Gmail will soon be able to alert its users to any emails that arrive if they are under an unencrypted connection (ssl).
Google already uses HTTPS to use gmail, in order to ensure the encrypted connection between the user's web browser and its servers. Also, Google and other e-mail providers have begun encrypting the links on their servers. But not everyone, at least not yet.
A Google research program in collaboration with Michigan University and the University of Illinois found that email security has improved over the past two years and that 94% of incoming messages to Gmail comes along with some form of identity. But there is still a 6% moving without certification.
Google found it also malicious DNS servers that serve fake routing information on email servers.
To protect its users, Google has decided to warn email recipients which of their incoming emails are not encrypted from the beginning to the end. This feature is expected to come in the coming months.
