I think there is a way to do SNL with Certbot
I haven't tried this yet but it makes some sense;
https://community.letsencrypt.org/t/...ficate/20917/3
Code:
certbot-auto -d one.example.com -d two.example.com\
-d three.example.com -d example.org
https://letsencrypt.org/docs/rate-limits/
you might want to investigate this.
I'm thinking each group of domains needs to be on the same
IP and the .pem files need to be in that same place.
