CA DataMinder can identify emails where the sender is internal or external. How it does this depends on whether the email was captured by an endpoint agent or server agent.
By definition, the sender of an email detected by the Outlook or Notes endpoint agent must be internal. This is because, when the email is sent, CA DataMinder has already associated the sender’s Windows logon credentials with a matching CA DataMinder user account. In effect, it recognizes the sender.
When an email server agent (such as the Exchange or Domino agent) detects an email, they need to determine whether the sender is internal or external. This analysis is handled by a CA DataMinder policy engine (PE).
Specifically, the PE uses these settings in its machine policy to determine which user policy to apply:
Specifies a list of internal email address patterns, such as ‘@unipraxis.co*’. When a PE receives an email for processing, it first compares the sender’s address against the listed address patterns:
If a match is confirmed, the sender is deemed internal. The PE then checks whether the sender’s address matches an existing CA DataMinder user’s address. If it does, the PE applies that user’s policy; if not, the PE applies the Unknown Internal Sender’s policy (see below).
If the sender’s address does not match an internal address pattern, the sender is deemed external and the PE applies the External Sender’s policy.
Policy engines use this setting to apply policy to emails sent within the organization from unrecognized users. It defaults to ‘UnknownInternalSender’; this user account is created automatically when you install a new CMS.
Policy engines use this setting to apply policy to external emails. That is, e mails sent from someone outside the organization. It defaults to ‘ExternalSender’; this user account is created automatically when you install a new CMS.
