Has anyone got any operational experience with blocking Port 25 from dialup blocks or instituting a "transparent" proxy system that limits email volume? I will summarize and respect privacy requests regarding information. This looks to be fairly straightfoward to do with NAT/"L4 switch" (I hate that term), such as a Alteon or Foundry. I would like to have something like this in operation by end of Q1 99, but want to minimize or eliminate customer pain. This way anyone running proxies on downstream sites, or dialup farms, would have not excuse to not prevent dialup accounts from sending to relays. Those of you in my .procmailrc need not reply, as I won't see it anyway, as we are completely aware of the legal issues involved and know what we are doing. --- Jeremy Porter, Freeside Communications, Inc. jerry@fc.net PO BOX 80315 Austin, Tx 78708 | 512-458-9810 http://www.fc.net
