Have you updated your exim configuration to send as a valid DNS
resolvable host name, as well as set up DNS for that host name?  I think
that is your problem, here.

I have no problems sending email from quite a few hosts, using a similar
path as you describe, but I have configured the local MTA on each box to
send as valid DNS resolvable names:

mshuler@kokopelli:~$ sudo grep -r kokopelli /etc/exim4/

mshuler@kokopelli:~$ host kokopelli.pbandjelly.org
kokopelli.pbandjelly.org is an alias for kokopelli.homeunix.org.
kokopelli.homeunix.org has address

The above is my laptop.  Hope that helps!

Kind Regards,
