Fetchmail can set the SMTP "RCPT" header appropriately. Just configure it
for multidrop mode: there's advice on this in the fetchmail documentation
and FAQ, including a few examples.

It supports a number of ways to find the header information:

    a) Special headers, like the Envelope-To: that exim adds.
    b) The *env command (I think only demon provide this though)
    c) Parsing the received headers, if they include the necessary
        information.
    d) The To: or Cc: headers (not recommended).


That, together with an alias file, would seem to be a much neater way of
doing this than using any filtering at all (although you may in future want
filtering for various other reasons, of course).
