message: Bcc Warning
2.7.7 Bcc Warning
-----------------
The ‘Bcc’ header is meant to hide recipients of messages. However, when
encrypted messages are used, the e-mail addresses of all ‘Bcc’-headers
are given away to all recipients without warning, which is a bug. But
now Message got to warn if ‘Bcc’ recipients are found in an encrypted
message when you are just about to send it. If you are sure those ‘Bcc’
addresses are safe to expose, set the ‘mml-secure-safe-bcc-list’
variable, that is a list of e-mail addresses. See
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=18718>.
