As I understand it, fetchmail will look at the To:, Received, CC: and
Bcc: headers to try and determine a multidrop recipient even in the
absence of a header such as you describe. How well this works depends
on your own setup. For example, it worked perfectly for me without any
extra headers for a long time when I had to forward three specific
users at domain.blah to their own usernames while forwarding all other
addresses at domain.blah to another user.
