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:

VIRTUSER_DOMAIN(`example.com')dnl

...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.
