TLS and Webmail

[bare]

Hi,
I captured the trace for for yahoo and gmail and all the email packets were sent using SSL and TLS. can i develop these webmail application without SSL and TLS features. I am developing this application on a bare machine(i.e no OS required to run the application) and i do not have TLS yet.

SSL/TLS will only be used if the receiving MTA supports that functionality.
