Unfortunately the aoximport shell command doesn't support incremental 
loading.

I guess we could write a script that parses the mbox and adds whatever 
is missing, as long as we keep it as a last resort if we can't make the 
primary delivery a fail proof.

My main concern is that we'd need to overcomplicate the thread detection 
algorithm so that it better deals with delayed messages: as it currently 
works, the replies to a missing message get linked to the 
"grand-parent". Injecting the missing message afterwards will put it at 
the same level as its replies. If it happens only once in a while I 
guess we can live with it, but definitely not if it happens tens of 
times a day.
