Details of change
New Signature:
Signature name: MBOX
Signature Description: Based on https://www.rfc-editor.org/rfc/rfc4155, BOF: ASCII string 'From ' , followed by a {1-255} wildcard in place of a sender identifier or system message, followed by a ctime-format timestamp comprising an English-language three-character weekday abbreviation (Mon|Tue|Wed|Thu|Fri|Sat|Sun), three-character month abbreviation (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec), day-of-month digit, and time in HH:MM:SS format.
Note that this identification pattern has been tested with Gmail and Thunderbird-produced MBOX files and should suit all MBOX files produced following the established UNIX pattern described here: http://qmail.org./man/man5/mbox.html however there may be other variants that differ in implementation.
Binary Signature, BOF, Offset 0: 46726F6D20{1-255}(4D6F6E|547565|576564|546875|467269|536174|53756E)20{0-2}(4A616E|466562|4D6172|417072|4D6179|4A756E|4A756C|417567|536570|4F6374|4E6F76|446563)20{0-2}[30:39]20[30:32][30:39]3A[30:35][30:39]3A[30:35][30:39]
New Prioities: fmt/720 will require priority over fmt/950 - MIME Email, since valid mbox files will often also conform to the fmt/950 identification signature.
