Rated 4 out of 5 stars

Totally excellent add-on! Works very well. The only thing I would recommend is an option for auto-splitting messages greater than 10MB into chunks.

I use it with the Enigmail add-on and the signatures even stay intact.

This review is for a previous version of the add-on (0.1.1). 

Hi and thanks for the review. How i wish there were such feature as "archive" splitting in the mozilla API but it does not provide any option to split created file, sorry. That's the side effects of a native API, but pros are a must: lightweight, x-platform, more stable. Regards.
