controller_admin_mailing_preview
This controller shows a preview of what a resource that is being mailed would look like, in a popup window.
The required id argument identifies the page being mailed. The current user
must be allowed to use mod_mailinglist and view that page. The controller
renders the category-aware mailing_page.tpl with:
id: the page being previewed;list_id: the namedmailinglist_testresource;email_from: the sender address configured for that test list.
Use {% url admin_mailing_preview id=id %} to construct the preview URL.
