<a href="http://www.faqs.org/rfcs/rfc2822.html">RFC
2822</a> defines the <tt>Sender</tt> header and defines it
as "the mailbox of the agent responsible for the actual
transmission of the message." Mailman replaces this header
by default with the list's bounce address.

<p>While it is debatable if Mailman is such an agent, setting
this header helps directing bounces from some broken MTAs to
the right destination. On the other hand, some mail
readers show unexpected behaviour if this header is set (like
missing addresses in forwarded mails and copies sent to the
bounce address on reply-to-all), so it can be disabled
here.
