You may be misreading the logs. What evidence do you have that
in fact there is a separate delivery for each recipient. LOGS!
That said, if the pipe transport is reached via "mailbox_transport",
then indeed you get one delivery per recipient, because the recipient
concurrency for the "local" transport (correctly) defaults to 1,
and "mailbox_transport" is local(8) delivery agent feature, in
which some mail is punted to another transport for delivery after
alias expansion.
