I was already aware of. those mbox file just grow and grow until 
one does a 'Compress Folder'. There are additional complicated 
index files and caching and all. So it doesn't reflect the current 
state nor allows for practical modifying.
I found only SimpleMAPI for the inbox&send only. the XUL api seems 
to be usable only from inside.
