DNS Zone in lightsail not shown in DNCHECKER

The issue you're experiencing with your DNS records for EVREEL.COM, particularly the CNAME records not showing up in DNS checkers, could be due to a few factors:

1. Propagation Time: DNS changes can take up to 48 hours to fully propagate across the internet. However, with Lightsail's default TTL (Time to Live) of 300 seconds for DNS records, you should typically see changes much sooner.

2. CNAME Record Configuration: Ensure that your CNAME records are correctly configured in your Lightsail DNS zone. Double-check for any typos or formatting errors.

3. Lightsail DNS Limitations: Lightsail DNS has some limitations, particularly with records containing underscores. If your CNAME records include underscores, this could be preventing them from being accepted or propagated correctly.

4. DNS Checker Tool: Some DNS checking tools may not query all record types by default. Make sure you're specifically requesting CNAME records in your DNS lookup.

5. Conflicting Records: Ensure there are no conflicting records in your DNS zone that could be interfering with the CNAME records.

For your email issue (554 5.7.1 SPF Incorrect), this suggests a problem with your SPF (Sender Policy Framework) record, which is typically a TXT record. If you've recently updated this, allow time for propagation and double-check its syntax.

To troubleshoot:

1. Verify all DNS records in your Lightsail console.
2. Use multiple DNS lookup tools to check your records.
3. If issues persist after 48 hours, consider contacting AWS support.
4. For critical DNS needs, you might consider using Amazon Route 53 for more advanced DNS management capabilities.

Remember, DNS issues can be complex and may require patience as changes propagate through the system.
