Ok, I need help here. Specially from email server admins that can see their
logs or understand this behavior :-D

What I did:
# Install postfix (and mutt) in KTD:
  $ apt install postfix mutt # it removed exim4
# Add a line to /etc/postfix/main.cf
  $ echo "header_checks = regexp:/etc/postfix/header_checks" >>
/etc/postfix/main.cf
# Add a header_checks file:
  $ echo '/.*:/     WARN' > /etc/postfix/header_checks
  $ postmap /etc/postfix/header_checks
# Restart postfix
  $ service postfix restart
# Watch the logs on a terminal:
  $ tail -f /var/log/mail.*

With that setup, I noticed we needed bug 28017 so we can check things without
emails failing because of (say) Gmail policy validations.

I generated a 'koha' user in KTD:
  $ adduser koha

Then set things so my user has a check-in notice, and set its address to
kohadev-koha at localhost

Set KohaAdminEmailAddress to root at localhost
Set NoticeBcc to koha at localhost

Then run:
   $ kshell
  k$ misc/cronjobs/process_message_queue.pl -v

=> SUCCESS: The logs show:

So the Bcc header is there. I'm not sure why it isn't sending the email
afterwards. But I'm sure the header is correctly added.

Note: the non-advertised feature of accepting comma separated addresses is
still not working. I can solve it on a separate bug report if someone files it.
It needs to specify which fields could be multi-address.
