Gmail treats labels as folders for the purposes of IMAP.<\/p>\n

As such, labels can be modified using the standard IMAP commands, CreateFolder, RenameFolder, and DeleteFolder<\/a>, that act on folders.<\/p>\n

System labels, which are labels created by Gmail, are reserved and prefixed by “[Gmail]” or “[GoogleMail]” in the list of labels.<\/p>\n

Use the XLIST command to get the entire list of labels for a mailbox<\/a>.<\/p>\n

The labels for a given message may be retrieved by using the X-GM-LABELS attribute with the FETCH command.<\/p>\n
