I've discovered that some mail between two of my clients (on separate hosts)

finding what this rule is about and what to do about it.
Your reverse DNS lookup for the hostname resolves to a string containing
'in-addr.arpa'. This can be corrected by setting your reverse DNS zone to
a real hostname for the IP. If you are not in control of the DSN you may
have to talk to your upstream provider.
If you are only doing this internally, and never send external mail from
that host, you can just add a whteilst entry for that hostname.
