Abstract
Phishing is detected by creating a message transfer agent (MTA) map, with each point on the MTA map referencing an MTA. Points on the MTA map are connected based on a number of emails with same signature sent by MTAs represented on the MTA map. Reference MTA groups are identified from the map. Phishing is detected when an MTA sent an email with the same signature as that of emails sent by MTAs belonging to a reference MTA group but the MTA is not a member of the reference MTA group.
