How to configure individual DKIM on your domain

How to configure individual DKIM on your domain

What is individual DKIM?
DKIM (DomainKeys Identified Mail) is an authentication system that adds a digital signature to emails sent from your domain. With individual DKIM, each domain uses its own DKIM signature instead of the shared srv.cat DKIM.

This allows you to:
  1. Improve email deliverability
  2. Correctly align DMARC policies
  3. Improve domain reputation
Do I need to do anything?
It depends on how your domain DNS is configured:
   
      If you use cdmon DNS
  1. No action is required
  2. Individual DKIM will be activated automatically
      If you use DNS from another provider
  1. You will need to add a DNS record to activate individual DKIM
  2. If you do not do this, you will continue using srv.cat (less control, lower reputation)
Where can I find the configuration?
You can check the current status and the required value from your cdmon panel:
Path: Hosting management → Email authentication → DKIM


In this section you will be able to:
  1. See whether DKIM is active
  2. Check the required DNS record
  3. Verify whether the configuration is correct
If the record is configured correctly, the fields will be highlighted in green:


If the record is incorrect or has not yet been detected, it will appear in red.


IMPORTANT: To view the records, you must enable the “advanced options” menu.


DKIM configuration (external DNS)
If your domain uses external DNS, you must create the following DNS record:
  1. Type: TXT
  2. Host: cdkim._domainkey.
  3. Value: (available in your cdmon panel, each domain has its own value)

Important
  1. Copy the value exactly as it appears in the panel. Do not add extra quotation marks
  2. Some DNS providers automatically append the domain in the Host field

How to add the DNS record
The steps may vary depending on the DNS provider, but they are generally as follows:
  1. Access your domain DNS management panel
  2. Locate the DNS records section
  3. Add a new TXT record with the indicated data
  4. Save the changes


If you have any questions about configuring the records, we recommend contacting the support team of the external provider managing your DNS.

How is individual DKIM activated?
Once the record has been added:
  1. The system will automatically detect the configuration
  2. Individual DKIM will be activated without requiring any additional actions
You can verify the status from: Hosting management → Email authentication → DKIM

What happens if I do not configure it?
If the record is not added:
  1. The domain will continue using the shared DKIM (srv.cat)
  2. The authentication and reputation improvements associated with individual DKIM will not be applied

Recommendations
  1. Verify that the record has been added correctly
  2. Please note that DNS changes may take a few minutes to propagate
  3. Check the status from the panel before contacting support
