How to add a DKIM field to a domain name

Procédure

DKIM makes it possible to sign emails sent from your domain name. This signature helps mail services verify that your messages are [PERSON_NAME] and that they have not been altered during sending.

In the LWS Panel, the DKIM record is normally added automatically when your domain name is registered with LWS, uses LWS DNS and uses the mail service included in your plan. A manual correction may however be necessary if the record has been deleted, if it is missing, or if the domain’s DNS zone is managed by another provider.

Before you begin

Before adding or correcting DKIM, check where your domain name’s DNS is managed.

If your domain uses [ADDRESS] DNS, you can add the DKIM record from the LWS DNS Zone.

If your domain uses external DNS, you must copy the DKIM values shown in the LWS Panel and send them to the service provider who manages your domain’s DNS zone.

Understanding the DKIM alert

In your domain’s email administration, the LWS Panel displays a block called Mail status. [ADDRESS] lets you check the important elements for sending emails, including:

• SPF;
• DKIM;
• DMARC.

If a problem is detected, an orange icon appears. [PERSON_NAME], [PERSON_NAME] is [PERSON_NAME] or has not yet been correctly taken into account.

Click the DKIM link to display an information window. It contains the values to add to the domain’s DNS zone.

Retrieve the DKIM values to add

From the LWS Panel, open the email address administration for your domain.

In the Mail status block, click DKIM.

A window opens with the DKIM information to use. You will find:

• a DKIM key: dkim._domainkey;
• a value, starting with v=DKIM1; k=rsa; p=....

Copy these two pieces of information without modifying them.

Add the DKIM record if the DNS is with LWS

If your domain name uses [ADDRESS] DNS, add the record in the domain’s DNS Zone.

To do this, follow the dedicated documentation

When adding the DNS entry, choose the TXT type, [PERSON_NAME]

• in the Name field: the DKIM key shown in the window: dkim._domainkey;
• in the Value field: the full DKIM value shown in the window.

Then validate the addition of the record.

If the DNS is managed outside LWS

If your domain uses external DNS servers, do not modify the LWS DNS Zone.

You must send the DNS provider managing your DNS the information shown in the DKIM window:

• the record type: TXT;
• the DKIM key;
• the full DKIM value.

The provider or external DNS service will need to add this record in your domain’s active DNS zone.

Check that DKIM is correctly taken into account

After adding the TXT record, [PERSON_NAME], while DNS propagation takes place. It may not be taken into account immediately.

Then return to your domain’s email administration, [PERSON_NAME] Mail status.

Common issues

[PERSON_NAME] DKIM alert

If no DKIM alert appears in the Mail status block, no action is needed. The DKIM record is already being detected correctly.

I added the DKIM record, but the alert is still displayed

Wait for DNS propagation, then check again. If the alert remains displayed, [PERSON_NAME]

• the record added is indeed of type TXT;
• the DKIM key exactly matches the one shown in the LWS Panel;
• the DKIM value has been copied in full;
• the record was added in the DNS zone actually used by the domain.

My domain uses external DNS

In this case, the addition must be done with the provider managing the domain’s DNS. [ADDRESS] LWS DNS will not be taken into account as long as the domain’s DNS servers are not [PERSON_NAME]>

I deleted the DKIM record by mistake

If the DNS is managed by LWS, retrieve the key and value again from the DKIM link in the Mail status block, [PERSON_NAME] the LWS DNS Zone.

If the DNS is external, send this information to the DNS provider so that they can recreate the entry.
