Google announced back in February 2016 that it planned to improve Gmail security by adding new security indicators to the service.

One of the improvements was the introduction of a new red question mark icon in place of the profile photo, avatar or blank icon to highlight unauthenticated emails.

Google announced yesterday that the roll out of the feature started, and that Gmail users on the web and on Android will soon notice the new red question mark icon for unauthenticated messages.

[...]

Google's method for determining the authenticity of a message is the following one: if a message can't be authenticated using DKIM or Sender Policy Framework (SPF), it is marked as unauthenticated.

Gmail, on the web, displays profile icons only when an email is selected, but not in the email listing itself. This means that you will have to click on a message to find out if it is authenticated or not.

    I will as soon as I set up DKIM for casaichiban.com. SPF is fairly easy. Making assumption that your mail server is 93.174.104.65, if you want to say all mail from soggywizards.com originates from 93.174.104.65, the DNS line would look like this:

    soggywizards.com.  IN TXT "v=spf1 mx a ip4:93.174.104.65 ~all"

    If using MS DNS, you'd create a txt record and then put everything that is in quotes, including the quotes

    This rule would say "If mail says it is from soggywizards.com but doesn't originate from this ip address, accept it, but flag it."
