A coherent explanation of the problem? :-)
I'm afraid your explanation of the problem didn't make much sense to me, so
for now I'm going to make some guesses: I'm guessing that there's only one
Exim server in this situation, and it's probably not on 192.168.0.7;
192.168.0.7 is some client trying to submit mail to exim. And it sounds like
you don't want to reject due to lack of reverse DNS for local clients
(192.168.0.0/24).
If all that is correct, then the problem is this part of your config:

It looks like you're applying greylisting to *all* clients who lack reverse DNS.
As for how to fix that, I can't tell you for sure, because I don't know your
requirements. It might be as simple as adding a "hosts" condition just before
you set acl_m_greylistreasons (e.g. hosts = !192.168.0.0/24). Or, if this
Exim server ONLY accepts connections from clients that you trust anyway (i.e.
it doesn't handle mail directly arriving from the Big Bad Internet), maybe you
should just strip out the greylisting stuff entirely.
On the other hand, if I've guessed incorrectly then perhaps you could try
explaining your problem again?
