fix_mbox_from.py
Utility for fixing incorrect 'From' line after batch .EML files import
via Thunderbird's ImportExportTools version LE 2.3.2.1.
2010-05-01 bug report sent to addon author.
mailbox.py (Python 2.4.5) pattern for matching 'From' line:
_fromlinepattern = r"From \s*[^\s]+\s+\w\w\w\s+\w\w\w\s+\d?\d\s+" \
r"\d?\d:\d\d(:\d\d)?(\s+[^\s]+)?\s+\d\d\d\d\s*$"
Correct 'From':
From - Tue Apr 27 19:42:22 2010
Broken 'From':
From - Sat May 01 2010 15:07:31 GMT+0400 (Russian Daylight Time)
