- I do not have a Next, but someone I know mails me messages with
- embedding things like sounds, pictures, and formatted text. When I
- look at the raw mail files, they look exactly like uuencoded binaries.

- So, the first thing I do is uudecode them. This usually results in a file
- with a name like
-
- >.tar.148.jpeg_FAQ.attach
-
- Then, I proceed to assume that this is a tar archive of all the embedded
- objects, so I run this into tar to look at the list of files using syntax
- like:
-
- tar -tf .tar.148.jpeg_FAQ.attach
-
- This always gives me a table of contents error, or a "hmmm, this
- doesn't look like a tar file to me" error on the Next.
-
- I believe the first part was right, uudecoding the message, but what
- should I do with this binary file that comes out of it, that seems like it
- should be an ordinary tarfile, but isn't? Is this in some proprietary
- Next format, or are the technical details about this publicly accessible
- somewhere? I am a programmer, and would not mind writing a simple
- app for other computers to decrypt Next mail messages, but I have to
- know where to start.
-
- If anyone has any insight into this, please let me know, or tell me what
- publications to look at.
-
- Thanks - Tom
