Configuring Mail Server

Endpoint DLP Plus has an option to send notifications by email. To send these email, the mail server has to be configured. Mail Server Settings can be configured in two ways:

  • OAuth Authentication
  • Basic Authentication

OAuth Authentication

OAuth is a standard authorization protocol that uses web tokens instead of passwords to allow delegated access to a protected resource. OAuth allows limited access to the users data, that is, the ability to share data for users without disclosing personal information. Therefore, we can choose to configure using OAuth authentication for sending mails from Endpoint DLP Plus server securely.
