Very good!
Please, if possible:
1) User can select mail account to backup (I have 7 mail accounts).
2) User can select filter subject field or (and) from field to backup.
3) English, please...
Thank You! :)

This review is for a previous version of the add-on (0.1). 

now, update this addon.if you use version 0.2.0, you can use filtering mail by mail account/address.
thank you (^^).
