please check the email address.
   (LRT=); (LED=554 5.1.0 Sender denied) (FQDN=);(IP=)

  I ever checked the usera's junkmailconfiguration, and found that the above incoming email address wasn't listed.

Thanks in advance.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That usually is a blocked sender at the user level. If everyone else can receive email from that domain then it is definitely something user specific.
I would suggest you check through OWA, rather than Outlook to begin with.

I typed get-mailboxjunkemailconfiguration on the affected user mailbox, and found a lot sender email addresses listed in blocked sender. I didn't found the affected sender email address. However, I found it in the Outlook - blocked senders. I have told the user help to monitor and is working fine so far.

Thanks for Simon to point to correct direction precisely and with short but sharp decision.
