Sender and Receiver Addresses as Cues for Anti-Spam Filtering
Chih‐Chien Wang · 2008
This study analysed the sender and receiver addresses of 3,417 unsolicited e-mails. Over 60.3 % of unsolicited e-mails were found to have an invalid sender address and 92.8 % receiver addresses did not appear in the “To ” or “CC ” headers. The analytical results indicated that e-mail addresses in the header could provide a cue for filtering junk e-mails.
