Pros of Mdbox:
* uses less files, meaning MUCH faster backup, faster fsck
* you can use ALT storage, namely saving certain folders on a 
faster/slower storage (e.g. Inbox on fast RAID and rest on slower RAID)
* you can compress it, making it even faster (zlib and so on)
* uses much less I/O-operations compared to Maildir

Cons:
* you need to use the doveadm-toolchain, so you need to learn it; no 
longer mingling with emails on file system level anymore!
* you need a snapshot for a consistent backup
* if you lose the index file, all information on folders/mails is lost
