That will not happen as we have gone beyond this stage. Email is too free and independent to be curbed like that. But a valid 'estamp' type technique could at least ensure that those mails are not dropped or bounced.
Any other method to solve the problem of mail delivery failures? :)
Someone has already suggested Yahoo DomainKeys which identifies legitimate mail servers. http://antispam.yahoo.com/domainkeys
Its going through the IETF standardisation process and any email service provider can implement it.
