Publish a valid _dmarc TXT record so Lumail can verify DMARC on your sending domain.
You got is missing DMARC or DMARC record is malformed. Receiving servers have no usable policy for the From domain.
Lumail does not create this record for you.
| Type | Host | Value |
|---|---|---|
| TXT | _dmarc | v=DMARC1; p=none; rua=mailto:[email protected] |
Use your own mailbox for rua= if you want aggregate reports. rua= is optional.
p=none is a valid starting policy. Lumail will then open DMARC policy is monitoring only until you move to quarantine or reject. That is expected — see How to strengthen DMARC.
The TXT must:
v=DMARC1p=none, p=quarantine, or p=rejectTypical breaks: a CNAME on _dmarc, two TXT records, p= missing, or a typo like v=DMARC.
If you send from news.example.com and _dmarc.news.example.com is empty, Lumail uses _dmarc.example.com. Publishing DMARC only on the root is enough. Publish a subdomain record only when that subdomain needs a different policy.
