how do I open mime attatchments?

It is not something you can really open and view. See attached from Apple KB:

All email attachments must be encoded with the message before the message is sent. Attachments are encoded with MIME and decoded when received. When seeing MIME attachment, this usually means the attached file is not recognized by the computer or device that received the message - there is no application available that recognizes and can open/view the attachment.
