How to unsubscribe?
To unsubscribe from a list, send an email to
listar@linuxfromscratch.org and write unsubscribe
listname as the subject header of the message.
Multiple lists can be unsubscribed at the same time
using one email. This is done by writing some junk as the
subject header, something that isn't a valid command like "hello". Then 
the unsubscribe commands come in the body of the message. The email 
will look like: 
To: listar@linuxfromscratch.org
Subject: hello 
unsubscribe lfs-discuss
unsubscribe lfs-apps
unsubscribe alfs-discuss 
After the email was sent, the Listar program will reply with an  
email requesting a confirmation of the unsubscription
request. After this confirmation email is sent back, Listar will 
send an email again with the message that the user has been unsubscribed 
from the list(s).
