I'm having trouble using UK-Sendmail-2.1.  I have domain tables which
correctly deliver fully qualified domain addresses given any uk academic
site.

For the channel tables all I largely want to do is pass and domain name
beginning with uk. straight onto unix-niftp.  To do this I have a
file called 'local-janet.chn' which is configured as a janet
channel file in which I have the line:

uk.%s	uk.%s

There is another file called janet.chn which holds all the other relaying
information.

When run in test mode I can see ruleset 16 gradually stripping the address
down until only 'uk' is left.  I then get the 'Domain Unknown' error.

*What am I doing wrong?*

Here is the sendmail header:
derek.cs.keele.ac.uk Sendmail 4.12/UK-2.1 ready at Thu, 2 Feb 89 20:58:05 GMT

And here is Ruleset 16:
