Status Check Page (red error)

The domain and sub-domain on miab is hosted on seems fine, but none of the other domains seem to be registering MTA-STS correctly.

MTA-STS policy is missing: STSFetchResult.NONE

Everything else needed is green.


How long has it been since you set up your MiaB?

People have reported it taking 24-48 hours for this to clear.


For me this has only appeared on domains that use an external DNS server. If that is the case, it is important to make certain that all mail-related records for the domain have been correctly configured on the external DNS server. MiaB Status Checks reports problems only for certain records.

Check the propagation of the text record for _mta-sts.domain.tld
I believe that’s what the status check is looking for.
