More opportunities of the request card: If it would br given an quota for each e-mail domains to send application request card, that is more possibility to stop spanning, because, the spammers want to get connection thosands of users. But if there is already a relationship between 2 address, after can send unlimited e-mails. The request card system can be managed by an administrator also, for each users. There would be an e-mail address, the "entry point" managed the sysadmin, to this address came the requests for licence to sending emils the managed domains. So this entry point would works as a "e-mail firewall". _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
