Note:
You can also use mutt's builtin facilities to get custom
Message-IDs.
# in muttrc
send-hook . "source ./msgid"
# in file "msgid" next to muttrc
# put any command within the backticks
my_hdr Message-ID: <`uuidgen -r`@t-8ch.de>
The extra config file and "source" command are needed to force
reevaluation of the backticks for each message.
This should also work in older versions of mutt and has the advantage
that mutt knows about the actual Message-ID, for example showing it with
edit_headers=yes.
