Private header names should start with "X-".  Although '_' is OK '-' is
more conventional.  So your example header would be better named
"X-Balsa-Internal-Id:".

The function already exists.  Just call
  smtp_set_header_option (message, "X-Balsa-Internal-Id", Hdr_PROHIBIT);

This would be my preferred solution.  You know for certain which messages are
sent via which header.  If a message will go via the wrong server, just transfer
it to the correct outbox.  Its probably also the easiest to implement in terms
of the way that libbalsa/send.c currently works.
