  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue Plesk and Letsencrypt

Hi all

hope I can find some help.

My problem:
Running a server with actual 5 Webspaces and Domains.
All of them are secured with letsencrypt and running fine.

But, sind an update of Plesk I think, i am not able to use emails with ssl / tls. It looks like thunderbird is only checking the certificate of plesk itself, not for the domains. So i get a waring for each mail i want to receive and i am not able to send mails.

Anyone know this problem and can help?
Thx a lot
 
thunderbird is requesting ssl certificate of plesk instead of the used domain
 
That is the expected and correct behavior. You only have one mail server that runs on the main domain of the host. The SSL certificate to protect that mail server is made out to the main domain of the host. As your mail-in (IMAP, POP3) server and your mail-out (SMTP) server, always use the host name of your system, not individual domain names. You do not have a certificate for the mail service for individual domain names.

It it has previously worked in Thunderbird, there might have been an exception rule in place in Thunderbird.
