Managing user validation/authentication options
After defining your domain groups, you can determine recipient validation and user authentication settings for users in the user directories you create. See Managing domain and IP address groups. User validation and authentication settings are configured on the page .
The following types of user validation/authentication are available:
- Recipient validation, in which a message recipient is validated before a message is received.
- SMTP authentication, in which a message sender is authenticated before a message is received.
- Personal Email authentication, in which a user is authenticated before accessing the Personal Email Manager facility for managing blocked email. See Configuring Personal Email Manager End User Options.
- Distribution list validation, in which individual members of an email distribution list are validated. If an individual recipient in the group is invalid, the message is rejected just for that individual. All valid recipients in the distribution list receive the message.
Include group email addresses in your user directories to use the distribution list validation option. A message to an invalid group alias is rejected for the entire group of recipients.
Users in a domain group are verified against the corresponding user directory, and specified authentication settings are applied.
You may create multiple Personal Email Manager user authentication groups. However, any protected domain group (as defined in ) may be included in only one Personal Email Manager user authentication group.
Including a protected domain group in more than one Personal Email Manager user authentication group may result in the users of that domain group being denied access to the Personal Email Manager facility.
Add all the user directories that contain the users in this protected domain group to the associated Personal Email Manager authentication group.
The User Authentication List displays the configured user authentication settings. The Add and Delete buttons are used to add or remove recipient validation and authentication settings.
