Question
Is it possible to secure Mailman on each domain separately?
Answer
By default Mailman uses certificate set up in Tools & Settings > SSL/TLS certificates. Mailman does not create individual configuration files for each virtual host. Due to this it is not possible to issue separate certificate for each domain.

Top-voted suggestions are likely to be included in the next versions of Plesk.
-
Log into Plesk;
-
Install certificate on Plesk panel in Tools & Settings > SSL/TLS certificates (for example, Let's encrypt);
-
Make it default:
Note: In this way all mailing lists will be secured by Let's Encrypt certificate, however, due to domain name mismatch (certificate is issued for hostname like example.com and Mailman uses lists.example.com) you will get a warning that certificate validation is failed.

The Let's Encrypt's wildcard certificate does not show in the Tools & Settings > SSL/TLS certificates.
Only the specific panel.domain.com certificate is listed there. therefore, selecting the Lets Encrypt there does not help -- the lists.domain.com still gives a warning to users that there is a name mismatch. How do I select the correct wildcard let's encrypt as the defult since it's not listed there?
@turgut , The certificate is not there because it was probably not issued. Please follow this article https://support.plesk.com/hc/en-us/articles/213954265-How-to-secure-a-Plesk-hostname-on-port-8443-with-an-SSL-certificate-Let-s-Encrypt-other-certificate-authorities-
