That was a fairly dumb question on my part - it was getting late when I
asked it.

I've run a short (12 message) test file through spamassassin using the
--mbox option and capturing the output in another file. My
JavaMail+mstor application read the output OK. I'm currently putting my
very large, torture test message collection through spamassassin and
will write a fuller description when it finishes and the output has been
fed into my application.

Thanks for your help.
