The FCC feature of Emacs mail-mode is well known not to work with active
VM folders.  This is because a copy of the sent message is stored in the
file on disk but not in the folder in memory.  When the folder is saved,
the sent message is lost.

Jamie Zawinski (and others) has written code to make mail-do-fcc work with
active VM folders.  This enhancement has not been incorporated into VM.

The main reason that has been given for having not incorporating the FCC
support within VM is that using the FCC feature is bad since it means not
having the correct Message-ID for the sent message.  Using mail-self-blind
instead has been suggested.

However, the Message-ID can be specified in the outgoing e-mail message
before it is given to the mail transport agent.  I just tested this on my
machine.  I suspect it works on any machine using sendmail, and probably
with all other MTAs as well.

In addition, the FCC feature has a great advantage over mail-self-blind
since it does not interfere with biff-type programs and does not require
special use of any auto-archiving feature.

Since the chief disadvantage that the FCC feature has been alleged to have
turns out not to exist, I propose that the code for the
gnus-inews-message-id function be used along with Jamie Zawinski's
enhanced version of mail-do-fcc to provide FCC support for VM.
