new list format

["Shanker R Swaminathan" <csewhiz@xxxxxxxxxxxxxxxx>]

TO THE LISTADMIN
Why is the format of the message so different now?  The reply to filed now
cointains the address of the original sender, so , whenever i try to reply
from my mailer,  the address of the sender and NOT the list comes in the
recipient  filed. IMHO the older format where we could reply to the list was
better. Any expanations for this new behaviour would be gratefully
appreciated.
