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