I already added all the CNAME and TXT record to my DNS server. However, the outbound.intercom is the only one did not get authenticated and i have already wait more than 48 hours for it.It is because i am in the dev environment?

​@ORX TravelCan you go and check the CNAME here?https://mxtoolbox.com/CNAMELookup.aspxYou will see right away what is being returned by your domain DNS. You can compare what is expected vs what is being returned.

Hi ​@ORX TravelPaul here from support engineering to help you out 🤝I verified your DKIM records are fine and isolated the issue to the Return-Path (outbound) CNAME not resolving to the expected target.What you need to change:In your DNS provider, edit the CNAME for the outbound/return-path host shown in Intercom (found at Settings → Outbound → Email → Sending → Authenticate domain).Ensure the Host/Name field is exactly the host shown (do not add your domain again if your DNS UI auto-appends it).Set the Value/Target to exactly the target shown in Intercom.If you use Cloudflare, set the record to DNS only (grey cloud).Save, wait a few minutes, then click Recheck DNS in Intercom on the same page.Being in a dev or test workspace doesn’t block domain verification. DNS must be public and accurate; once fixed, verification passes within minutes.
