This online tool is great for when you need simple to understand results and need to  analyze TLS/SSL issues regarding mail.

Other tools that I have mention a few years back are also  great

NOTE: They { luxsci } has  a HIPAA  secure email  solution that works great. This allows for selective delivery of  email  and mets HIPAA compliance.
