Strange combination, but the first message with multipart/alternative
also contained a .scp file and not as an attachment.
The template for multipart/alternative allows switching between the
alternatives.
For now we just save them unmodified and give them an extension that
will cause the web server to provide the correct content-type. This is
probably *not safe*: A user could send malicious html as an attachment
and the browser will interpret it when another user clicks on the link.
We might try to sanitize attachments (but you would normally expect an
attachment to be preserved) or to preserve the content-dispostion header
(but I don't think this is possible with just a static archive).
This doesn't handle the case where total isn't present on all parts, but
I don't actually expect to encounter that (and if I do, it will crash
and I can fix it).
Parses all mbox files on the command line and extracts message ids from
Message-Id, In-Reply-To and References headers.
Just a test script to see what message ids look like in practice.
