|Think we're talking at cross purposes. Below is a script listing showing
|the creation of 2 configs - test1 and test2. They are identical except
|for the order of the domain declarations in the config file. You'll
|see that there are indeed differences between the resultant sendmail
|configuration files but these diffences do not affect the order of
|domain resolution. In both, "computervision" still resolves to
|computervision.co.uk

I see your point. I suggest you do as the manual tells you, and use
the sequence

(assume your config is called $config )

$ cd $SENDMAIL/$config && make check $config install

This will abort if any potential conflicts are detected. You can then
delete the entry you dislike.

We in fact do something more - a makefile generates new NRS derived
input decks by editing out names we know to be a problem, like 'uk.ac.co',
'uk.ac.mrc' etc (we have a uk.ac.gla.mrc)

I enclose the relevant script, which Jim thought too obvious to put into
the package:-


mk.sendmail.db

# Bring sendmail domain databases up-to-date
