Diagnosis notes
- Warning: DNS lookup budget exhausted
This diagnosis stopped sending DNS queries after 150 queries. Checks that needed more lookups report their remaining results as unknown; the domain's records may be unusually large or slow to answer.
All checks
MXCan servers find your inbox?No issues foundPass
Nothing to report.
SPFWho may send as you?SPF uses the ptr mechanismNeeds attention
- Warning: SPF uses the ptr mechanism
The SPF record of _spf.mail.yahoo.com uses ptr. RFC 7208 §5.5 says ptr "SHOULD NOT be used": it is slow, unreliable, and some receivers ignore it. Replace it with ip4/ip6 ranges or an include from your provider.
- Warning: SPF ends in neutral (?all)
"?all" tells receivers to treat mail from unlisted servers as neither pass nor fail, so SPF gives no protection. End the record with "-all" or "~all".
DKIMAre your emails signed?No DKIM key found for the common selectorsNeeds attention
- Warning: No DKIM key found for the common selectors
None of the 47 selectors probed under yahoo.com publish a DKIM key. DNS cannot list selectors, so a key under a custom selector may exist: find the s= value in the DKIM-Signature header of a message you sent and check that selector. If DKIM is not set up, enable it at each service that sends mail for yahoo.com.
- Warning: Some DKIM lookups failed
26 of 47 selector lookups under yahoo.com returned TIMEOUT, so whether those selectors hold a key is unknown. Try again later; if it persists, check the domain's nameservers.
