email session encryption fails in a private ca environment
when configuring email notifications, and enabling encryption, message notifications fail if the certificate provided by the server is signed by a ca other than those listed in /usr/local/share/certs/ca-root-nss.crt. this prevents use of a private/internal root ca.
please provide a mechanism for use of a private/internal root ca. this could be done similar to the auth/ldap server settings [system -> user manager -> authentication servers -> ldap server settings] system_authservers.php, or, imho, better by allowing augmentation of the system's root ca cert store [see feature #8373]
