exim 4 is much easier to understand.
exim 3 has two separate sections that handle "outgoing" mail. One of
them, directors, is for outgoing mail that is delivered locally. The
other, routers, is for outgoing mail that isn't being delivered
locally. What you want to do is copy the spamcheck_director into the
top of the routers section.
By changing the domainlist router to use the spamcheck transport
here's what happens :
1) new message arrives.
2) route it -- it isn't for a "local domain", check the routers list
3) "domainlist" router accepts responsiblity for it
4) deliver it -- the router says to use the "spamcheck" transport
5) feed it to the spamcheck transport, we're all done here
6) new message arrives (this "new" message is the output from spamc,
it's really the same message but exim doesn't know that)
7) go to #2
ad inifinitum
The trick to changing step #7 is to set $received_protocol during the
spamcheck transport and then bypassing the spamcheck_router (which you
will create by moving the spamcheck_director).

No.
It is important, when configuring exim, to understand how exim handles
addresses and messages (routers, directors, transports and the
interactions between them).
