I’m trying to setup a multi-domain certificate. In the admin panel it says:
Install a multi-domain or wildcard certificate for the box.domain.com domain to have it automatically applied to any domains it is valid for.
I purchased a multi-domain ssl from namecheap “POSITIVESSL MULTI DOMAIN”. Used the hostname box.domain.com and installed the certificate including the intermediate chain by clicking on “Install certificate” on box.domain.com.
Accessing the webmail from domain.com/email still warns that the certificate is not signed and the same it says in the System Check page. The only domain that has the certificate is box.domain.com
How can I make the certificate work for the rest of the domains ? It says that is supposed to be automatically but doesn’t work and I haven’t setup one before.
