A message index record consists of:
|
|
|
|
4 byte marker - matches record offset
|
|
|
|
4 bytes size - size of data after this header
|
|
|
|
2 bytes unknown
|
|
|
|
1 bytes - number of attributes
|
|
|
|
1 byte unknown
|
|
|
|
Each attribute is a 4 byte value with the 1st byte being the tag
|
|
|
|
and the remaing 3 bytes being data. The data is either a direct
|
|
|
|
offset of an offset within the message index that points to the
|
|
|
|
data for the tag.
|
|
|
|
|
|
|
|
Current known tags are:
|
|
|
|
0x02 - a time value
|
|
|
|
0x04 - text offset pointer, the data is the offset after the attribute
|
|
|
|
of a 4 byte pointer to the message text
|
|
|
|
0x05 - offset to truncated subject
|
|
|
|
0x08 - offste to subject
|
|
|
|
0x0D - offset to from
|
|
|
|
0x0E - offset to from addresses
|
|
|
|
0x13 - offset to to name
|
|
|
|
0x45 - offset to to address
|
|
|
|
0x80 - msgId
|

0x84 - direct text offset, direct pointer to message text
