Issues with Neomutt SMTP configuration

I have the following things not working in my neomutt application: 1. Email is displayed instead of Username. For example : johndoe@example.com is displayed instead of John Doe . 2. How to ensure that Neomutt applies the Standard TLS encryption for security similar to Gmail, which encrypts emails on transit? Neomutt MSMTP config

account johndoe@example.com
host smtp.gmail.com
port 587
from johndoe@example.com
