I have domain example.com and I should protect hrl https://mail.example.com
Code: Select all
Add the new domain, in this case example.com. Set zimbraVirtualHostName to mail.example.com and zimbraVirtualIPAddress to 18.104.22.168. Make sure the zimbraVirtualHostName is set to the name which will be used to access the domain (URL) and the SSL certificate is signed for the same name.
zmprov md example.com zimbraVirtualHostName mail.example.com zimbraVirtualIPAddress 22.214.171.124
I will use letsencrypt.
My doubt is: should I get a letsencrypt cert for example.com or for mail.example.com?
Or should I get 2 certs, one for example.com and one for mail.example.com?
Please advise as I am very confused
My best regards
