There's a big long discussion of this in cf/README, but reasonable people have
been known to find sendmail documentation non-informative. :-)
It might be the case that using statements of the form:
...in your .mc file may help exclude them from canonification.
It may also be the case that what you want to do is going to be better handled
by two SMTP servers, one as an external gateway, using and exposed to DNS and
your wildcard MX records, and one internal mailserver which handles local
delivery, masquerading, a mailertable distributing mail to any other local SMTP
destinations (think mailserver/listservers running on other machines), and even
use FEATURE nocanonify if you want to/have to disregard DNS entirely.
Put a spamfilter/virusfilter on your external relay, which will then serve as
your SMART_HOST for the internal mailserver.
