Following a successful (I thought) set up of Exchange 2013 and Domain controller, both as virtual machines on the same physical Server (LeNovo), also running Server 2012, after much experimenting and checking of settings we cannot get emails to send from Exchange 2013.
Other things to note are: -
The incoming emails are routed through a program called POPcon as the emails are from a service provider who does not provide an SMTP feed. i=Incoming emails seem to work.
We have configured two DNS servers, one being the Domain controller (virtual Machine) and one being the physical Server where the two VMs reside. The second DNS server was configured after we were exhausting possibilities for resolving this issue and thought it might help...!
Certificates that were working, stopped working and have become untrusted, requiring a reset.
Outlook can connect to Exchange from the workstations
Emails are coming in
Mobile phones won’t connect/synchronise
I am thinking that the other issues will resolve once we sort out the SMTP send problem, and that is my first objective.
When attempting to send, emails appear in the 'drafts folder. This is well documented and the reason given is related to DNS configuration, but having read a number of the fixes, all seem to suggest the DNS is poorly configured. I am ready to accept I have configured this wrongly, but cannot find out what is wrong. The Exchange Server can access web sites and it can ping web sites by name.
Furthermore the emails that get queued up in the 'Drafts' folder do eventually get sent typically about 8 hours later.
If you think it is a DNS configuration issue. What should I be checking?
Your help will help close down the longest server install I have ever been involved with.
