Rated 5 out of 5 stars

This worked great to import some old sent emails that I had lost when I switched over to Gmail from two other email servers that I had deleted after the switch. It brought in all the emails from the deleted servers Mail > Sent folders lickity split and dumped it all into a new Sent folder, then I could move it all over to a Old Sent folder for future reference.

Thanks to all who created this Add-On!
