You probably don't want limited_masquerade...read on...

Quoting /usr/share/sendmail-cf/README (from sendmail-cf-8.11.6-3):
limited_masquerade
Normally, any hosts listed in class {w} are masqueraded. If this
feature is given, only the hosts listed in class {M} (see below:
MASQUERADE_DOMAIN) are masqueraded. This is useful if you have
several domains with disjoint namespaces hosted on the same
machine.
...
Normally the only addresses that are masqueraded are those that
come from this host (that is, are either unqualified or in class
{w}, the list of local domain names). You can augment this list,
which is realized by class {M} using
MASQUERADE_DOMAIN(`otherhost.domain')
The effect of this is that although mail to [EMAIL PROTECTED]
will not be delivered locally, any mail including any
[EMAIL PROTECTED] will, when relayed, be rewritten to have the
MASQUERADE_AS address. This can be a space-separated list of
names.
If these names are in a file, you can use
MASQUERADE_DOMAIN_FILE(`filename')
to read the list of names from the indicated file (i.e., to add
elements to class {M}).

I don't think DNS has any impact on this.

Again from the README:
If your host is known by several different names, you need to
augment class {w}. This is a list of names by which your host is
known, and anything sent to an address using a host name in this
list will be treated as local mail. You can do this in two ways:
either create the file /etc/mail/local-host-names containing a list
of your aliases (one per line), and use ``FEATURE(`use_cw_file')''
in the .mc file, or add ``LOCAL_DOMAIN(`alias.host.name')''. Be
sure you use the fully-qualified name of the host, rather than a
short name.
This is pertinent to class {w}, the "list of names by which your host
is known," not class {M}, the list of domains that should be
masqueraded. When you enabled the limited_masquerade feature, you
stated that you wanted ONLY the class {M} names to be masqueraded, and
not the class {w} ones. So you either need to add entries with
MASQUERADE_DOMAIN or MASQUERADE_DOMAIN_FILE, or remove the
limited_masquerade feature to allow your host's other names to be
masqueraded as designed.

That's the same as MASQUERADE_AS(domainname.com) in your .mc file.

That's new to me...I don't think I understood the suggestion.

I hope the information above will cover it.
In the mean time, when you modify the sendmail.cf file or any of the
files referenced by it (except aliases -- I don't think there are any
others that automatically get re-read), remember to restart sendmail so
it will use the new configuration. (I've been stumped a number of
times when my changes didn't work, and then realized that I hadn't
actually caused them to be used!)
Truly,
Jonathan
