Rated 5 out of 5 stars

I had written a review commenting on how this add-on was causing my email to be detected as SPAM. The developer contacted me and explained how I had the "Junk Travel Time Filter" enabled which caused checks that took too long to be reported as spam. I have turned this off and it did solve the problem. I am impressed with the professional and timely response to my review and am very happy to have the feature back.

This review is for a previous version of the add-on (4.4.0).

I love the functionality, it is nice to see a map of where the hops are and how they got to me. It's easier than ferreting it out of the headers. However, I have found that it causes many emails to be falsely identified as spam. I had to remove it from my system.

I'm suspecting that you have the Travel Time Junk filter on which flags messages as junk if travel time takes longer than normal (10 seconds). Try turning this off.
