Reading the URL

  http://postmaster.info.aol.com/errors/554rtrch.html

givem in the respomse suggests that the greyhoundhomer.org.uk
domain (or the IP address of its mail-server) may have been the
source of mail which has been flagged as SPAM by an aol users.
As a result, aol.com refuses to talk to that IP address.

In turn, greyhoundhomer.org.uk's mail-server doesn't talk to
mail-servers' that won't talk to it!

Classic domestic Catch-22.
Thinks A: "I won't talk to you until you talk to me."
Thinks B: "I won't talk to you until you apologise for
  what you said last time we spoke."
Thinks A: "Why won't [s]he talk to me?"

(Of course, this may not be the true explanation, but it is
seriously compatible with the information).

If that is the case, the solution would seem to be that
greyhoundhomer.org.uk should take steps to get back into aol's
good books (as suggested in the URL).

Best wishes,
Ted.
