  • If it is judged as a virus, it returns an error to the sender without relaying.
  • Mails from the sender IP address corresponding to S25R will be refused the connection once. Then, it will be relayed after receiving again.
    S25R: http://www.gabacho-net.jp/en/anti-spam/anti-spam-system.html
  • We verify SPF, DKIM, DMARC and add "Authentication-Results" header. No rejection based on DMARC will be made.
