Signed response to an abusive email account owner and provider systems and methods

摘要

Systems and methods for abusive email account detection and transmission of a signed response to an abusive email account owner and provider. The methods include receiving an email from a first email account on a second email account, wherein the email contains malicious content, determining if a trust relationship exists between a first email server corresponding to the first email account and a second email server corresponding to the second email account, and transmitting, using a hardware processor of the second email server, an alert email to the first email account corresponding to the trust relationship, wherein the alert email includes a digital signature and a secure field having an abusive category descriptor in an email header. The secure field may include an abusive category descriptor, for example transmitting spam, transmitting malware, transmitting phishing attempts, and committing fraud.
