Messages received from external sources could be determined to be untrusted by spam reduction checks such as the Sender Policy Framework (SPF) protocol.

About this task

Note: All SMTP-inbound Domino edge servers with SPF and/or DKIM enabled must be at 12.0.2 for this feature to work properly.

You can choose to send messages that are deemed to be untrusted as a result of spam reduction checks to the recipient's Junk folder.

Tip: Hard fails are untrusted messages, but if you choose to treat soft fails as untrusted and therefore delivered to the Junk folder, you can enable the following notes.ini on their mail servers: RouterJunkDeliverSoftfail=1

Procedure

1. From the Domino® Administrator, click the Configurationtab and expand the Messaging section.

2. Click Configurations.

3. Select the Configuration Settings document for the mail server or servers you want to administer, and click Edit Configuration.

4. Click Router/SMTP -> Restrictions and Controls -> Delivery Controls.

5. Locate the Deliver to Junk Folder Controlssection.

6. Set the Deliver untrusted messages to the Junk folderfield to Enabled.

7. If you have users or groups for whom you don't want to deliver untrusted messages to the Junk folder, enter their Notes user names or group names in theExceptions for specific recipients field.
