see lots of spam email rejected thanks to this.
Now that I'm here, I would like to add:
I think that what confused me is that Postfix said:
NOQUEUE: reject: RCPT from unknown[188.39.73.166]: 450 4.7.25 Client host

Do you think that the error "Client host rejected: cannot find your
hostname" is because the IP->hostname and hostname->IP lookups are not
matching?
I think that it should have written "Client host reje

That is sufficient to satisfy reject_unknown_reverse_client_hostname.
But you have also configured reject_unknown_client_hostname. That
requires that mailcluster.zen.co.uk
I think the answer is in your question ?
Prefix 188. vs prefix 166. ?
Plus neither 188. or 166. are present in a forward lookup for
mailcluster.zen.co.uk ?
That's some truly messed up DNS you've got there ?
