This will almost certainly be due to reverse DNS problems, or use of ident.

1) Check your Exim server can resolve reverse DNS - 'host
192.168.1.12' might tell you this. The delay may be due to resolver
timeouts.

2) Unless you have a specific use for it, turn off ident checking with
'rfc_1413_timeout = 0s' in your Exim config. This will stop Exim
trying to do an ident query to the client, which may be dropping ident
traffic at a firewall.
