I am still rather new to linux, but have set up a landscape server (free, on premise) to manage a number of other Ubuntu 16.04 Servers.
During the install, I didn't specify any SMTP details, hence now my landscape solution cannot email invites for new user accounts.
My question is, How do I / can I reconfigure the landscape SMTP settings, now the server has been configured, or will I need to remove and re-install landscape?

Turns out the answer was to run
sudo dpkg-reconfigure postfix
