Thanks to all for the thorough replies. It appears
that the solution actually lies in disabling ident.
In Exim, this is achieved by setting the timeout to 0.
#rfc1413_query_timeout = 30s
rfc1413_query_timeout = 0s
I may go back and turn it on again with a smaller
timeout (suggestions as to how long is reasonable?).
