Probably won't work for multiple recipients. From the manual,
Chapter 11 - String Expansions:

$local_part
When an address is being routed, or delivered on its own, this
variable contains the local part. When a number of addresses are
being delivered together (for example, multiple RCPT commands in
an SMTP session), $local_part is not set.
