Question SSL-Certificate

[Shigeno]

So I recently moved a homepage (wordpress) from a webspace to a linuxserver with plesk. Anything seems to be working as supposed. Then someone installed a lets encrypt for the domain, which works fine. So after one week users told me they are having problem with their mails accounts. So I checked it and found out the smtp and imap server are using the default plesk certificate, which gives you a warning, because they are used for a different hostname. Any idea how to fix this? Because I choose the right certificate for the mails, but the mail programms tell me they are using a different (plesk default) one.
