How to analyze sources?

When you view the sources section in the TDMARC tool you will view a list of ESPs sending emails on behalf of your domain. Some will be legitimate and some might be unknown. You should follow the below steps to fully understand your outbound email flow and configure your sources correctly:

  1. The first step is to set up your SPF and DKIM for the legitimate sources you are using to send emails. You can find SPF and DKIM records for your sources online and if they are not available kindly reach out to your vendors and ask them for the above records. Upon receiving them add your SPF record through the Smart SPF section if you have opted for that feature, else place it on your DNS. Add your DKIM records directly into your DNS. Once you have placed the records, wait for some time for the changes to reflect on your DNS.

  2. Now, to verify if you have configured your SPF and DKIM correctly, you can use our email assessment tool and send an email from that source to test it for SPF and DKIM. 

  3. If you observe that even after adding the respective SPF and DKIM records your SPF and DKIM seem to fail. Then you can click on the source and you will be taken to the breakdown of your emails. 


The source will give you the following details:

From Domain: Your sending email address.

IP: IP used to send your mail.

Date: When you sent the email

PTR: Pointer record (PTR for short) provides the domain name associated with an IP address.

Country: From where the mail is sent

Message: Number of messages from the source matching the row details.

Policy applied: DMARC policy applied
DKIM: DKIM result for your from domain

SPF: SPF result for your from domain

Reporter: From what ESP did we receive the report

DKIM result: DKIM result of DKIM domain

DKIM selector: A DKIM selector is part of the DKIM record and it allows publishing multiple DKIM keys on your domain. When creating a DKIM signature for an email, you will need to mention which private key to use. This key is totally bound to a certain selector.
DKIM domain: the domain generating your DKIM key in your envelope address

SPF result:  SPF result of SPF domain

SPF domain: the domain from your Return-path header and envelope address
