I have a LetEncrypt Certificate enabled using the excellent tool provided within VirtualMin:
Server Configuration / Manage SSL Certificate / Let's Encrypt
It works perfectly for those domains which it lists in "Domains associated with this server":
But I still have issues with important subdomains of the site, including "mail":
The "*" being especially important, as I can not currently receive mail through the site using client software.
Is there an easy way to add the four required subdomains to the certificate?
My plan was to merely complete the "Domain names listed here" section of the Let's Encrypt page with the two existing "Domains associated with this server" while adding the new domains. However, I'm worried that this will break everything. I mean everything: government everywhere crumbles… the world thrown into anarchy… puppies cry… that kind of thing.
