Thank you for your assistance. I tried this then:
TEXT=`sed -e1d -eq footer.txt` :0 fbBw * $ ! ()<$\TEXT$ | cat - footer.txt
Works great, but also seems to need at least 2 lines in the footer. Is there a way to make it work for a one line footer?
I am SLOWLY learning how to write shell scripts and procmail recipes, but my knowledge of sed and cat is nil at this point!
