Mailman headers and email clients

[gaf at blu.org (Jerry Feldman)]

Mailman inserts several header items into each outgoing email message, which appear below. 
Some email programs, like exmh, add buttons to the reader panel, Pegasus 4.01(Windoz) adds a 
button on the reader window when clicked results in a popup with buttons to subscribe, 
unsibscribe, help and contact list admin. Eudora, instead of adding buttons, it inserts those as 
clickable links at the top of the reader window. I would like to know how other email programs on 
Linux handle this,
