I have installed MIAB on a fresh DO droplet installed all SSL certificates via Lets encrypt. configured all the Nameserver , DNS records and glue records. say domain Example1 and MIAB host name is box.example1
Now I want I want to have one of my website (example2) which resides on another droplet and want to configure MIAB with the above installation. So for this
I will change the name server of the (example2) to the (box.example1)
2) now when I configure MIAB mail for user of the (example2) mail - then where do i need to configure SSL certificate in (box.example1) or in (example2) via lets encrypt.
I am bit confused as where to set the SSL certificate or if I am doing this the other way.
Thanks for all the help in advance.
