  Here is a little doc from WHM: Mailbox Conversion | cPanel & WHM Documentation To me the biggest question is backups. maildir stores each email received (or sent) in it's own file. mdbox is one big file containing many messages (like an Outlook .pst file). If you are running incremental backups it's going to be a lot easier/quicker to backup maildir (you'll only pick up the changes) vs mdbox (you have to backup the while file + any new ones created). Your going to end up with less corruption with maildir (if you have any issues). The worst thing that can happen is that the Dovecot indexes get messed up and those are easy to rebuild. If a mdbox file gets corrupted, it's prob. going to be more difficult to fix. The downside of maildir is the WHM transfer system. Rsync can take a long time with a lot of little files and that's exactly what maildir is. My 2 cent!
