No, that's not my point. It's just that milter-greylist attempts to 
add a header in each mail telling why it was greylisted. This is done
through these EXF_* flags. If you don't add one (and add the header
later by looking at the EXF_* flags), then the header will not be there.

Bo basically we won't be able to open it if it's been written? Then we need
to loop until we can open it, don't we?
