Tip: You can also restrict who can send mail to specific groups. Open the document properties of the group document and go to the Security tab. Uncheck the Use readers list of the document to determine who can send email to this group. This applies to messages sent from a Notes client as well as through SMTP. If a user who is not allowed to tries to send mail addressed to this group, they receive a non-delivery report indicating that the sender is not authorized to send mail to the specified recipient. The following describes how group names are used normally when receiving an SMTP message addressed to a group. A message is addressed to [email protected]. The local part of the address, All_Employees, is the name of a group in my Domino Directory. This group contains a complete list of All Employees at my company. 1. A message is received via SMTP listener and deposited into MAIL.BOX. 2. The router performs a lookup to the $Users view to determine if the recipient is a valid user. 3. The recipient is found to be valid; it contains a group name. 4. The router needs to expand the group to determine who the members are who should receive this message. 5. Recipients field is added to the message, containing the members of the group (now expanded to the contents of the group). Users or spammers attempting to send to any group name defined in your Domino Directory will now receive a delivery failure report, as shown Figure 4-4. The sender of the message will only be informed that the message was rejected for policy reasons.
