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.
