Manage DKIM records

This guide explains how to add or modify a DKIM record in a DNS zone (of a domain name) managed on the Infomaniak Manager.

Type DKIM

The DKIM record type allows for the optimal functioning of your Infomaniak email. DKIM (DomainKeys Identified Mail) is a protocol that signs emails upon sending.

This ensures that the content of emails is not altered during transit and that they indeed come from the domain of their sender. This standard thus prevents spammers from impersonating legitimate entities.

DKIM will fail if it detects that a message has been altered and unauthorized changes have been made to the message's "From" field.

The DKIM standard is enabled for all Infomaniak clients with a Mail Service whose domain name has its DNS zone managed by Infomaniak. All emails sent from Mail or your chosen email software are automatically signed.

DKIM is not available for subdomains.

Modify the DNS zone

Refer to this guide (click here) to know the steps to manage records in a DNS zone.

Add multiple DKIM records

You can have multiple DKIM records on your domain without limitation, unlike DMARC or SPF, as long as your DNS host allows it.

If you use multiple third-party email providers, e.g., the ERP Odoo, it is necessary to add a DKIM for Odoo in addition to Infomaniak's.

Use unique DKIM selectors to avoid conflicts with existing records. !

Verify the DKIM record

The Global Security tool allows you to easily verify and correct certain problematic records.

And when your domain name is managed elsewhere, you will find the DKIM record to add to the DNS zone there.
