How to Add a DMARC Record on Infomaniak

Introduction

DMARC tells mailbox providers how to handle mail that fails SPF or DKIM and where to send aggregate reports. For systeme.io email, authentication includes three CNAME records + one DMARC record. Help article 3943 explains adding DMARC in the Infomaniak DNS zone with policy p=none.

Infomaniak’s DNS UI often exposes a dedicated DMARC record type (not only generic TXT). This guide follows article 3943. For all records together, see authenticate your domain on Infomaniak (3942).

How to add a DMARC record on Infomaniak for systeme.io

Prerequisites

  • Domain with DNS zone managed in Infomaniak.
  • Authentication started in systeme.io Settings → Emails (DMARC value in popup / eye icon).
  • Infomaniak account login.

Typical systeme.io DMARC Value

v=DMARC1; p=none; rua=mailto:youraddress@yourdomain.com

  • p=none — monitoring ( How to Create a DMARC Record, 2241).
  • rua=mailto:… — replace placeholder email with an address you monitor (or a reporting service).

In Infomaniak, this string goes in the Target field; Source is _dmarc.

Step-by-Step on Infomaniak (Article 3943)

  1. Log in to the Infomaniak dashboard.
  2. Open your domain → DNS settings (DNS zone).
  3. Click Add a record.
  4. Record type: select DMARC (article 3943).
  5. Source: enter _dmarc (value under Name in the systeme.io popup).
  6. Target: paste the full DMARC string from systeme.io; customize rua=mailto:.
  7. Click Save.

Example:

  • Source: _dmarc
  • Target: v=DMARC1; p=none; rua=mailto:hello@yourdomain.com

Alternative: If your zone editor only offers TXT, add TXT with Source/Name _dmarc and the same string as Target/Value (equivalent to DMARC at the DNS level).

Infomaniak-Specific Notes

  • Mail Service DMARC: Infomaniak also offers DMARC via Global Security for mail hosted with them—that path is separate from publishing records for systeme.io sending; use the DNS zone for systeme.io auth values.
  • One policy: Avoid duplicate _dmarc entries (DMARC + TXT) with conflicting targets.
  • CNAME auth: Add three systeme.io CNAMEs first with exact Target strings (trailing dot when required)—see 3942.
  • Funnel domain: Custom domain CNAMEs ( connect Infomaniak domain, 3944) differ from email-auth records.

Verify DMARC and Domain Status

  1. Allow DNS propagation (minutes to 48 hours).
  2. Run a DMARC lookup on your domain.
  3. In systeme.io Settings → Emails, confirm Verified when CNAMEs + DMARC are correct.
  4. Confirm your sender email address and review email headers.

Troubleshooting

Issue Fix
No DMARC type in UI Use TXT record, Source _dmarc, same Target value.
systeme.io Pending Complete three CNAMEs (3942) + DMARC.
Duplicate DMARC Delete extra _dmarc rows.
CNAME fails validation Re-copy Target with trailing dot from systeme.io.
No aggregate reports Fix rua=mailto to a valid mailbox.
