Abstract:
The present invention includes methods and systems for securely delivering electronic mail to electronic mail servers having dynamic IP addresses. Before requesting mail delivery, a receiving mail server having a dynamic IP address registers its dynamic IP address along with a receiving mail server code in memory accessible by a dynamic name server. The receiving mail server code is preferably also stored with the domain name for which the receiving mail server receives mail in memory accessible by a private name server. In response to a request for mail delivery, a delivering mail server utilizes the receiving mail server code stored in memory accessible by the private name server and the dynamic name server to determine the dynamic IP address.
