I am using Lets Encrypt to issue SSL certificates on my Ubuntu 16.04 server that uses ispconfig.
When I add an email account to Thunderbird email client I get the following message:
This site attempts to identify itself with incorrect information
If I view the certificate Thunderbird reports that the certificate is issued to and issued by is
Common Name is ubuntu-1.mediamix-nj.com
Organization is Servisys di Temporini Matteo
Any idea of what is wrong?
Thanks in advance for your help.
