If the invitation is rejected, then the inviter is added to the invitee’s blacklist, which prevents the inviter from contacting the invitee again.

In most deployed email systems, messages cannot be reliably authenticated. However, secure email services, IM, VoIP services, and social networking sites can authenticate content.
