Spammers very seldom use gmail, yahoo or the like to send their spam. They register their own domain, the have their own mail server. I think that the request to attach a mail account to a phone number is rather: 1) COLLECT THE MAXIMUM OF DATA possible about users ... 98) increase the security for the users 99) prevent the creation of temporary, one time, disposable mailbox Best regards, Olivier > > Thanks & Regards. > > --
