Hmm, the domains.txt I got with the ``make'' had 'em in, so I figured 
they were meant to be :-I

Ok, done - thanks.  I'll keep an eye on things.

It also looks like my FEATURE(`nocanonify') dodges all these rules 
anyway, so I've lost that.  Mike Burgett pointed me at an interesting 
site:

  http://www.informatik.uni-kiel.de/%7Eca/email/check.html

and suggests 

HACK(`use_ip', `/etc/LocalIP')dnl
HACK(`use_relayto', `/etc/RelayTo')dnl
HACK(`check_mail2', `hash /etc/Banned.db')dnl
HACK(`check_relay')dnl
HACK(`check_rcpt4')dnl

as a cleaner solution.  I'm only half-quoting, so forgive me if I'm 
missing something relevent.  I'm really gonna have to figure out how 
all this works at some point (Yep, O'Reilly & Assoc. is the best read 
I suspect, but does it cover all the m4 stuff ?).
