Would something like the following work for the date header?

for msg in *; do
  if b4.py $msg 20080216; then
    rm $msg


datestring = get_dateline() ## FIND DATE HDR AND RETURN THE STRING
yyyymmdd = format2yyyymmdd(datestring)  ## CONVERT TO YYYYMMDD
if yyyymmdd < sys.argv[1]:

In the preceding, would the deletions mess up maildir indices?
