When registering via email, a message appears indicating that SSL/TLS connections to the SMTP service are not supported.

The server-side technology stack is outdated (Java 8), and currently, email registration displays a message indicating that SSL/TLS connections to SMTP services are not supported.

Most mainstream email services now require SSL/TLS.

Shouldn't the development team consider this?

Start at the server-side email registration flow and the SMTP error path described in the issue. Determine how the Java 8 runtime handles SSL/TLS connections and which mainstream SMTP services must be supported; done means registration can send email through those services without reporting that SSL/TLS is unsupported.
