Here are the options you need to look at. These example is taken from a
default Exim config file like this one:
http://www.exim-new-users.co.uk/content/view/133/39/
The RFC mentioned can be found here:
http://www.ietf.org/rfc/rfc1413.txt
# The settings below, which are actually the same as the defaults in the
# code, cause Exim to make RFC 1413 (ident) callbacks for all incoming SMTP
# calls. You can limit the hosts to which these calls are made, and/or
change
# the timeout that is used. If you set the timeout to zero, all RFC 1413
calls
# are disabled. RFC 1413 calls are cheap and can provide useful information
# for tracing problem messages, but some hosts and firewalls have problems
# with them. This can result in a timeout instead of an immediate refused
# connection, leading to delays on starting up an SMTP session.
rfc1413_hosts = *
rfc1413_query_timeout = 30s
