One major advantage of mbox (and now mdbox) over maildir is the time it takes to back things up for larger mail stores.
It takes much less time to compare a single mbox file that contains 20,000 messages (and rsync only the changed bits) than it does to compare read/compare 20,000 individual files (maildir)...
I too like maildir, but am seriously considering implementing a solution where older mail is automatically archived to slower/cheaper SATA III based storage using mdbox format.
Very interesting. I use "rdiff-backup" as a cronjob in the wee hours (, so the fact it takes a while to work out what to incrementally save, doesn't matter to me -- but the point is that I know it's an issue and have addressed it that way.
I too have contemplated some automated archiving of older mail . . it's getting closer to needing to be addressed at some point soon I think.
