Why DNS Verification Is Important

Correctly configured DNS records are essential for:
  • Email delivery: Ensures your emails reach their destination
  • Sender reputation: Helps prevent your emails from being marked as spam
  • Security: Protects your domain from email spoofing and phishing attacks

​
What Records to Verify

Before using any verification tools, understand what you’re looking for:

​
1. MX Records

Verify that your MX record points to mail.a101.bot with priority 10: 
yourdomain.com. IN MX 10 mail.a101.bot.

​
2. SPF Records

Verify your SPF record is correctly formatted and includes the A1Mail server: 
mail.yourdomain.com. IN TXT "v=spf1 ip4:110.232.112.135 a:mail.a101.bot ~all"

​
3. DKIM Records

Verify your DKIM record exists and contains the public key provided by A1Mail: 
2025_default_mail._domainkey.mail.yourdomain.com. IN TXT "v=DKIM1; h=sha256; k=rsa; t=y; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA..."

​
4. DMARC Records

Verify your DMARC record is correctly formatted: 
_dmarc.yourdomain.com. IN TXT "v=DMARC1; p=none; rua=mailto:[email protected]"

​
Verification Tools

​
Shortcuts:

​
1. Command Line Tools

You can use command line tools like dig or nslookup to verify your DNS records: 
# Check MX records
dig MX yourdomain.com

# Check TXT records (for SPF, DKIM, DMARC)
dig TXT mail.yourdomain.com
dig TXT _dmarc.yourdomain.com
dig TXT 2025_default_mail._domainkey.mail.yourdomain.com

​
2. MxToolbox

MxToolbox provides comprehensive DNS checking tools:
  • For MX records: Use the MX Lookup tool
    • Enter: mail.yourdomain.com
  • For SPF records: Use the SPF Record Lookup tool
    • Enter: mail.yourdomain.com (exact host)
  • For DKIM records: Use the DKIM Lookup tool
    • Enter: subdomain._domainkey.yourdomain.com (You can find this in the A1Mail email dashboard)
  • For DMARC records: Use the DMARC Lookup tool
    • Enter: _dmarc.yourdomain.com (exact host)

​
Troubleshooting Common Issues

​
DNS Propagation Delays

DNS changes can take up to 48 hours to propagate worldwide. If your verification fails initially, wait a few hours and try again.

​
Incorrect Record Format

Ensure there are no typos or formatting errors in your DNS records. Even small errors can cause verification to fail.

​
Missing Records

Verify that all required records (MX, SPF, DKIM, DMARC) are present. Missing any one of these can affect email deliverability.

​
Cloudflare Proxy Enabled

If using Cloudflare, ensure the proxy (orange cloud) is disabled for all email-related DNS records. Email requires direct DNS resolution.
