I’m attempting to create an ssl certificate for use on my mailserver which is at mail.felinesoulsystems.com. I’d like to have one certificate for postfix and courier (i’m aware that i need to cat the keys together for courier). Looking at this Configure courier-imap that’s great info, but it doesn’t tell me how to create the certificates using certbot.
How to i tell certbot to create a certificate for mail.felinesoulsystems.com that is not directly related to a webserver and that webserver files don’t need to be altered. I just want to create certificates in /etc/letsencrypt/live/mail.felinesoulsystems.com?
