Is anyone considering the fact that there are many users on the ARPAnet that are not "official" users? My opinions: The INFO-THIS, INFO-THAT problem is a site administration problem. Your site allows your users to receive those lists. I'm not sure there are programs to prevent people from getting added, but if somebody were willing to watch the mail logs and "catch" the people, they could be told to conform to site policy and get themselves removed from the lists. One possible solution is to ask all maintainers of major mailing lists to completely disallow individuals on the lists and require that all "recipients" be local redistribution lists at the target sites. This would allow site managers to restrict incoming mail volume by disallowing their users to receive lists contrary to site policy. (Sounds facsist, and it probably is. I don't know if I believe this, but it is a possibility.) The "multiple users receiving the same message on separate connections" problem has two causes. The major cause is that the sending site refuses to send the same message to multiple recipients. I believe this was the case with previous Unix software; I don't know if it has ever been fixed. A second possible cause is lack of local redistribution. "Official DARPA business" made a lot more sense back in the NCP days. With the advent of IP, it can be claimed that you aren't connected to the ARPAnet, you are connected to the Internet. The ARPAnet is logically and physically just a very small part of the entire Internet. The real problem we are seeing is that it is the backbone of the Internet. The solution is obvious (I'm assuming the proliferation of machines will continually increase traffic): put more bandwidth into the >>Internet<<. This could be by adding more ARPAnet capability, or providing other (redundant) paths. Who pays for it isn't clear, nor is the choice of technology. I'm not flaming, I just had an extra 2 cents in my pocket... The 2 cent token is moving around the net...
