* attachments position within the list of multipart/mixed elements. This would make every POP3
* attachment unique, and might also simplify the code (since we could just look at the positions,
* and ignore the filename, etc.)
*
* <p>TODO: Take a closer look at encoding and deal with it if necessary.
