5 years ago When parsing an mbox file, the Python mailbox library is confused by the presence of lines starting with 'From' in the body of the text. A new fragmentary message item is created, but this is wrong. The following sample code and input demonstrates this. Replacing 'From' in the message body with, say, ' From' results in correct parsing.
This defect prevents correct import of mbox files into hyperkitty for GNU Mailman 3, as one instance where this is an impediment, as the message items become corrupt.
-- Python code import sys import mailbox
def main():
print('mailbox read test')
mbox = mailbox.mbox(sys.argv[1])
for msg in mbox:
print('~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~')
print(msg)
print('~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~')
if __name__ == "__main__":
main()--- sample mbox with one message
