Domain Verification

Verification process

After adding DNS records, Venmail checks each record type:

Record	Status	Meaning
SPF	OK	SPF TXT record includes Venmail
DKIM	OK	DKIM public key published correctly
Return Path	OK	CNAME pointing to Venmail return path
MX	OK	MX records configured (receiving only)

Checking via dashboard

1. Go to Settings > Domains
2. Click on your domain
3. Click Verify DNS
4. Review the status of each record

Checking via API

curl -X POST https://m.venmail.io/api/v1/domains/check \
  -H "X-Server-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "id": 1 }'

Common issues

SPF not detected

• Ensure the TXT record is on the root domain, not a subdomain
• Include include:spf.venmail.io (not just the IP)
• Check for conflicting SPF records (only one SPF record per domain)

DKIM not detected

• The selector must match exactly (usually venmail._domainkey)
• The full public key must be in a single TXT record
• Some DNS providers split long TXT records — ensure it’s joined

Return path not resolving

• CNAME must point to rp.venmail.io (not an IP)
• Check the subdomain matches what Venmail expects (usually rp.yourdomain.com)

MX not detected

• MX records must be on the root domain
• Priority values (10, 20) must be present
• Both mx1.venmail.io and mx2.venmail.io should be configured
