[Mailman-Users] messages to listname-bounces lost

[K. Clair]

Hello,

I'm trying to move our current nfs-based mailman setup (where we have
separate mail and web servers and mailman files on nfs) to a dedicated
mailman machine (where our mail and web servers will forward and
proxy, respectively, mailman requests to the mailman machine).

For mail, I have set up virtual domain aliases on our mail servers to
forward mail to lists at virtual domains to the local list aliases on
the mailman machine, for example:
listname at domain.com -> listname at mailman.server.com
listname-bounces at domain.com -> listname-bounces at mailman.server.com
etc...

When I try to submit a subscribe request via the web interface (which
happens on the mailman server), I see mail sent to the
listname-bounces address.  Since the listname is set up to send mail
from its virtual domain, the mail first goes to
listname-bounces at domain.com.  This of course forwards back to
listname-bounces at mailman.server.com.
It is at this point that it gets lost - it gets sent to the mailman
command, and nothing happens.  Nothing in the error log or any of the
logs.
The mail logs look like this:

Oct  3 17:08:54 rm-101-11 postfix/smtp[12624]: EFC9211700FC:
to=<ladies-bounces at domain.com>, relay=mail.server.com[IP]:25,
delay=0.15, delays=0.04/0/0.09/0.01, dsn=2.0.0, status=sent (250 Ok:
queued as DF530288DC)

Oct  3 17:09:38 rm-101-11 postfix/local[12633]: 5D62711700F2:
to=<ladies-bounces at mailman.server.com>, relay=local, delay=0.44,
delays=0.01/0.02/0/0.41, dsn=2.0.0, status=sent (delivered to command:
/usr/local/mailman/mail/mailman bounces ladies)

Is this a problem that is being caused by the forwarding setup?

Thanks,
Kristina
