When either of two of our admin logins attempt to add a new admin user and select to send an activation email, we get this error message:
Internal Server Error stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
Why is Craft CMS attempting to connect with SSL3 which is intentionally disabled at the server level due to known vulnerabilities?
