Is this on Exim 4.61 or greater, yet? (Full version numbers are good,
not just assuming we all know which particular release of Exim is in
which of N branches that are currently being maintained by an OS
distributor).

If you're not yet on Exim 4.61, then this is the default value of
rfc1413_query_timeout; Exim does ident lookups by default. The new
default value is 5 seconds; if you will never send abuse reports or
expect people to trace a complaint, then you can also just disable ident
lookups entirely.

I personally think the new Exim defaults are reasonable for most cases
and you should leave it turned on; if it's failing then someone's being
an idiot with their packet filtering somewhere and preventing the TCP
RST "port is not listening" rejection notice from being delivered. If a
port is closed and can be seen to be closed, Exim does the obvious &
right thing and just continues.

(If it's not rfc1413, then check for working DNS for the connecting IP)
