I have been hacking on the NOS mailbox recently. Paul Healy, EI9GL,
wrote some good forwarding code for NOS. I started changing Pauls code,
and I am not sure if he will recognize it now.

The NOS mailbox now supports forwarding, both outgoing forwarding and
reverse forwarding. It keeps track of which bulletins have been
forwarded by adding "X-Forwarded-To:" lines to the messages. Messages
in public "areas" are sent as bulletins, with BID and everything.
Messages from private areas are treated as private mail and are
deleted after forwarding.

The message areas can be checked for messages to forward at a regular
intervals, which is set with the "mbox timer" command.
Forwarding can be started immediately with the "mbox kick" command.
There is also a "mbox motd" and a "mbox attended" command, which I
picked from the G1EMM code.
There is a new command in the mailbox too, "Verbose." It displays a
message with all it header lines, contrary to "Read" which only shows
four lines. It is also possible to read a message simply by typing its
number.

The mailbox reads a forwarding file, "spool/forward.bbs". Here is a
sample file:

sk0tm 0006
ax25 ax0 sk0tm
sk0tm
amsat
all
------
sm0rgv
netrom #sth675
..c sm0rgv-2
sm0rgv
amsat

The first word on the first line in a forwarding record is the name of
the BBS to forward to. This should be the same type of name which is
shown by the "mbox status" command. The second word is optional. It
specifies a range when forwarding may take place. "0006" means that
there will only be forwarding to this station between midnight and 6am.

The second line specifies how to establish the connection. It should
start with the protocol (ax25, tcp or netrom) and be followed by all
the parameters which are necessary when NOS has to establish a network
connection.

Directly after the second line there may be lines that start with a
dot. What follows after the dot will be sent to the remote BBS as soon
as the connection is established.

Then follows the names of a number of message areas, public or
private. Finally, there should be a couple of '-' signs to separate
one forwarding record from another.

The code seems to be working, although there could of course be bugs
left. Anyway, the source is available with ftp from sics.se. The
filename is archive/packet/ka9q/nos/mailbox.arc.

As usual, this message is the only documentation, so it could be worth
saving.

The latest version of mailbox.arc at sics.se dated October 12, 14:36,
contains some bug fixes, not only to the forwarding code but to the
general message handling mechanism as well.

Now there is support for what people call "hierarchical routing
designators."
The mailbox now understands its own "*** LINKED to" message...

It is possible to specify several time intervals in the forward.bbs
file. For instance: "w0xxx 0006,1212" means that there may be
forwarding to w0xxx whenever the forwarding timer expires from midnight
until 7 am, and from noon until 1 pm.

By the way, some time ago I wrote a short file called rwhodump.c that
displays received RWHO packets on screen. There are lots of RWHO
traffic on our Ethernet that would otherwise be displayed as garbage.
One could make NOS send RWHO packets of its own too, indicating who are
logged in to the mailbox, but I am not sure if it would be really
useful... Anyway, I have put this file at the sics.se FTP directory as
well.
