I have a web server on a domain eg example.com On this webserver is an exim server whose only job is to send email to one particular user eg firstname.lastname@example.org
However the pop mail server is hosted elsewhere.
How do I configure exim on the web server to send email that has the same hostname to a different server?
When I do exim -bt email@example.com I get
R: system_aliases for firstname.lastname@example.org email@example.com is undeliverable
The webserver hostname/mailname is set to example.com
Server is running Ubuntu 12.04
