Amidst the continuing Apple-FBI controversy, a number of the largest technology firms have joined forces to produce a fresh e-mail mechanism called SMTP STS that’s geared toward making user information protected.

Google, Microsoft, Yahoo!, Comcast and LinkedIn have jointly submitted a suggestion to the Internet Engineering Task Force for SMTP (Simple Mail Transfer Protocol) STS (Strict Transport Security). The system also tests if the encryption certificate is genuine and updated, and checks in the event the domain a user is sending an e-mail to supports SMTP STS or not. If for some reason the mechanism find any trouble, it certainly will allow the sender know the motive and wouldn’t permit the e-mail pass through.

E-Mail has long been among the primary sources of digital communication, but with the growth of workplace cooperation programs, instant messaging programs, and social networks, it’s losing its dominance. It’s always a good idea to see companies such as Google and other working on encrypting e-mails to make the private more safe. Google itself uses the encryption process for its Gmail e-mail service.

Additionally, Gmail will flag e-mails received from contacts whose identity can’t be confirmed. The service will alarm the recipient about the e-mails coming from unauthenticated sources by revealing a question mark in place of the profile picture of the contact.
