Today I accidentally copied my mails into the same folder where they had been stored before (evil keybinding!!!) and now I'm faced with about a 1000 copies within my inbox. Since those duplicates do not have a unique mail-id, it's hopeless to filter them with mutts integrated duplicate limiting pattern. Command '<limit>~=' has no effect in my case and deleting them by hand will take me hours!
I know this question has been (unsuccessfully) asked before. Anyhow is there is a way to tag every other mail (literally every nth mail of my inbox-folder) and afterwards delete them? I know something about linux-scripting but unfortunately I have no clue where to start with and even which script-language to use. This close-to-topic approach with 'fdupes' has been released some time ago (http://consolematt.wordpress.com/tag/fdupes/) but in my view it seems way to complicated. As I could recognize from mutts mailing archive, I'm not the only one who has had trouble with it. Therefore I appreciate any hint which drives me into the right direction and helps me solving this. Running Mutt 1.5.21 under Ubuntu Gnome 13.10. (Linux 3.11.0-13-generic). cheers, jonas
