Method for Protecting Distribution Portions from Third-Party Removal

      Provided is a mail system service for allowing an author of a
mail note to specify portions which are read only.

      Often, within a network of users which use electronic mail,
distributions are forwarded to users with information which the
originator would like to ensure remains with the originally edited
note.  Recipients may resend a note to other users and edit out
portions of the original note.  A method is needed whereby an
originator of a note can guarantee portions within the note will
remain, regardless of who receives the note and what they try to do
to it before sending it on.

      The user can highlight (e.g., mouse stripe) portions within a
note and assign a protection attribute.  The attribute is associated
with the note in the same manner other attributes such as recipient
list, document name, etc. are associated with the note.  The
attribute is a byte offset from the beginning of the note and the
length in bytes of the protected area.  The receiving mail system
inbasket management code allows a user to peruse the mail note but
enforce not being able to alter protected areas as indicated by the
associated attributes.  Thus, resending the note with edits to
another set of users will guarantee protected areas remain in the
note as requested by the original author.
