+The purpose of this patch is to alter the behavior of the write_bcc option
+because exim4, the default SMTP in Debian, does not strip the Bcc headers; by
+default write_bcc is set so this could cause a privacy leak.
+
+The behavior that this patch introduces is: never write the Bcc header when the
+message is sent, otherwise, if the message is sent to Fcc, then this optin
+will be evaluated and the Bcc header will be written based on that.
+
+Background discussion on this is in the following bugs:
+http://bugs.debian.org/304718
+http://bugs.debian.org/467432
+
+This patch is a slightly modified version of the patch provided by
+Stefan Völkel <stefan@bc-bd.org> in the second bug
