Rated 4 out of 5 stars

Hi Christopher, I just discovered this addon but I miss a functional combination of its great possibilities: export all messages of a folder and its subfolders (hierarchical) in *.eml format. It would be a great thing if you could add this feature.
Best regards and much thanks!

This review is for a previous version of the add-on (4.0.4). 

Thanks for the review!
I actually have this as a possible enhancement. You can track it here:

This is a sensible addition I just have to try and find the time after all the bugs coming in!
