I'm not sure if I understand correctly, but you shouldn't need to
modify templates regarding email confirmation. You may want to modify
the subscribeack.txt template to be more appropriate for an
announcement list, but that's a different issue. See

Your aliases MUST work and you MUST be able to receive mail at some
domain and pipe it appropriately to Mailman. This domain would be your
DEFAULT_EMAIL_HOST and would be the host_name attribute for each list.
I suppose it would be possible to run an announcement list that
couldn't receive email, but bounce processing wouldn't work, posting
would be awkward and subscribing/unsubscribing/option-setting/etc.
couldn't be done by email.

So bottom line is you have to set up your MX records and incoming MTA
to be able to receive and deliver to Mailman.

You probably also want your MTA to listen on 'localhost' for outgoing
