mailscanner shutdown

[Ulysees]

is there any cleaner way of causing mailscanner to shutdown ?
maybe it's more of a sendmail flaw but leaving around half finished xf and
df files in the the queues causes me a fair bit of annoyance.
they way i figure it should it not be possible on shutdown to refuse new
connections and wait x period for existing messaged to be delivered and then
after that kill them but remove the dead bits from the queue ?
