[comp.mail.sendmail] Bug or feature?

haynes@ucscc.UCSC.EDU (99700000) (03/16/91)

We have a bunch of uucp clients, some of which are registered in the
US domain.  Here's part of my sendmail.cf

# Class for uucp clients
CVmumble
...
# Rewrite US domain addresses for uucp clients
R$*<@$=V.santa-cruz.ca.us>	$#uucp$@$2$:$1

The problem is that occasionally we receive mail addressed to
   USER@MUMBLE.SANTA-CRUZ.CA.US

and this gets bounced by uucp because MUMBLE is not the same as mumble
in uucp addresses.

I could of course write a whole bunch of rules, one for each uucp client,
like
R$*<@mumble.santa-cruz.ca.us>$*  $#uucp$@mumble$:$1

and this would turn the upper case hostname into lower case, but I'd rather not.
I can't decide whether uucp is wrong in being case-sensitive.  Is there
some way in sendmail to turn a hostname into all lower case?
