Rated 4 out of 5 stars

This add-on is great when I've received an email to the "wrong" account, and move it over (or filter it) to the folder for the right account. Then the replies will use the right return address, if I have the message's *own* folder selected. But there is a problem if I have several messages open, from different folders. If I don't watch out, the from address will use the folder I have selected, for the last message I opened, different from the message I am replying to. That is just as bad as using the address from the message itself, which is the problem I wanted to solve.

.Now I'll admit that it does what the description says it will do, but I just wish it did something a little different (and the description was likewise different.)

This review is for a previous version of the add-on (3.0).
