Thunderbird’s X-Mozilla-Status and X-Mozilla-Status2 flags
Vincent Bernat
Thunderbird stores mails in the mbox format. In addition to
the header lines set by the MUA or by the MTAs in transit, Thunderbird
stores the message status in two headers: X-Mozilla-Status and
X-Mozilla-Status2. These headers are hexadecimal representations of
the message flags.
The content of the following tables are extracted from the source code of Thunderbird 102.
