Introduction
DomainKeys Identified Mail (DKIM) is a widely used email authentication protocol that helps prevent email spoofing by allowing recipients to verify the legitimacy of an email sender. Configuring DKIM for Pepipost ensures that your outgoing emails are signed digitally, reducing the chances of being marked as spam and improving email deliverability.
In this guide, we will walk you through the process of generating and configuring DKIM for Pepipost, verifying your setup, and troubleshooting common issues.
What is DKIM?
DKIM is an email authentication method that uses a cryptographic signature to validate email messages. When an email is sent, it is signed with a private key, and the receiving mail server can verify the authenticity using the corresponding public key published in the sender’s DNS records.
Benefits of DKIM Authentication
Prevents Email Spoofing – Ensures that emails sent from your domain are legitimate.
Improves Email Deliverability – Reduces the chances of your emails being marked as spam.
Enhances Domain Reputation – Authenticated emails boost your sender reputation.
Works with DMARC – Complements SPF and DMARC policies to improve security.
How to Generate DKIM for Pepipost
Step 1: Log into Your Pepipost Account
Visit the Pepipost website and sign in to your account.
Navigate to the Settings or Domain Authentication section.
Step 2: Generate Your DKIM Key
In the authentication settings, find the DKIM Configuration section.
Click on Generate DKIM Key for your domain.
Pepipost will generate a unique public/private key pair.
Step 3: Create a DKIM Record in Your DNS
Once you have the DKIM key, you need to publish it in your domain’s DNS records.
DNS TXT Record Details
Name: pepipost._domainkey.mydomain.com
Type: TXT
Value: k=rsa; p=MIGf…..[use the unique DKIM key generated by Pepipost for your domain]
Replace mydomain.com with your actual domain name.
Step 4: Add the DKIM Record to Your DNS
Log into your DNS provider (GoDaddy, Cloudflare, Namecheap, etc.).
Navigate to the DNS Management section.
Click Add New Record and select TXT Record.
Enter the details as provided by Pepipost.
Save the record and wait for DNS propagation (this can take a few hours to 48 hours).
Step 5: Verify DKIM Setup in Pepipost
Return to your Pepipost account.
Go to Domain Authentication.
Click on Verify DKIM.
If successful, your domain will show a Verified status.
Best Practices for DKIM Configuration
1. Use 2048-bit Key Strength
If Pepipost allows, generate a 2048-bit key instead of 1024-bit for better security.
2. Rotate DKIM Keys Periodically
Changing your DKIM key every 6 to 12 months minimizes security risks.
3. Enable SPF and DMARC Alongside DKIM
For complete email authentication, configure SPF (Sender Policy Framework) and DMARC (Domain-based Message Authentication, Reporting & Conformance).
Troubleshooting DKIM Issues
1. DKIM Record Not Found
Check if the record has been added correctly.
Wait for DNS propagation (up to 48 hours).
2. DKIM Verification Fails
Ensure there are no typos in the record.
Use a DKIM record lookup tool to verify.
3. Emails Still Going to Spam
Ensure SPF and DMARC are correctly configured.
Maintain a clean email-sending reputation.
