Some large (think yahoo, gmail) mailers use server pools. Retries might be sent from a different server, causing a message to be graylisted many times. Personally, I think it'd be ok to use IPs for a type of whitelist after the IP has passed graylisting. After all, once an IP has passed for one domain/sender, wouldn't it pass for all other domain/senders too? However, this adds another level of complexity (a pre- and a passed- gray list, sometimes referred to as a dual key). If this proved to be a good method, a global whitelist service based on the post-key (simply IP address), sort of like RBLSs but RWLs, could be implemented. I don't know if anyone's pursued such a thing or not. Seems feasible to me though. > 2) if I include an ip address in a whitelist, I become a relay for > that ip address because > that ip address bypass ALL other filters? No, because authentication is still required for non-local domains. Spamdyke filters are only bypassed if/when the sender authenticates. > Thanks in advance, > Davide -- -Eric 'shubes' _______________________________________________ spamdyke-users mailing list [email protected] http://www.spamdyke.org/mailman/listinfo/spamdyke-users
