Hi Doing a new server. In the past I would macgyver my setups so that the mail protocols, IMAP and SMTP would have valid certs. I do not want the new servers going forward to be macgyvered. I want to do things properly. So what is the correct way for the client to connect to email using SSL so that they get a valid cert for mail.theirdomain.tld? TIA
The intended way is to use the system hostname and not a subdomain of a client domain for this as subdomains of client domains do not scale that well. The SSL cert for the system hostname is created automatically when you install ISPConfig, so no further configuration needed. But if you want to use subdomains of client domains, then you could use something like this: https://www.howtoforge.com/securing...server-with-a-valid-lets-encrypt-certificate/
That's actually the MacGyvering I was doing before. Okay, I will keep to the current Regime then. Thanks for prompt reply... as always
