Thank you for your help in advance! I am currently setting up an Exchange 2013 server, to replace our old POP3/SMTP system, however we would like to roll this out gradually when convenient for our staff.
Our plan is therefore:
- Setup Exchange 2013 to retrieve email via POP Connector - Done
- Setup Exchange 2013 to send ALL mail via a SmartHost - Issues
I have set the domains in Mail Flow > Accepted Domains to Internal Relay, enabled a Smart Host for * as the domain name, and disabled/deleted the accounts that are not setup yet; however Exchange just bounces the emails with no errors.
