This fails your "does not create random files on disk" requirement, but
you can use munpack to expand a multi-part MIME email into (ahem)
multiple files on disk:
munpack -tC randomFilesOnDisk/ ~/multipart.eml
-t Give me the text part of the email as well
-C Change into this directory first (which is why the
fully-qualified path to the email file is required
When the email contains html with embedded images, munpack does not
alter the image links to point to the random files on disk. You'd need
to script that part.

Is there a command line program which can extract the first attachment,
or even the first attachment of a given type? Reading stdin and writing
stdout would be an extra bonus, though it would be possible to script
around that. Important is that the program does not create random files
on disk (files with names supplied by the input email are considered
random).
Thanks,
