I'm hosting several domains on my server, all the webstuff is secured by Let's Encrypt. Now I want to use thunderbird to access mails on different domains (imap). I found the plesk setting for securing the mail server itself, but I can only select one certificate there. So if I use the certificate of one domain, it works for _that_ domain, but not for the others. If I set it to "default certificate (Serverpool)", it uses a Plesk default certificate (Parallels blabla). How can I use different certificates for the different domains?

That would be a question for Plesk support channels, however you can also get a certificate from Let's Encrypt with multiple DNS names (domains) such that you only need to upload one certificate. If this forum knew the ACME client you were using we could provide instructions for getting such a certificate.

I just checked, I have the Plesk Let's Encrypt plugin installed, however it redirects me to the SSL it! plugin... is that the ACME client you mean?

I have found it is a lot easier to choose one FQDN to serve as the canonical hostname and just have your domains use that as the mailserver hostname rather than setting up vanity names for each virtual domain for no real reason. If you have a generic-sounding or hosting-related domain, I would choose that one That said, if Plex supports listening with TLS on multiple domain names, you should be able to do it.

Whether or not you could use a single certificate with all of the desired domains will depend on how Plex handles the configs in that situation.

I'm sorry that I have nothing Plex specific to offer.
