This looks like a normal message delivery from the 'parents' list to
person1 at pacbell.net

This message is from the site list, not the 'parents' list. Such
messages are normally notices to list owners/moderators. If
person2 at sbcglobal.net is not an owner/moderator of some list and is
only a member of the 'parents' list, then I don't offhand know what's

Do you have access to Mailman's logs? If so, what's in the smtp and
smtp-failure logs? See the FAQ at <http://wiki.list.org/x/sYA9> for a
discussion of why our ability to help is limited in this situation,
and for info on the location of files in a cPanel installation.

If you think the problem is the 'myhost' in
mailman-bounces at myhost.DOMAIN.com as opposed to the absence of
'myhost' in parents-bounces at DOMIAN.com, you may be able to fix that if
you have command line access to Mailman. You would need to run
'fix_url' on the 'mailman' list. In a normal, non-cPanel installation,
I think all that would be required is

cd path/to/mailman
bin/withlist -l -r fix_url mailman

Even simpler, if you can access the web admin interface for the
'mailman' list, you will probably find that host_name near the bottom
of the General Options page is set to myhost.DOMAIN.com and you can
simply change that to DOMAIN.com.

You can give them the above information, but as Brad already said, they
already aren't supporting you, at least as far as Mailman is concerned.
