I just made it through this helpful article and successfully have my mail server set up with a single domain.
What I'm wondering now is how I can be able to add multiple email account for different domains.
To add a new email account currently, I would use the command:
useradd -m john -s /sbin/nologin
That would allow me to have an email that looks something like email@example.com.
What would I do if I wanted multiple domains? (like firstname.lastname@example.org)
Thanks, I'm still completely new to the world of VPS:)
