mbox-dedup.pl - A perl script to remove duplicate email messages from an mbox file. Especially useful if you've ever had Eudora lose track of where it is in regards to your POP server & pull down the same message multiple times.
I'm trying to repair a gigantic mbox file that appears to have been corrupted in that it displays only 17 of the most recent and total 3087 messages contained in the actual file.
