Messages notes
Each message can have a private text note attached to it. Notes can
be viewed and edited within the user interface, by any user.
They're kept private to the database (aren't included if the message
gets forwarded, for instance).
A common use of notes is to attach comments or reminders to
the incoming mail.
It is also possible to use them on pending outgoing messages as an
"off channel" communication mean between users, when several people
have to write or acknowledge a common reply before the actual sending.
When a note is attached to a message, an entry is shown in the
attachments view, with an "Internal note" type where the mime type
would be for a normal mail attachment, as shown in the picture
below:
Adding or updating a note
Use the Message/Edit Note command while the message is selected
or being composed, or double-click on its line in the attachments view.
This will open a
non-modal dialog window looking like the picture below:
Deleting a note
Deleting the whole text of the note has the effect of removing it,
as well as hitting the <Del> key when the note is selected
in the attachments view.
