I have two droplets at digitalocean, the first is mail in a box (box.mydomain.com) and the second one is my web server (mydomain.com).
I created A record with
curl -X PUT -d "x.x.x.x" https://box.mydomain.com/admin/dns/custom/mydomain.com
so that mydomain.com points to my web server machine.
No problems there, mail server works and I can reach web server at mydomain.com
(System Status Check says - Web has been disabled for this domain because you have set a custom DNS record, I guess it’s ok)
Is it possible to use ssl certificate generated with mail-in-a-box on nginx server on mydomain.com?
I’ve created valid SSL certificates for both box.mydomain.com and mydomain.com when installing mail-in-a-box. (Although now Certificate Status for mydomain.com on TLS (SSL) Certificates says: The domain’s website is hosted elsewhere)
Should I copy ssl keys from box.mydomain.com /home/user-data/ssl to mydomain.com server in order to configure nginx:
listen 443 ssl;
