I'm facing some issues on mdbox based backups. Backups are failing with dbox corruption messages. SiS is the greatest advantage though. However backups integrity is very important. If SiS/Deduplication is not a requirement stick to Maildir.

It can be faster when a user deletes or moves a large number of messages.
One reason why I migrated a few sites is that when reporting issues with maildir on this list, there seems to be lack of interest in fixing them. In that regard, it can be seen as a safer choice.
