Review for MailHops by Stuart Gathman
Rated 5 out of 5 stars
What no one has mentioned is that when your MTA supports email authentication (DKIM or SPF), MailHops displays the results, and the details are visible with hover. No more clicking on "View Source" to find the authentication headers. The hops is handy, and the map is just eye candy but fun.
It seems to look at both Authentication-Results and Received-SPF.
Question: how does it determine whether these header are trusted? Does it assume the MTA either strips or adds to the top?
Bug: when the geoip route lookup service is unavailable, the Hops dropdown should still be populated. The route and map are just eye candy, not essential.
