Great Tool - Some Odd Behaviour? Rated 5 out of 5 stars
This is a fantastic tool that is really needed - particularly in a busy business environment.
There has been one change in behaviour recently. Running against a dovecot IMAP server with around a couple of hundred folders containing tens of thousands of emails, if we select "Review Search Results Before Deletion" everything works fine (although someone has to be here to press the button). If we un-tick this option, it finds no duplicates whatsoever. Nothing. Nada. I have tried playing around with all the other options but to no avail.
That's about the only failing I have found and it appears to be a newly introduced bug - older versions worked perfectly.
I'll give it 9/10 - it would have got 10/10 except for the minor hiccup.
