First, a few things about an 'urgent' message. This is a list function,
not a server function. If you send an urgent message to a list, it
only goes to the members of that list. If you send it to all lists,
members of more that one list will be sent multiple copies.

Also, urgent messages are not sent to owners or moderators unless they
are also list members. To mail the owners and moderators of a list,
send mail to LISTNAME-owner at ...

That said, the Urgent: <password> header is just that. It must be added
to your message as a header. Unlike Approved:, it can't be a
pseudo-header in an initial body line, It must be a real message
header. How you do this is a function of your MUA (mail client). Mutt
makes it fairly easy to edit a raw message before it is sent and add
headers. With thunderbird, you can go to Tools -> Options -> Advanced
-> Config Editor... and add Urgent to mail.compose.other.header to add
it to the To:, Cc:, etc pulldown list in mail composition.

Other MUAs such as I think MS Outlook and most webmail clients do not
provide a way to do this.
