So Joe User turns the clock back a year on his PC, to get around an

message, timestamped as it leaves his pop client with some goofy date.
Your script, as written, will dutifully extract the date header, parse
it, and spool to the wrong directory, because you relied on bad data.
This is a reason why MHonArc (by default) keys off the Received header
for the date of the message. Pre-processing scripts may want
to the same.
