I am not sure I understand why it would be "read entirely", as it is the same as reading a message when accessing a folder and writing a file when a new message in arriving.... which is the very most common activity of a mail server... so not sure about any "wasteful" I/O
Can we spend some more thoughts on this ?

Is there a way to use the mdbox format (i.e. several message per files) for EACH IMAP folders (sdbox approach) ? The problem with that is that when copying messages between mailboxes they would have to be actually read and written entirely, rather than a) with sdbox it can use a hard link() call, b) with mdbox it can update 3 indexes. Copying is a rather common operation since clients often move messages to Trash, so the extra writing would be a bit wasteful.
