Hi all,
This problem has been fixed, thanks to the following people, especially
Rudy Willis who gave me the solution;
Alvaro Jose Fernandez Lago <alago@galeno.unicies.cesga.es>
Brian Exelbierd <bcexelbi@controller.osc.state.nc.us>
Todd Herr <herrt@hankhill.iisd.sra.com>
Larry Chin <larry@sprint.ca>
Chad Price <cprice@molbio.unmc.edu>
Rudy Willis <rudy@pbis.com>
David B. Harrington <dharringt@deq.state.va.us>
Here is Rudy's response;

Dale,
Have you compiled with NAMED_BIND=0 (see src/conf.h),
as per the README in src?
NAMED_BIND If non-zero, include DNS (name daemon) support, including
MX support. The specs say you must use this if you run
SMTP. You don't have to be running a name server daemon
on your machine to need this -- any use of the DNS resolver,
including remote access to another machine, requires this
option. Defined by default in conf.h. Define it to zero
ONLY on machines that do not use DNS in any way.

This is the fix/hack/kludge..
Most others suggested I was the SMART_HOST (DS) feature of sendmail - I
mustn't have made it clear in my original e-mail that I was already
using this yet sendmail was still attempting name resolution on the
recipient's domain.
I'm not yet sure if anything will "break" with no DNS - even if some
features don't work, I doubt I would use them anyway. It's a very
simple configuration. Other suggestions did fix my problem in some
way, however most disabled any prospect of local delivery.
My original e-mail is below.
Thanks again, Dale
