Issue Plesk and Letsencrypt

[Ralf Bieler]

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.

In Tools&Settings>SSL certificates (https://yourdomain.com:8443/admin/ssl-certificate/list), which certificate did you select for securing mail?
