Restricting users from sending Internet mail
You can control the transfer of outbound mail from your organization to the Internet.
About this task
Domino® provides two methods for restricting outbound Internet mail:
- Outbound sender controls - These controls specify which users in your organization are allowed to send mail to the Internet.
- Outbound recipient controls - These controls specify the Internet destinations to which users can send mail.
Setting outbound sender controls
About this task
The outbound sender controls let you specify who can and cannot send mail to the Internet. The controls are implemented in two sets of Allow and Deny lists:
- Internet addresses of users who can or cannot send mail to the Internet
- Notes® addresses of users who can or cannot send mail to the Internet
Domino sends a restriction failure message to restricted users who attempt to send outbound mail. You can customize the text of mail failure messages.
The Outbound sender controls are not intended to restrict SMTP relay access. To configure relay restrictions, use the Inbound Relay Controls on the tab of the Configuration Settings document.
Procedure
What to do next
This outbound sender controls are not intended to control relaying. For information on using Domino's inbound relay controls, see the related topics.
Setting outbound recipient controls
About this task
The Outbound recipient controls let you specify the Internet domains, and host names users are allowed to and denied from sending mail to. The controls consist of a set of pair of lists, one specifying the Internet domains or host names to which users can send mail and another listing the domains and host names to which users cannot send mail.
Procedure
Results
For security reasons, if there is a conflict between the two fields for a given setting, entries in the Deny field take precedence. For example, if renovations.com appears in both the Allow messages only to recipients in the following Internet domains or host names field and the corresponding Deny messages field, Domino denies messages sent to renovations.com. Be careful not to have the same entry in an Allow field and a Deny field for the same setting.
Domino checks each address to see if it is an Internet address or a Notes address. The Router then applies the restrictions specified for that type of address.
If you are entering multiple names in a field, consider creating a group and entering the group name in the field. Domino expands the group into a list of members. If you update the group list in this document or edit the group members in the Domino Directory, changes do not take effect immediately.
