[0013] An email trust service is described. In an embodiment, an email message is received at an email distribution service for distribution to client devices corresponding to recipients of the email message. Authentication techniques may be applied to email messages to verify that the email message was received from an authorized domain as specified in the sender address field of the email message. The authentication technology may include a domain key identified mail (DKIM) authentication technology or a SenderID (sender ID) authentication technology. Authenticating an email message using DKIM or SenderID can be used to determine whether the email message was received from a sender authorized to send email messages from authorized domains.

Abstract

In embodiments of an email trust service, an email message is received at an email distribution service for distribution to a client device that corresponds to a recipient of the email message. Authentication techniques can be applied to verify that the email message is received from an authorized domain as specified in a sender address field of the email message. Additionally, it can be determined whether an Extended Validation certificate is associated with the authorized domain. Responsive to determining that an Extended Validation certificate is associated with the authorized domain, a trust indicator is associated with the email message to generate a trusted email message. The trust indicator indicates that the trusted email message is from an authorized domain when the email message is displayed at the client device.

Background technique [0001] Phishing and spoofing attacks attempt to gain sensitive information from email recipients by sending email messages that appear to come from a trusted source, such as a well-known company or financial institution. Accordingly, when responding to or interacting with email messages, email recipients must take care to ensure that sensitive information, such as bank account numbers, usernames, and passwords, is not transmitted to untrusted sources. As a result, some email recipients unwittingly transmit sensitive information to untrusted sources attempting to solicit personal information, while others simply ignore receiving it out of fear that personal information may be obtained and used against them Email messages from legitimate sources. Contents of the invention [0002] This Summary is provided to introduce a simplified concept of an email trust service, which is further described below in the detailed description. This Summary is not intended...
