Great!

The main reason is that calling mailbox_append_message will trigger
scanning the entire user's mailbox, which is very ineffective now
and can slow down the delivery process considerably. On systems with
big number of users it will impose a considerable strain on mailservers.
That's why I went into all that trouble of opening mailbox stream and
delivering directly to it. In the short run I am going to implement the
new "append" mode for mailbox_open, which should make it possible to
use mailbox_append_message. This will simplify mail.local and make
it far more flexible.
