Yes, as detailed in the docs on the amavisd-new website,
Exim processes the
message, hands off to amavisd-new on the local machine,
which the
re-injects the message back into Exim to be sent on to its
destination.

You therefore end up with an initial header being added by
Exim which looks
a bit like this:

---- snip ----

Received: from [190.67.164.205] (helo=estacion03)	by
 my-amavis-server.local with smtp (Exim
4.63)	(envelope-from
 <BrittanybostonCoffmaneclipse.org>)	id
1JH0Cw-0007yR-1j	for
 richardxxxxx.co.uk; Mon, 21 Jan 2008 17:13:14 +0000

---- snip ----


I did consider trying to read the IP from the headers but
decided that it
was probably easier to insert a custom header and get the
info from there -
being that the headers are parsed out by the existing code.

Excellent!  This is even better than my solution.  Is this
going to be
included into the 2.6.0 release?  If so then I'll wait for
the stable
release and upgrade then.


Many thanks for this!
