Does anyone know of an existing script/tool that can successfully split mbox files and maybe output them one by one to stdout or something? It's not quite as easy as splitting on the cutom "From " marker that mbox uses (From+ space, not From: ) because that could be in the email itself so I guess some additional heuristics are required for accuracy anyway

I'm sure I could whip up something with Perl but there's gotta be a tool out there already that can let me iterate over the messages in mbox format
