Paper Details

in this new era of digital world, E-Mail is a communication medium and extensively used, fast & cheap way ofmessage transfer over the internet world. After all, mail is not completely safe & reliable medium due to technicallyalternate loopholes in protocols which able to culprits to make mistreat it especially to send spoofed E-Mails which isrecently large scale problem to handle for mail systems now days. E-Mail sender address spoofing is malicious action wherethe origin address are changed and presented as it is coming from expected sender but the real sender is an assaulter. Inthis paper, we present behavior of several mail applications during receiving the sender address spoofed mails. Werecommend sender spoofing analysis algorithm to check sender spoofing in mails through performing comprehensive headerevaluation on mail header fields. We generally focused on four fields like R-SPF, DKIM, DKIM Signature and DMARC.This proposed algorithm checks the valid values of the headers. Any non valid value shows towards unauthorized mails. Wehave also created data values of legitimate and spoofed mails and implemented the evaluations on mail headers for validand invalid values. Our proposed approach and algorithm is capable to detect sender spoofing especially sender spoofedmails.
