The scripts/owner script which receives mail addressed to -owner sets

   envsender=Utils.get_site_email(extra='bounces')

(this is in Mailman/Utils.py). This in turn gets the domain part of the
address in a complex way (see Utils.get_domain()), but in this case,
it boils down to

  - get DEFAULT_URL_HOST
  - look up the corresponding email host in mm_cfg.VIRTUAL_HOSTS
    (the dictionary built by add_virtualhost())

So it looks like you probably have more that one add_virtualhost()
entry with the same url_host argument (either DEFAULT_URL_HOST or its
literal value.

This doesn't work. VIRTUAL_HOSTS is a Python dictionary (hash table)
with key = the first add_virtualhost() argument and value = the second.

So, if you have something equivalent to

add_virtualhost('www.example.com', 'example.com')
add_virtualhost('www.example.com', 'example.net')

the second entry replaces the first.

All url_hosts and all email hosts in

add_virtualhost(url_host, email_host)

lines need to be unique for it to work as intended.
