33.9 Rmail Attributes
Some labels such as ‘ deleted’ and ‘ filed’ have built-in
meanings, and Rmail assigns them to messages automatically at
appropriate times; these labels are called attributes. Here is
a list of Rmail attributes:
‘ unseen’
Means the message has never been current. Assigned to messages when they come from an inbox file, and removed when a message is made current. When you start Rmail, it initially shows the first message that has this attribute.
‘ deleted’
Means the message is deleted. Assigned by deletion commands and removed by undeletion commands (see Deleting Messages).
‘ filed’
Means the message has been copied to some other file. Assigned by the
o and C-o file output commands (see Copying Messages Out to Files).
‘ answered’
Means you have mailed an answer to the message. Assigned by the r
command ( rmail-reply). See Sending Replies.
‘ forwarded’
Means you have forwarded the message. Assigned by the f command
( rmail-forward). See Sending Replies.
‘ edited’
Means you have edited the text of the message within Rmail. See Editing Within a Message.
‘ resent’
Means you have resent the message. Assigned by the command M-x rmail-resend. See Sending Replies.
‘ retried’
Means you have retried a failed outgoing message. Assigned by the
command M-x rmail-retry-failure. See Sending Replies.
All other labels are assigned or removed only by users, and have no standard meaning.
