Re: grabbing the third line of the body

I have done everything I know to get off this list and nothing works. 
 I am now going to agina ask to be taken off the list since I can not
get off by sending the unsubscribe request to your server.  Effective
tommorrow, I will attach this list to my autoresponder and cause you
as much inconvenience as I am being caused by not being able to get
off the list.  That sounds like fair play to me.

send a message to 

procmail-request(_at_)Informatik(_dot_)RWTH-Aachen(_dot_)DE

with the Subject

archive retrieval best_of_procmail_list.gz

or drop me a note and I can send it too, especially if you want it as
straight MIME (otherwise it comes as uuencoded)

I'm unable to do this.

I've tried all the combination I can think of, but I keep getting the
third line of the header (I guess) not the body.

:0fb
{
        LINE3=`sed -n 3p`

        :0fh
        | formail -I"Subject: $LINE3" 
}       

Any clues?
