Email Headers

I am having issues with email.  One of my clients emails don't arrive until a full day, sometimes more, later.  
My ISP claims they are not to blame. What do you see on this headers? Who can i point the finger at?

To clarify the above. All we really know from that header is the info in my first post above.

So the delay was in the connection between those two hosts.

We don't know which host caused the delay, but given that received the message in a timely manner, it was clearly functional at the time. Given that it's your clients server, your client should be able to refer to the logs on that server and see what was occurring to that message while the server was attempting to transmit it to

but didn't receive it from until Wed, 16 Mar 2011 09:17:03 -0700

so the one delaying it is, correct? Which is my client's server.  My ISP is correct then, it is nothing wrong with them?
Well, it's going to be one of those.

You would need to refer to the logs on the server for more information.
