Hm... (if I remember right) the transport filter calls an external
program
... Uhh ... That´s not very nice ... and expensive! As you said!
If Exim could handle this... That would be a lot better!

Hm... That might be an easy sollution, but such a intranet might be a
net
with all mixtures of machines with maybe windows on it ...
And they don´t have a local mailqs ... Maybe they write their mail with
Netscape ... And the receipents machine is off (home already ;-) ..
So the mail can not be delivered before Netscape is started again ...
But it may be an very important mail! The receipent should have next
morning!
You see the problem? ... I think also the local mail should be handled
by the server/gateway machine ... If you have 2 of them, 1 server and 1
gateway
each running exim this might be no problem.
