* When the function is unable to parse the @mime_part (either because it's broken
* or because it is a different mimetype then the extension is specialized for), the
* function will return @NULL indicating the #EMailParser, that it should pick
* another extension.
*
* When the @mime_part contains for example multipart/mixed of one RFC822 message
* with an attachment and of one image, then parser must make sure that the
* returned #GSList is correctly ordered:
*
* part1.rfc822.plain_text
* part1.rfc822.attachment
* part2.image
*
* Implementation of this function must be thread-safe.
*
* Return value: Returns #GSList of #EMailPart<!-//>s when the part was succesfully
* parsed, returns @NULL when the parser is not able to parse the part.
