Review for Awesome Auto Archive by Jim
Rated 5 out of 5 stars
I was so impressed that I contributed some cash.
It does exactly what I wanted, allowing me to choose between copying and archiving from my IMAP account to my local folders.
In my case I choose to copy messages as a form of backup. There are great filters to allow you to select the age of items etc. It all works great.
Thanks to the developer for a great addon!
