how to find duplicate emails in an mbox-mailbox
over the years I collected many mails with Eudora, Mozilla Mail and lately Ximian Evolution but some mails got doubled in the migration processes and I'm somehow not able to use Ximian Evolution in a way that my mails are filtered correctly.
Somehow all filtered mails are doubled each time but the mails I want to be in the certain subfolders aren't there.
Anyway this is not a complaint about this program, I wanna skip back to Mozilla mail but have trouble reimporting them because I have about 6000 mails which are in average about 1500 different ones.
So I concatted all the mbox-files evolution created together and now I'm looking for a program that find the duplicates and erases them.
So far Google didn't bring up any help and neither Ximian Evolution nor Mozilla Mail have this feature.
So, any ideas?
