I have a MAC OS mbox file. Each user has his own folder and each folder has a file named "mbox" in it. how can i convert this single large mbox file to individual email files, like the directory structure readable by courier imap server?
Search google for "mbox to maildir conversion". This is one of the hits:http://untroubled.org/mbox2maildir - as I remember, the one I used when I had to do a similar migration.
