mailMessages

The mailMessages is a collection of body parts contained in an internet message.  It has the following properties:

• Each body part is itself an internet message and represented by the mailMessage object.
• The body parts are separated by a boundary.
• Any text preceding the first body part is treated as the preamble and currently ignored.
• Any text following the last body part is treated as the epilogue and currently ignored.
• The main message containing the body parts must have a "Content-Type" header whose type must be "multipart".  Furthermore, the Content-Type header must have a parameter called "boundary" whose value specifies the boundary string that separates the body parts.

Basic structure:

Example:

Boundary Delimiter

A one-line string called the boundary delimiter separates the body parts in a composite or multipart message.  A boundary opens the beginning of the first body part and ends all subsequent body parts except for the last.  The last body part ends with a closing boundary.  The boundary delimiter is made up of:

• For the opening boundary and separation boundaries, the boundary string is preceded by CLRF and 2 hyphens ("--").

      <CRLF><"--"><boundary string>

  For example, if the boundary string is "some.boundary" then the delimiter is "--some.boundary".

   

• For the closing boundary, the boundary string is preceded by CRLF and 2 hyphens, and then the string is followed by 2 hyphens.

      <CRLF><"--"><boundary string><"--">

  For example, "--some.boundary--".

The boundary string is specified by the "Boundary" parameter of the Content-Type header that is in the message that encapsulates the body parts (or the mailMessage object that encapsulates this mailMessages collection object).  

The CRLF that starts the boundary delimiter indicates that the boundary MUST start at the beginning of the line.  The CRLF itself is part of the delimiter and not the preceding body part.

There MUST NOT be a text or a string within the body part that matches the boundary or closing boundary delimiter.  Framework EDI searches for the delimiter pattern to determine when a body part begins and ends.
