Exim relaying outgoing mail?

["Marc Sherman" <msherman@projectile.dyndns.org>]

I've read through the Exim man page and the config
file, but I couldn't figure out how to set up exim
quite how I need it; can anyone offer any advice?

I don't want to touch incomming mail -- it's working
correctly.  However, for outgoing mail, I'd like my
SMTP server to relay all outgoing mail through my
ISPs SMTP server, instead of sending it directly
to the destination SMTP server.  This is because
my machine is using a dynamic DNS name, which means
that any site which does a reverse lookup on the DNS
will block my mail because it will seem to be spoofing
it's IP/DNS.

I suspect that what I have to do is change the transport
section:

remote_smtp:
    driver = smtp

to add a setting saying what machine to relay through,
but I'm not certain.  Does anyone know?
