	You can't scramble all e-mail addresses that appear in the 
messages that are sent out, because then users couldn't reply, 
misconfigured MTAs might reject the messages as spam, etc....  The 
best you can do is to protect the archives, which Mailman does by 

	However, Mailman also usually provides a link to the full mailbox 
with addresses that have not been protected, and that problem is 
addressed at

	From the main web admin page for your list, go to the "Privacy 
options..." page.  Scroll down to the bottom of the page, and make 
sure that the last radio button is set to "Yes".  It has the 
description "Show member addresses so they're not directly 
recognizable  as email addresses?"  If this needs to be corrected, 
then do so and click on the "Submit Your Changes" button.

	If you want something more than what this option provides, you'll 
need to make source code modifications to Mailman in order to obtain 
your desired results.  If you go that direction, we would appreciate 
your contributing those changes back to the project.
