It's been done for years. For example in online form filling out, when the web server sends an email to the claimed address, with a URL link in the email (with an embedded cookie) that once clicked tells the server that the form is being filled out by someone at that address. Or what some humans do when their credit card company calls them, and they say "I'll call you back at the number on the card". Or what SPF or uRPF do, in a passive way. _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
