Re: On UUCP <-> ARPA Mail Traffic
"The ARPANET is an operational DoD network and is not intended to
compete with comparable commercial service. Accordingly, before
ARPANET service is provided to any non-U.S. Government activity, it
must be determined that adequate comercial service is not available."
"The ARPANET is intended to be used solely for the conduct of or in
support of official U.S. Government business. ...use of the ARPANET
must not violate any applicable privacy laws." [pg. 12, ARPANET
Directory]
"If it is possible to gain access to the ARPANET from another network
(gateway) ..., it is the respnosibility of that host to provide
software protection which will permit only authorized ARPANET users to
access the network." [pg 18, ARPANET Directory]
The only reason we are able to provide any kind of relaying service AT
ALL is because of a ambiuity of wording in the regulations governing
the use of the ArpaNet. Basically, they say that outside users can
not ORIGINATE traffic on the net, but say nothing about outsiders
getting COPIES of things sent on the net. So, our mail gateway
software implements this policy, with one special case. It works like
this:
*) Mail sent from ARPANET to any of our other networks is passed.
*) Mail sent from any other network to ARPANET is rejected, with
explanation.
*) Mail sent from any other network to a MAIL FORWARDER on our machine
is
DELIVERED, regardless as to where it forwards to. Hence, mailing
to
...!brl-bmd!info-cpm@mit-ai
is rejected, as it asks for explicit routing to ARPANET, where as
...!brl-bmd!info-cpm
is DELIVERED, because we automatically forward mail for that list.
Believe me, I wish this was not so, but we have to play by the rules.
Otherwise... "If corrective action is not taken in a reasonable time,
DCA reserves the right to disconnect the host/terminal from the
network." [pg 14, ARPANET Directory]
If you wish to further discuss this issue, the proper forum is in the
TCP-IP Digest ("The InterNet Digest"). It is fed into NETNEWS as
net.tcp-ip; ArpaNet viewers may request direct mailing by sending a
request to
TCP-IP-REQUEST @ BRL
Letters for publication in the digest should be sent to
TCP-IP @ BRL
Network Liaison and Host Administrator of
BRL-BMD,

PS: Attached is an automatic rejection notice, and a letter on this subject.

I have just got a nasty letter from an automatic mailer telling me I
have been reported for attempting to breach the security system of
ARPAnet. All I did was reply to dave Flystra's note about sending all
new members of the info-cpm list a idots guide to things like being
taken off the list.
I very much resent being accused of trying to break a secure system
when all I did was use the unix mailer's 'r' command.
Yes, Jerry, this junk about routing is getting pernicious. IT MUST BE
STOPPED. Abouyt 30% of my network replies are getting sent back now.
The only simple way out seems to be have ARPA and usenet seperate and
have all of usenet that relays news FORCED to relay mail. System
administrators won't like that, so we will probably need intelligent
mailers, which means everyone has to keep their tables up to date.
Sigh !
