Email plays a vital role in faster communication. Lots of mails are sent to common public with falsified information that appears to be a realistic. It is mandatory to trace the origin of the email and the authors/systems responsible for generating such emails. Representative signatures of email are to be generated using lexical and syntactic based methods. The signature of each email has huge dimensions and is called a vector/pattern. In order to make it convenient for subsequent processing, the huge dimension of the signature is converted into 2-dimensional pattern using Fisher's Linear Discriminant function (FLD).
