The ISP dns servers will not resolve the krikkit.local domain for which you
are forwarding the email too (a guess, but propably a good one).
What does the Routers section of the exim.conf file look like?
Instead of passing the forward to a dnslookup router/transport, why not
just pass the mailing host information directly to the transport?

Did anything 'change' recently? (updates, new software installs, add new
servers/workstions to the network, change of hardware, etc.)

Then I guess I am at a loss without some debugging information.
Is the server heavily loaded when the errors occur?
Can you recreate the problem at all?
etc...
