Rated 5 out of 5 stars

I use Thunderbird for work and 3 personal email accounts, all use IMAP. Mail for all accounts are filed in local folders for speed as Thunderbird always seems to retrieve the original even if I have it cached locally. Because everything is kept in Local Folders, native TB always uses the default account at the From rather than scanning for which email the message was originally sent to.

The one feature I could request is the ability to pick the correct From when I reply-all to a message in one of my Sent folders. This still uses the default From.

This review is for a previous version of the add-on (1.3.1).
