Understanding Split DNS Configuration

What is Split DNS?

Split DNS allows you to use different hosting providers for different services on the same domain. In this case:

• Website hosting: Vercel handles your website
• Email hosting: cPanel handles your email

This works because DNS records serve different purposes:

• A/CNAME records direct web traffic to your website
• MX records direct email traffic to your mail server

Benefits of This Setup

Why use Vercel for websites:

• Lightning-fast global CDN
• Automatic HTTPS and SSL certificates
• Git-based deployment workflow
• Excellent performance for modern web frameworks

Why use cPanel for email:

• Full-featured webmail interface
• Unlimited email accounts
• Spam filtering and security features
• Email forwarding and autoresponders
• Access via IMAP/POP3 for desktop clients

Step-by-Step Setup Guide

Phase 1: Add Domain to cPanel

Even though your domain points to Vercel, you need to add it as an addon domain in cPanel for email management.

Steps:

1. Log in to your cPanel account
2. Navigate to the Domains section
3. Click on Addon Domains
4. Enter your domain details:
   • New Domain Name: yourdomain.com
   • Subdomain: Leave as auto-generated
   • Document Root: Accept default or customize
5. Click Add Domain

Success message: “You have successfully created the new ‘yourdomain.com’ domain”

Important note: Adding a domain to cPanel does NOT change where it points. Your DNS records control actual traffic routing.

Phase 2: Configure DNS Records in Your Domain Registrar

This is where the magic happens. You’ll configure your DNS to split traffic between Vercel and cPanel.

For GoDaddy Users:

1. Log into GoDaddy
2. Go to My Products → Domains
3. Select your domain → Click DNS or Manage DNS
4. Configure the following records:

Required DNS Records

1. A Record (Website – Points to Vercel)

• Type: A
• Name: @
• Value: Your Vercel IP (find this in the Vercel dashboard)
• TTL: 1 Hour

2. CNAME Record (WWW subdomain)

• Type: CNAME
• Name: www
• Value: cname.vercel-dns.com (or your specific Vercel CNAME)
• TTL: 1 Hour

3. A Record (Mail Subdomain – Points to cPanel)

• Type: A
• Name: mail
• Value: Your cPanel server IP (e.g., 142.4.198.208)
• TTL: 1 Hour

4. MX Record (Email Routing)

• Type: MX
• Name: @
• Value: mail.yourdomain.com
• Priority: 0
• TTL: 1 Hour

Critical: Your MX record should point to mail.yourdomain.com (which points to cPanel), NOT to your main domain (which points to Vercel).

Phase 3: Email Authentication Records

These records are essential for email deliverability and preventing your emails from being marked as spam.

Get Your Records from cPanel

1. Log in to cPanel
2. Search for Email Deliverability
3. Click on your domain name
4. You’ll see suggested records for SPF, DKIM, and DMARC

Add SPF Record

What is SPF? Sender Policy Framework tells receiving servers which IPs are authorized to send email for your domain.

In your DNS:

• Type: TXT
• Name: @
• Value: (Copy exactly from cPanel Email Deliverability)
• Example: v=spf1 +mx +a +ip4:51.222.203.80 +include:spf.web-dns1.com
• TTL: 1 Hour

Common mistake: Including the wrong IP address. Always use the exact SPF record from your cPanel.

Add DKIM Record

What is DKIM? DomainKeys Identified Mail adds a digital signature to your emails to authenticate them.

In your DNS:

• Type: TXT
• Name: default._domainkey
• Value: (Copy the long DKIM string from cPanel)
• Example: v=DKIM1; k=rsa; p=MIIBIjANBg... (very long string)
• TTL: 1 Hour

Pro tip: Use the copy button in cPanel to avoid errors. DKIM values are very long and must be exact.

Add DMARC Record (Optional but Recommended)

What is DMARC? Domain-based Message Authentication, Reporting & Conformance defines how to handle emails that fail authentication.

In your DNS:

• Type: TXT
• Name: _dmarc
• Value: v=DMARC1; p=quarantine; adkim=r; aspf=r; rua=mailto:dmarc_rua@onsecureserver.net;
• TTL: 1 Hour

Phase 4: Create Email Accounts

Now that DNS is configured, create your email accounts in cPanel.

Steps:

1. In cPanel, go to Email Accounts
2. Click Create
3. Fill in the details:
   • Username: support (becomes support@yourdomain.com)
   • Password: Create a strong password
   • Storage Space: Set quota or unlimited
4. Click Create

Repeat for additional email accounts (info@, sales@, etc.)

Phase 5: Access Your Webmail

You can access your email in multiple ways:

Option 1: Direct Webmail Access

• URL: https://webmail.yourdomain.com
• Log in with your full email address and password

Option 2: cPanel Webmail

• URL: https://cpanel-domain.com:2096
• Log in with email and password

Option 3: Email Client Configuration

For Outlook, Thunderbird, Apple Mail, or mobile devices:

Incoming Mail Server (IMAP):

• Server: mail.yourdomain.com or srv7.swhc.ca
• Port: 993 (SSL/TLS)
• Username: your full email address
• Password: your email password

Outgoing Mail Server (SMTP):

• Server: mail.yourdomain.com or srv7.swhc.ca
• Port: 465 (SSL) or 587 (TLS)
• Authentication: Required
• Username: your full email address
• Password: your email password

Troubleshooting Common Issues

Issue 1: Cannot Send Emails (Gmail Blocks)

Error message: “Your email has been blocked because the sender is unauthenticated. Gmail requires all senders to authenticate with either SPF or DKIM.”

Solution:

1. Check your SPF record includes the correct sending IP
2. Verify the DKIM record matches exactly what cPanel shows
3. Common problem: Email sends from IP 68.168.119.164 But SPF only lists 51.222.203.80

Fix: Update SPF to include all sending IPs from cPanel’s Email Deliverability section.

Issue 2: Cannot Receive Emails

Checklist:

• MX record points to mail.yourdomain.com (not the main domain)
• mail.yourdomain.com has an A record pointing to the cPanel IP
• Priority is set to 0
• The domain is added as an addon domain in cPanel
• The email account exists in cPanel

Issue 3: Emails Go to Spam

Solutions:

• Ensure SPF record is correct and includes all sending IPs
• Verify DKIM is properly configured and matches cPanel
• Add a DMARC record with an appropriate policy
• Check your domain reputation (use tools like MXToolbox)
• Avoid spam trigger words in subject lines

Issue 4: DNS Changes Not Working

Wait for propagation: DNS changes can take 1-48 hours to fully propagate globally, though usually it’s much faster with a 1-hour TTL.

Check propagation status:

• Use whatsmydns.net to check global DNS propagation
• Use MXToolbox.com to verify MX records
• Use the dig or nslookup commands

Test DNS:

# Check MX record
dig MX yourdomain.com

# Check A record for mail subdomain
dig A mail.yourdomain.com

# Check SPF record
dig TXT yourdomain.com

MX	@	mail.yourdomain.com	0	Email routing
TXT	@	SPF record	–	Email authentication
TXT	default._domainkey	DKIM key	–	Email signature
TXT	_dmarc	DMARC policy	–	Email policy

Security Best Practices

Email Security

1. Use strong passwords for all email accounts (16+ characters, mixed case, numbers, symbols)
2. Enable two-factor authentication in cPanel if available
3. Regularly update passwords every 90 days
4. Monitor for suspicious activity in cPanel email logs
5. Configure spam filters in the cPanel Email Filters section

DNS Security

1. Enable DNSSEC if your registrar supports it
2. Use reputable DNS providers for better reliability
3. Regularly audit DNS records to ensure no unauthorized changes
4. Lock your domain at the registrar level to prevent transfers

Email Client Security

1. Always use SSL/TLS connections (ports 993, 465, 587)
2. Never use plain text authentication (port 110, 143)
3. Keep email clients updated to the latest versions
4. Be cautious with email attachments and links

Frequently Asked Questions

Can I use any domain registrar?

Yes! This setup works with any registrar (GoDaddy, Namecheap, Cloudflare, Google Domains, etc.). The DNS configuration process is similar across all registrars.

Do I need to change nameservers?

No! You keep your registrar’s nameservers and just update individual DNS records. This gives you flexibility and control.

Will my website go down during setup?

No. You can configure everything first, then switch DNS records. There may be a brief propagation time, but no significant downtime.

Can I use a different email provider instead of cPanel?

Absolutely! This same method works with:

• Google Workspace (formerly G Suite)
• Microsoft 365
• Zoho Mail
• Any email hosting with MX records

Just point MX records to your email provider instead of cPanel.

How long does DNS propagation take?

With a 1-hour TTL, changes typically propagate within 1-2 hours. The maximum is usually 24-48 hours globally. Most users see changes within minutes.

Can I have multiple domains?

Yes! Repeat this process for each domain. In cPanel, add each as an addon domain. In DNS, configure records for each domain separately.

What if my cPanel and Vercel are on different accounts?

That’s fine! This setup is designed for exactly that scenario. They operate independently through DNS routing.

Is this setup secure?

Yes, when properly configured. Both Vercel and cPanel provide SSL/TLS encryption. Follow security best practices outlined in this guide.
