Excellent and useful, thanks.
Is there an option to get the .zip extension automatically turned into .zi_ , so that the mail can pass through antiviruses or filters (in my company for instance, I can't receive a mail with a .zip file in it. But .zi_ works well)? Thanks

This review is for a previous version of the add-on (0.1.0). 

Thanks for the review. I will consider adding such feature in next release (next version is coming soon, i've fixed a few bugs), certainly in 'advanced' tab. Regards.
Edit: This feature has been added in v0.1.1.
