You are on your own if you do this. Although the format of spool files
is documented, it is not guaranteed to remain unchanged. You need to
understand about locking, you need to keep all the data in the -H
file correct, and you need to ensure that the message is syntactically
valid (correct MIME parts, encoding, etc). Doing this will almost
certainly break signed messages.
