[Mailman-Users] Domain problem in post action on admindb forms for multi-domain mailman

[Martin Brampton]

I'm running Mailman 2.1.13 from the Debian Squeeze repositories (on 
Debian Squeeze) to provide mailing lists across several domains.  The 
domains that are not the primary mailing list domain have 301 redirects 
of URLs such as .../listinfo/xxxx or .../admin/xxxx to the primary domain.

In most cases this works, because the action in the form is relative, 
and the page is showing on the primary domain on account of the 
redirects.  When the form is submitted, the request therefore goes to 
the primary mailman domain.  (Other domains are typically on different 
servers from Mailman, and do not have Mailman installed at all).

However, the .../admindb/xxxx pages seem to have a specific domain in 
the action attribute of the form, and it is the actual domain of the 
mailing list, not the primary domain.  Although the redirect sends the 
post to the mailman server, redirecting a post request loses all the 
data, so nothing happens.

Is there something wrong with my setup?  Is there a way to resolve this 
problem?
