LPS-32885 We don't want to mix English with other languages. So we need a different key for each "via". Or else, you could get a Chinese sentence with English mixed in. Also, see portal.properties:

    #    # Set the list of announcement types. The display text of each of the    # announcement types is set in content/Language.properties.    #    announcements.entry.types=general,news,testThis ensures that even the delivery types are translated.
