Some emails got bounce back when sending to our domain name. What I meant by some is, only a certain number not all of. We use Gmail so I follow the required step by adding all the MX files. Our mail service was back but still having an issue with a small number of incoming mail from clients that bounce back.
Error from outlook
- reply 531 actstitude.com cannot be resolved
Error from Gmail
- DNS Error: 15353578 DNS type ‘mx’ lookup of actstitude.com responded with code NXDOMAIN
Domain name not found: actstitude.com
Netlify site name: https://actstitude.netlify.app/
Step I have tried:
I have tried the DNS lookup and the record matches and I can’t find any problem (first time doing this)
Waiting for the propagation time
Checking mail header and using google admin toolbox
Until now no clue. Any help will be much appreciated.
Attached is the record snapshot
edit: some similar cases but I have no idea what he meant
