[Mailman-Users] Puzzle Regarding Sender Header

I just moved a Mailman setup from one server to another. This is
Mailman 2.1.12, with one modification, described in this message:
Basically, I change the Sender header in SMTPDirect.py so it comes
from the -admin address rather than the -bounce address:
# msg['Sender'] = envsender
msg['Sender'] = mlist.getListAddress('admin')
The new server has two network interfaces. Each interface has its own
IP. The second interface has a single IP, call it 127.0.0.2, with two
hostnames mapped to it:
intranet.foo.org. A 127.0.0.2
lists.foo.org A 127.0.0.2
The reverse DNS mapping for 127.0.0.2 points to intranet.foo.org.
I've set the host_name for all the lists to be 'lists.foo.org'. I
also set DEFAULT_EMAIL_HOST and DEFAULT_URL_HOST to 'lists.foo.org'.
I also ran fix_url for all the lists.
Everything is working fine, except for one problem: the Sender: header
in messages is 'listname-admin at intranet.foo.org' rather than the
desired 'listname-admin at lists.foo.org'.
I added this to mm_cfg.py, but it didn't help:
DEFAULT_EMAIL_HOST = 'lists.foo.org'
DEFAULT_URL_HOST = 'lists.foo.org'
The weird thing is that if I use withlist, it tells me the list
address is 'lists.foo.org' (I've obfuscated the hostname consistent
with the rest of this message):
$ withlist -l test
Loading list test (locked)
The variable `m' is the test MailList instance
'test-admin at lists.foo.org'
'test at lists.foo.org'
I undid my patch as a sanity check, but it does what I'd expect: the
Sender: header is now "test-bounces at intranet.foo.org" rather than
"test-admin at intranet.foo.org", but not "test-bounces at lists.foo.org".
Any ideas? Thanks.
