Sorry, I only partially read your first post. I thought there was some reason for using grep, had I read properly I would have said the same as ZB.

or maybe

Code:
awk '/Content-Disposition: attachment/ {print NR}' mbox

You can also use the below mentioned command too..

grep -n "Content-Disposition: attachment" mbox | cut -d":" -f1
