You can import the BATCH.TXT with import -r
It is even possible to import/convert mail by spl2fold, part of yutil04.
(Though this is not a reliable method.) The problems start when you want to
_send_ something. So, what we need is not a converter ka9q-soup but soup-ka9q.
There are several workarounds for this but unfortunately none of them
is really practicable.
