-b option is not working

[Erwan Prioul]

I sent an email using the -b option to add a bcc address.

$ mail -b <email address hidden> <email address hidden>
Subject: a subject
bla bla bla
bla bla bla
.
EOT

It sent the email to <email address hidden> but it sent nothing to <email address hidden>.
It's like the -b option is ignored.

This bug was fixed in the package bsd-mailx - 8.1.2-0.20160123cvs-3

---------------
bsd-mailx (8.1.2-0.20160123cvs-3) unstable; urgency=medium

  * Make the `-b' option work again: update 03-Base-fixes-2.patch to revert
    the `comment out bcc code' change introduced in 1:8.1.1-10.2. The change
    is no longer needed after upstream switched to using the `-t' option
    of sendmail in 8.1.2-0.20150408cvs-1 (closes: #823412, LP: #1576641).
    Many thanks to Frederic Bonnard for finding the cause of the issue.
  * debian/control:
    + refer to s-nail package in the description instead of transitional
      heirloom-mailx (closes: #775766);
    + drop ancient Breaks/Replaces;
    + switch Vcs-Browser to cgit, and Vcs-Git to https;
    + bump Standards-Version to 3.9.8.
