Unless you're using percenthack, then it is an unknown user.
If you need to specificly mark these, then you could try
something like this at the top of your directors:

  reject_percenthack_relay:
    driver = smartuser
    condition = "${if match{$local_part}{.*%.*}{yes}}"
    new_address = :fail: rejected percent-hack relay attempt


setting "receiver_verify = true" should reject these at transaction
time, even if you deliver "any local part"@domain.
