Sending status reports to developers@ in BCC is not possible anymore.
Configuration now requires developers@ to be included in To: or CC:
headers.
The reports are still sent to freebsd-announce@, freebsd-hackers@,
freebsd-stable@, freebsd-current@, and are also available on the FreeBSD
website. Thus, all developers can very easily access status reports even
if no e-mail is sent to developers@.
Then, stop sending reports to developers@ mailing list.
