FolderFlag Fields

This folder presents all messages in the user's message store (\All). Implementations MAY omit some messages, such as, perhaps, those in \Trash and \Junk. When this special use is supported, it is almost certain to represent a virtual folder.

This folder is used to archive messages (\Archive). The meaning of an "archival" folder is server-dependent; typically, it will be used to get messages out of the inbox, or otherwise keep them out of the user's way, while still making them accessible.

This folder is used to hold draft messages - typically, messages that are being composed but have not yet been sent (\Drafts). In some server implementations, this might be a virtual folder, containing messages from other folders that are marked with the Draft message flag. Alternatively, this might just be advice that a client put drafts here.

This folder presents all messages marked in some way as "important" (\Flagged). When this special use is supported, it is likely to represent a virtual folder collecting messages (from other folders) that are marked with the "\Flagged" message flag.

The presence of this attribute indicates that the folder has child folders that are accessible to the user (\HasChildren).

The presence of this attribute indicates that the folder has NO child mailboxes that are accessible to the user. If a folder has the NoInferiors attribute, the HasNoChildren attribute is redundant and SHOULD be omitted. (\HasNoChildren).

This folder is where messages deemed to be junk mail are held (\Junk). Some server implementations might put messages here automatically. Alternatively, this might just be advice to a client-side spam filter.

The folder has been marked as "interesting" by the server; The folder probably contains messages that have been added since the last time the folder was selected -or- has a non-zero RECENT message count. (\Marked).

It is not possible for any child levels of hierarchy to exist under this name; no child levels exist now and none can be created in the future (\Noinferiors). This flag also implies HasNoChildren.

Indicates that a folder name does not refer to an existing mailbox (\NonExistent). This flag also implies NoSelect.

It is not possible to use this name as a selectable folder (\Noselect).

Indicates that a folder is remote folder. (\Remote).

This folder is used to hold copies of messages that have been sent (\Sent). Some server implementations might put messages here automatically. Alternatively, this might just be advice that a client save sent messages here.

Indicates that a folder is subscribed. (\Subscribed).

This folder is used to hold messages that have been deleted or marked for deletion (\Trash). In some server implementations, this might be a virtual folder, containing messages from other folders.

The folder has been marked as "uninteresting" by the server; The folder does not contain any additional messages since the last time the folder was selected -or- has a zero RECENT message count. (\Unmarked).
