Hello everyone! This is a newbie problem that I am hoping someone can
give me a hand with.
Overview: I am trying to set up a Exim to be used as a MTA for sending
out my clients marketing and informational emails. These emails will
come from in-house applications either through "sendmail" interface or
via TCP/IP. I will need to support TLS for sending. As such it should
be a fairly simple setup. I have changed my domain to example.com in
the posted information. I am defaulting to giving too much info in
this opening email, as I am not sure what will be of most benefit in
aiding me. As such, I have also posted the complete config file at
the bottom of the email.
Problem: When sending emails as described above, they are not leaving
from Exim to the destination, they are remaining in queue.
Description: Viewing the log does not give me much to go on. In
preparation for this plea for help email I have cleared all logs and
queues to limit all information to just what I am mentioning here. To
reiterate, if I am posting it, or responding to you, the information
will only relate to the two emails I am mentioning herein.

Below is what sending to an email hosted by google gets.
