Senders List

The Senders List page gives you full control over the email sources detected for a domain through DMARC reports. Access it from the gear menu on the Domain Overview page.

note

The Senders List is only available for domains that have DMARC monitoring set up and are receiving DMARC reports.

How It Works​

As Palisade processes DMARC aggregate reports, it identifies email sources (sending services and IPs) that are sending mail on behalf of your domain. Each source is categorized into one of three statuses.

Pending Sources​

Sources that have been detected but not yet reviewed. Each pending source shows:

  • Source name — the identified sending service or IP
  • 14-day email compliance — pass/fail rates over the last two weeks

For each pending source, you can:

  • Confirm — mark the source as a legitimate, authorized sender
  • Discard — mark the source as unauthorized or irrelevant

Confirmed Sources​

Sources you have confirmed as legitimate senders. These are recognized as authorized and factor into compliance calculations.

Discarded Sources​

Sources you have marked as unauthorized or irrelevant. Discarded sources are hidden from the main view but can be reviewed and restored if needed.

Why Manage Senders​

Reviewing and confirming senders helps you:

  • Identify all legitimate services sending email for your domain
  • Spot unauthorized senders before tightening your DMARC policy
  • Build confidence that moving to quarantine or reject will not block legitimate mail
  • Track which services need SPF or DKIM configuration updates
Review senders before enforcement

This page is a critical stop before tightening your DMARC policy. Any legitimate sending service that is not properly authenticated (passing SPF or DKIM) will have its mail quarantined or rejected once enforcement is active. Review pending sources carefully — a service you do not recognize may still be legitimate (e.g., a CRM, helpdesk, or marketing tool set up by another team).

tip

New senders can appear at any time — for example, when a colleague sets up a new email tool. Check back periodically, especially after organizational changes, to catch new sources before they become a delivery problem.
