Problem with letsencrypt certificates for services
On upgrade or installation ISPConfig asks to configure the services with letsencrypt certs. It links the services certificate files to the ISPConfig interface certificates, which are linked to the hostnames cert.pem in the letsencrypt live folder. This causes issues for example with mail clients (trust anchor for certification path not found).
Services like postfix or dovecot should use the fullchain.pem in the letsencrypt live folder.
