Google announced this week that Gmail has become the first major email provider to support two new security standards, namely MTA-STS and TLS Reporting. From a report: Both are extensions to the Simple Mail Transfer Protocol (SMTP), the protocol through which all emails are sent today. The purpose of MTA-STS and TLS Reporting is to help email providers establish cryptographically secure connections between each other, with the main goal of twarthing SMTP man-in-the-middle attacks. SMTP man-in-the-middle attacks are a major problem for today’s email landscape, where rogue email server operators can intercept, read, and modify the contents of people’s emails. The two new standards will prevent this by allowing legitimate email providers to create a secure channel for exchanging emails.
