Review for MailHops by Kent Linkletter
Rated 2 out of 5 stars
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.
This review is for a previous version of the add-on (4.4.0).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.
