You have something like helo_try_verify_hosts and

It seems the host HELOed with reverse.154.51.184.66.static.ldmi.com,
which is its PTR record:

nslookup 66.184.51.154
Server:         172.20.0.254
Address:        172.20.0.254#53

Non-authoritative answer:
154.51.184.66.in-addr.arpa      name = reverse.154.51.184.66.static.ldmi.com.


However, reverse.154.51.184.66.static.ldmi.com yields no results.

nslookup reverse.154.51.184.66.static.ldmi.com
Server:         172.20.0.254
Address:        172.20.0.254#53

** server can't find reverse.154.51.184.66.static.ldmi.com.eriador.org:
NXDOMAIN

So exim is just logging this
