In the future, it would be cool if there were a mailbox format (dbox2?)

This would enable the zfs dedup feature to be used to maximum benefit.
This is more or less what dbox's single instance storage is going to do.
Maybe in half a year or so.. And you don't even need filesystem
deduplication feature. :)
But if the mail system has to handle it, it only knows about mails
written at the same time. For example, if postfix delivers mail
with a single recipient per mail (the recommended config somewhere,
not sure if recommended by postfix or by dovecot), dbox won't get
the opportunity to dedup.
And for mails which are re-forwarded (pretty common occurrence), again
dbox won't get the chance to dedup.
Or will there be a global index?
