It seems that you're encoding the file somehow - that's usual, even
required if your file is a binary file (like a picture, or a formatted
document).
In your mail headers, you should see some MIME like
Content-Type: multipart/alternative;
boundary=GU4wuTSk68F
("alternative" could also read "related" - depends on the content, the
"multipart" is the point here)
which would tell the client browser that the next mail consists of a couple
of separate parts, with a separator line as "--GU4wuTSk68F".
Next comes the message entity, which starts with such a separator line, and
a set of MIME headers for the respective entity:
--GU4wuTSk68F
Content-Disposition: inline
Content-Transfer-Encoding: 7bit
Content-Type: text/plain

That's the first part of the mail - it's plain text. The next part would be
an image, and again starts with a boundary:
--GU4wuTSk68F
Content-Type: image/jpeg;
name="sample.jpg"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="sample.jpg"

RHA0NjcxUFJGbzgtMTZsNDM=
--GU4wuTSk68F
The message should also end with a boundary, but most mail client's omit
this...

Hope this helps,
