Pardon the interruption but a quick Q

Hi People
	 
I use Smartlist to maintain a large list for newsletters. However because of
mail forwarding some recipients cannot get off the list automatically and I
cannot figure out how they got the email. 
	 
How can I customise each email with the original recipient in the email so I
can remove them manually?
	 
I presume that I have to add a custom footer in rc.local.s20 as per the FAQ
	 
footer.template file looks like:
	 
If you have trouble unsubscribing automatically
email me here mailto:[email protected] -S trouble unsubcribing $ORG_TO
	 
Then add the following to the rc.local.s20 file
	 
#
# Appending a recipient address to every outgoing mail for unsub problems:
#
:0 fbw
ORG_TO=`formail -cXTo: | head -1`
| sed 's/\$ORG_TO/'"$ORG_TO"/g footer.template >footer.txt
| cat - footer.txt
		 
Again my apologies for the intrusion
