Hello there, I recently installed an ISPConfig on a clean debian 10 (both latest versions). For the panel I made a webdomain login.domain.tld and got a LE Cert. After that I installed the ordinary page domain.tld. together with some subdomains like mail.domain.tld etc. Now if someone uses domain.tld in his email server settings he will get a cert error because the DNS-Name login.domain.tld (which I also use for MX) is not in the certificate list, what is kinda understandable. My question now is: How to join the login. subdomain to all the others? My solution would be: - backup /etc/letsencrypt - delete webdomain login.domain.tld - delete login.domain.tld with the "certbot delete" command - make a subdomain login.domain.tld in ispconfig and activate LE SSL Do you expect any errors or any flaws with my solution? Are there some disadvantages? Should I keep it and change the MX-Records?
Tell them not to do that. Instead they should use login.domain.tld as e-mail server, if that is what you have set up. There are other solutions, but I would say they are worse and do not scale. Search old discussions on this forum.
That was my point, too. But you know how customers are. It also has no priority for me. Everything is working just fine - as always with ISPConfig. It's just a thing "why would you do it? - because I want to." It's about thinking about possible problems and finding solutions. Thank you for your answer.
