How to Set Up DKIM for Alibaba Cloud? | A Step-by-Step Guide with Visuals
Step 1 – Generating DKIM Keys
You must first generate DKIM keys to set up DKIM for Alibaba Cloud. Follow these steps to get this done.
Log in to Alibaba Cloud
Access your Alibaba Cloud account by logging in at Alibaba Cloud Console.
Navigate to the Email Service
Go to the “Products and Services” section and select “DirectMail” under the “Domains & Websites” category.
Access DKIM Settings
In the DirectMail service console, find and click on the “Domains” tab. Here, you will see a list of your domains.
Select a Domain
Select the domain you wish to configure DKIM for and click on its name to access its settings.
Generate DKIM Keys
In the domain settings, look for the DKIM section. Click on “Generate DKIM Keys.” Alibaba Cloud will generate a private-public key pair for your domain.
Step 2 – Adding the DKIM Public Key to Your DNS
Copy the Public Key
Once the keys are generated, you will see the public key provided by Alibaba Cloud. Copy this key to add it to your DNS records. Yes, it’s mandatory!
Access Your DNS Settings
Go to your DNS provider’s website and log in to your account. If you use Alibaba Cloud DNS, navigate to the “DNS” section in the Alibaba Cloud Console.
Add a New TXT Record
In the DNS settings for your domain, add a new TXT record. The details you need to enter are:
Host/Name
This is usually something like default._domainkey – but verify with the exact name provided by Alibaba Cloud.
Type
TXT
Value
Paste the public key you copied earlier.
Save the DNS Record
Save the new TXT record. DNS propagation can take up to 48 hours, so allow some time for the changes to take effect.
Step 3 – Verifying DKIM Setup
Wait for DNS Propagation
Before verifying, wait for DNS changes to propagate. This process can take from a few minutes up to 48 hours.
Verify DKIM in Alibaba Cloud
Go back to the DirectMail service in the Alibaba Cloud Console. In the DKIM section of your domain settings, click on the “Verify” button. Alibaba Cloud will check if the public key is correctly added to your DNS records.
Check Verification Status
If the DKIM setup is correct, you will see a success message. If there are issues, double-check your DNS settings to ensure the public key is correctly entered.
Step 4 – Testing DKIM
Send a Test Email
Send an email from your domain to a recipient you can monitor (e.g., your email address on a different service).
Check Email Headers
Once the email is received, view its headers. How you do this depends on the email client you are using. Look for the “DKIM-Signature” header. This indicates that the email was signed with DKIM.
Use Online Tools
There are various online tools available to check DKIM signatures. One popular tool is DKIMValidator. Send an email to the address provided by the tool, and it will analyze the DKIM signature for you.
Step 5 – Monitoring & Maintenance
Regular Monitoring
Regularly monitor your DKIM setup to ensure it remains functional. Changes to DNS or email configurations can affect DKIM.
Rotate DKIM Keys
For enhanced security, consider rotating your DKIM keys periodically. This involves generating new keys and updating your DNS records accordingly.
Monitor Email Deliverability
Keep an eye on your email deliverability rates. If you notice a sudden drop, verify that your DKIM setup is intact.
Troubleshooting Tips for Alibaba Cloud DKIM
DNS Propagation Delays
If verification fails, it might be due to DNS propagation delays. Wait a while and retry.
Incorrect DNS Entries
Double-check the host/name and value fields in your DNS settings. This process is so sensitive that even typing errors can lead to issues.
Conflicts with Other DNS Records
Ensure that the DKIM TXT record does not conflict with other DNS records for your domain.
Conclusion
DKIM is crucial for email security. Setting up DKIM for Alibaba Cloud is a thoughtful step toward the growth of your business.
