Lists: domain name host name?

Question

In the 'General' tab of the Mail service window in Server Admin I've got the following:
Domain name: subdomain.mydomain.com
Host name: mail.mydomain.com
So my e-mail addresses like [email protected] work fine. But what's weird is that when I'm creating mailing lists , the internal users get added to it like this: [email protected]!? Why is it that? Why don't they get added with [email protected]?
Because the problem is if they send something to the list, it gets denied because the mailing list considers them non-members!
Any ideas what the problem could be and how to correct that?
Thanks.

All,
From the Mail Service PDF Manual;
"Adding a Subscriber to an Existing List
This is the same procedure as adding a user to a newly created list.
To add a subscriber to an existing list:
1 In Server Admin, select Mail in the Computer & Services list.
2 Click Settings.
3 Select the Lists tab.
4 Select the List to which you want to add a subscriber.
5 Click the Add button under the Members pane.
6 Enter the recipient’s email address.
The email address must match the return address of the recipient to post messages
without administrator approval.
If a user was added via the “Users and Groups” button, the email address in the list will
be in the form of “[email protected]”. If necessary, change the email address in
the mailing lists panel of Server Admin to match the return address used by the client.
7 Assign the subscriber privileges.
8 Click OK."
In other words, click in the user's email field and edit the address to suit - by default Mailman treats the list as belonging to the machine's host name, not to the email domain/sub-domain, which is the most logical since you could have multiple domains/sub-domains configured.
