No...local_part applies to the recipient.
You need the senders router precondition (see the discussion of the order
in which preconditions are processed), or, particularly if VERP is involved,
conditions related to one or more of these--perhaps others--expansion
variables:
$sender_address
$sender_address_domain
$sender_address_local_part
or perhaps
$sender_host_address (if the list software is on a different machine)
Things may be easier if the list folks only insist that you trap messages
bound for subscribers or would-be subscribers, not those bound for list
administrators. Or if the list software has its own domain, such as
lists.example.com (but then you're trusting the list's configuration).
And lots easier if the list software is on a machine that need not send
other mail (watching out for mail sent by cron-related stuff if that goes
off-machine).
