It seems that there are many technical means to stop abuse from the resource usage sense: 1. Prevent non-members from sending mail to the list. (This may be done already, but since I don't know, I cannot say.) 2. Limit the rate of new subscription requests (perhaps on a per- host or per-domain basis.) 3. Re-order out-going mail (from toad.com) according to size. Drop messages from queue if it gets "reordered" too many times. 4. Truncating long messages. 5. Re-order out-going mail (from toad.com) according to time of last mail (from the originator). Basically, limit the rate of mail from any particular person or host or domain. 6. Refuse connections from "known host(s) or domain(s) of abusers" during "busy" periods. These are not whole-sale censorship mechanisms, but just abuse- resistence measures. Ern
