[Mailman-Users] Using a hostname other than the server's primary name...

Brief Overview:
The box that currently hosts our Mailman lists has several different
hostnames, some of which (including its primary) are only resolvable
from inside our firewall.  While Mailman is configured to prefer a
non-primary hostname, generated emails include the primary hostname in
some of their headers (including "Sender", "Return-path", and
"Reply-to"), resulting in the use of addresses which are undeliverable
from outside our local network.

Is it possible to override this behavior?

Detailed Information:
The primary hostname of the server which hosts our Mailman lists is
"baruch.letnet.net".  For a number of reasons, this hostname is not
resolvable from outside our firewall.

This server has additional hostnames ("www.letu.edu" and
"lists.letu.edu") which are resolvable and accessible from outside our

Lists are configured with host_name (Host name this list prefers for
email) set to "lists.letu.edu".

An e-mail sent through the list, however, gets headers which include the

> From: "Roedel, Mark" <MarkRoedel at letu.edu>
> X-BeenThere: deck3 at lists.letu.edu
> X-Mailman-Version: 2.1.5c2
> Reply-To: Deck 3 alumni and friends <deck3 at baruch.letnet.net>
> List-Id: Deck 3 alumni and friends <deck3.lists.letu.edu>
> List-Unsubscribe: <http://www.letu.edu/mail/lists/listinfo/deck3>,
> 	<mailto:deck3-request at lists.letu.edu?subject=unsubscribe>
> List-Archive: <http://www.letu.edu/mail/lists/private/deck3>
> List-Post: <mailto:deck3 at lists.letu.edu>
> List-Help: <mailto:deck3-request at lists.letu.edu?subject=help>
> List-Subscribe: <http://www.letu.edu/mail/lists/listinfo/deck3>,
> 	<mailto:deck3-request at lists.letu.edu?subject=subscribe>
> Sender: deck3-bounces at baruch.letnet.net
> Errors-To: deck3-bounces at baruch.letnet.net
> Return-Path: deck3-bounces at baruch.letnet.net

Any way (using the SMTPDirect handler, in case that matters) to ensure
that all headers that refer to the list address use the correct
hostname?  Reply-To is the most visible problem for list subscribers,
and although I can of course override that by providing an explicit
reply-to address, it seems like it'd also be to our benefit to have
Sender/Errors-To/Return-Path contain reachable addresses as well...
