DKIM (DomainKeys Identified Mail) is a protocol used for the authentication of sent emails and as such preventing them from being misclassified as spam. DKIM records are added to the DNS settings of your domain. We advise using both SPF and DKIM for your identities in Congressus Manager.
Note: you can only setup DKIM for domain names you control yourself and which are known by Congressus.
Setting up DKIM for your domain
In order to set up your DKIM records you need access to your DNS. The records to implement can be found by navigating to Settings > Identities and editing a known identity. The second tab shows the available DKIM records if enabled.
Navigate to Settings > Identities
Click on edit for the identity you want to use DKIM
Click on the tab 'DKIM <yourdomainname>'
Check the box to enable DKIM
Press 'Save changes'
When enabled, Congressus Manager shows the DKIM records to be added to your DNS. In order to do this:
Navigate to the DNS settings of your domain name
Add the DNS records
Check if the DNS records are added correctly
Double-check the settings
After setting up your DKIM-records, we automatically check the correctness of these settings. Once the DKIM has been set up correctly, DKIM is used for the authentication of all mailing sent from Congressus Manager.
You can also check whether the DNS records are correctly added yourself. You can do this by clicking the link 'Check' next to every DNS record at your DKIM settings.
Attention: if there is more than 24 hours between you activating DKIM and actually adding the DNS records, it can happen that the DKIM setting will not be recognized. In that case, uncheck the DKIM check box in Congressus Manager, save changes, and check the box again.
Next to DKIM we also advise adding SPF records. You can read more about this in this article about SPF records.
