Mostly good Noté 3 sur 5 étoiles

I am switching hosts and since I want to keep all the emails I have so far, I had to switch to POP3 (another TB nightmare). I ran this extension and I think it removed some, but it it left many more duplicates - yes, duplicates, same message.

Cette critique est pour une version précédente du module (0.3.5). 

They're not really duplicates

I often get this complaint. And it's always the case that the messages are just similar, not the same: An extra newline, a few seconds time difference etc. Try using fewer comparison criteria...
