You will probably get more info at message queue on Exchange server.
I vote for problems on the other side.

I go to email properties to check the send out email header but is bland empty. should I look the incoming email or outgoing email header?

None of them ever left your server, that why you have smtp header empty. Incoming mail it is just notification from your server. If it had some info about why the original message is delayed, you would see that in the message body. You will need to check the message queue for the reason.

Yes, they are not sent yet.
It looks like DNS server you are using for delivery have some problems.
I would check your DNS servers first. If you are using forwarders you can try to change them to some others - like google's 8.8.8.8 and 8.8.4.4.

to analyse  message headers you need the email from the recipient, i was assuming that you had a yahoo account you were using to test.
Thats the only way you get the stop off points in the journey
