Thanks. Search for details on Bayesian filtering and Judea Pearl, as one suggestion. There was a Risks Digest article a while back that should both be relevent here, and easily available. For one take on best-practices, take a look at: ftp://ftp.isi.edu/in-notes/rfc2505.txt The spammers have seen this stuff and are working to avoid it. As an alternative to DELIVER, there is a PIPE_MAILSHR utility and the Majordomo server for OpenVMS. To acquire a kit, send a mail message to the SMTP address majordomo@lassie.ucx.lkg.dec.com, no subject line, and include the following commands in the body of the message: get vms-majordomo-users PIPE_MAILSHR_ECO1_ZIP.UUENCODED get vms-majordomo-users VMS_MAJORDOMO_FT6_ZIP.UUENCODED PIPE_MAILSHR passes messages into the DCL PIPE command for processing. This stuff should be on the next Freeware distribution, for those that wish to wait for it... ---------------------------- #include ----------------------------- For additional, please see the OpenVMS FAQ -- www.openvms.compaq.com --------------------------- pure personal opinion --------------------------- Hoff (Stephen) Hoffman OpenVMS Engineering hoff[at]hp.com
