Abstract
A message filtering method makes use of a database in which domain names of a network, such as the Internet, are associated with IP addresses, or with geographic locations. Electronic messages are tested for authenticity by comparing domain names and IP addresses for a message being tested with information in the database. If the sender information in the message does not have the same associations as information in the database, the message may be blocked, flagged as spam, or subjected to further filtering.
Claims1
A method comprising:
- determining, by a computing device, sender information for an electronic mail message, wherein the sender information comprises the domain name within the sender's email address and an originating IP address for at least one of the servers transmitting the electronic mail message;
- determining the permitted users of at least one portion of the domain name;
- determining the permitted users of the originating IP address;
- comparing by the computing device the permitted users of the at least one portion of the domain name with the permitted users of the originating IP address;
- and
- providing an indication of likelihood that the mail message constitutes spam based on at least said comparing, wherein the indication indicates a higher likelihood that the mail message constitutes spam if such permitted users do not match.
