Increase SMTP security and stop man-in-the-middle attacks with MTA-STS

Published by Red Sift

MTA-STS (Mail Transfer Agent Strict Transport Security) is an email standard that enables the encryption of messages being sent between two mail servers. It improves the security of the SMTP protocol by specifying to sending servers that emails can only be sent over a Transport Layer Security (TLS) encrypted connection which prevents emails from being intercepted by cybercriminals.

Google and Microsoft both support MTA-STS and TLS-RPT.

In this blog article, we’ll walk you through the steps required to manually deploy MTA-STS. (Spoiler alert: there’s an easier way to deploy the MTA-STS protocol. Scroll down to the bottom of this post to find out more.)
