Email Headers X-Apparently

I am having trouble with mail being sent to my Yahoo email account. They sometimes take hours to arrive after sending. Trying to find out if its Yahoo or the sender thats the problem and why. I've removed some basic errors to make things clearer:

Problems I've noticed:

1) Its coming through as X-Apparently.
2) There is a (may be forged) in one of the headers.
3) The timestamp their end is +0100: Fri, 30 Jun 2006 10:46:14 +0100. Locally it is: Fri, 30 Jun 2006 09:46:08 +0000

Any ideas?

Thanks,

Lee.
