Where does this trigger scanning of the mailbox? I had a look at mbox.c 
and could not find where it scans the mailbox. But assuming that it 
does, why does it do it? I suppose I am coming from a maildir mindset, 
but I can't see why you would have to scan the entire mailbox to add a 
message.

Ok, so this is different than opening the mailbox with MU_STREAM_APPEND?
