The imcheck -m mailbox command displays metadata that describes the entire mailbox and metadata that describes each message.
The message-specific data is displayed in a table. Most of the fields in the table are self-explanatory. However, the following fields need further explanation:
Message type ID, defined by configutil parameters such as store.messagetype.* and store.messagetype.enable. For a list of these parameters, see configutil Parameters.
System flags. The system flags are as follows:
Recent Deleted Seen Answered Flagged Draft Archived
In the imcheck -m mailbox output, the system-flag metadata is displayed as a list of zeros and ones. A one (1) means a particular flag is set; a zero (0) means the flag is not set. The list of zeros and ones corresponds to the flags shown in the preceding list, in the order shown above. For example:
indicates that the Seen flag has been set, and no other flags are set.
Flags defined by the user. User-flags are displayed as a hex number. The binary form of the hex number represents the user-flag switches. For example, if the user has defined six flags, the value
indicates that all six flags are set.
