Is anyone interested in > talking about the technical aspects of such a system? Is there really anything to talk about? I just implemented such a thing using SHA1 hashes. Source code, a database consisting of my address, and a Linux binary are available (volunteers to compile other binaries, provide an FTP server, or add their address(es) are welcome!) It can add and delete addresses, check whether addresses are blocked, and filter a list of addresses from stdin. The database is stored as a text file with the hexadecimal representation of the hashes written one per line [actually, the first 0<=n<=5 digits of the hash are appended to the file name, using multiple files to improve search speed.] -- Paul Foley <mycroft@actrix.gen.nz> --- PGPmail preferred PGP key ID 0x1CA3386D available from keyservers fingerprint = 4A 76 83 D8 99 BC ED 33 C5 02 81 C9 BF 7A 91 E8 ---------------------------------------------------------------------- A father doesn't destroy his children. -- Lt.
