While we're on the subject of mail, here's a command I use fairly regularly
to strip the Received: lines out of mail headers. Obviously you can apply
it to all your mailing list archives using the X command, hence freeing
up lots of disk space.
,y/^[ ]*\n/g/^From .*\n(^[a-zA-Z\-]+:.*\n(( | ).*\n)*)+/x/^Received: .*\n(( | ).*\n)*/d
or in other words,
, # select the whole file
y/^[ ]*\n/ # loop over the bits between all the blank lines
g/^From .*\n(^[a-zA-Z\-]+:.*\n(( | ).*\n)*)+/
# ensure the current bit matches this regexp which
# describes a mail header (I think!)
x/^Received: .*\n(( | ).*\n)*/
# loop over Received: header lines, handling continuation
# to subsequent lines
d
# delete
