[Exim] Safe Kill

Hi

How do I tell exim to finish off it's current connections?

For e.g. I have constantly about 10 - 30 mailtransfers happening
simultaneously.
I want exim to refuse new transports/connections and finish off with what it
is busy with before I kill the exim pid and reload it.

How??
