Sender Identification (or Sender ID, or SID) refers to the origin of an email message. Sender ID is a protocol that validates the origin of email messages by verifying the IP address of the sender against the alleged owner of the sending domain.
By monitoring and authenticating Sender IDs, users can ensure that their emails are being sent by authorized senders and are not being spoofed/manipulated by malicious actors. The authorized senders will also allow organizations to list their senders easily.
Our goal is to create a seamless experience and opportunity to manage, and configure domains and their SPF & DKIM records by their sending source, as well as see the reports based on SIDs.
Sender Identification provides an easy way to manage DMARC policies and receive DMARC aggregate reports in a better and more detailed way. With the new feature, users will be able not only to see well-classified aggregate reports but also to monitor and configure them properly.
Note: The configuration (gear) button is not clickable when all domains are selected. You will need to select one domain from the drop-down filter, then click on the button to see the Sender Source Configuration pop-up. An identical pop-up (Sender Source Information) is available when you click on the Sender Source logo or name.
Once verified by PowerDMARC, each sender source will provide detailed information about the email-sending provider with its valid logo, name, description, and even instructions on how to configure the SPF and DKIM protocols. You can see the sender sources grouped and displayed accordingly in Aggregate reports > Per sending source page.
For each sender source displayed in the Aggregate Reports, the user can see the Actions column with the Edit/Label and Configuration (gear) button (active once the domain is selected).
- Labeling the Sender Source gives an opportunity to label Validated and Not Validated Sender Sources. You can add your custom name for SS, then add a comment and enable the “Authorize Sender Source” toggle if you trust Sender Source.
Once authorized and saved you will see the updated Sender Source on the Per sending source page with the green icon next to the Sender Source name.
Note: If you want to revert changes, just click the edit SS again, remove the label, and save the changes. The default name will be displayed for that Sender Source.
Sender Source Configuration for SPF & DKIM
In order to see the sender sources, their detailed information, and configuration links, please click on the Configuration (gear) button, or the Sender Source Logo/Name.
The buttons will open the Sender Source Configuration and Sender Source Information pop-ups accordingly. Both pages provide detailed information about the Sender Source, as well as the links to configure SPF and DKIM protocols for the selected source.
- If the protocols are properly set up for a selected domain, both SPF and DKIM sections will have ”Configured” status.
- SPF mechanisms for validated Sender Sources
Each validated Sender Source will have the SPF mechanism displayed on the Configuration page. The user can copy the record and add it either in the DNS or apply for Hosted Services and add the value directly in the PowerSPF page. Once added, the next aggregate report will be SPF Passed with the “Configured” status shown in the pop-up.
- Automatic/Hosted configuration of SPF and DKIM protocols
If you have enabled Hosted Services like PowerSPF and Hosted DKIM in our platform, you can click the Go to PowerSPF or Go to Hosted DKIM buttons and get redirected to the appropriate pages where you can configure your records.
- Manual configuration using SPF and DKIM References
After clicking on the Configuration gear button, or directly on the Sender Source name or logo, you can find the references to the instructions on how to manually configure SPF and DKIM protocols for that Sender Source. After clicking on the links you will be redirected to the Sender Source’s website where you can find official instructions.
The Top 5 Sender Sources and Top 5 Threats/Unknown/Unaligned Sources tables display the sender sources, their volumes, and the top IPs with highest volume of the sent emails. It will make it more productive for the user to monitor the sender sources for added domains, as well as identify the risks for them.
