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?).
