When I first installed my Cyberpanel 5-6 months ago, I did not plan on adding email to this VPS at all.

Now my needs have changed and I require email boxes on the server.

I didn’t choose the Full-Service install initially and said “n” to Postfix.

I’ve tried upgrading CyberPanel hoping that would give me the choice again but of course, it does not.

How can I safely get email support setup now?
