Reduce SPF DNS lookups

Evaluating SPF for ebay.co.uk takes 11 DNS lookups including nested includes; receivers stop at 10 and fail SPF. No detected sending service accounts for these includes; remove each one you no longer send through: p._spf.ebay.com, c._spf.ebay.com, em6952.ebay.co.uk, eu.khoros-mail.com. Changes: Added include:sendgrid.net for SendGrid. Added include:_spf.salesforce.com for Salesforce. Replaced ~all with -all so mail from servers not listed is rejected.

How to apply it

Sign in where your domain’s DNS is managed. This is often where you bought the domain, such as Cloudflare, GoDaddy or Namecheap.
Find the existing TXT record with that name and replace its value.
Save, then come back and re-check. DNS changes can take up to a few hours to show.

SPFWho may send as you?SPF needs more than 10 DNS lookupsFailing

Fail: SPF needs more than 10 DNS lookups
Evaluating the SPF record for ebay.co.uk needs more than 10 DNS lookups (counting nested includes). Receivers stop at 10 with a permanent error, so SPF fails. Remove unused includes or replace them with IP ranges.
How to fix this
Warning: SPF has no "all" term
Without a closing "all" term, mail from unlisted servers gets a neutral result. End the record with "-all" or "~all".

DKIMAre your emails signed?DKIM key shorter than 2048 bitsNeeds attention

Warning: DKIM key shorter than 2048 bits
s2 (1024-bit) uses an RSA key below 2048 bits. Short keys can be factored and some receivers treat them as weak. Rotate to a 2048-bit key at your sending provider.
Pass: DKIM key published
ebay.co.uk publishes a DKIM key under s1, s2.

AlignmentDoes it match your From?SPF alignment is unknownInfo

Info: SPF alignment is unknown
The SPF record of ebay.co.uk can pass for some senders (those matched before the failing part), but another evaluation path ends in a permanent error (spf.lookups.over-limit). Senders that reach that path fail SPF, so whether your mail aligns through SPF is unknown. Fix the error so every path evaluates.

MTA-STSIs mail to you encrypted?No MTA-STS recordInfo

Info: No MTA-STS record
No MTA-STS record at _mta-sts.ebay.co.uk. MTA-STS (RFC 8461) makes sending servers require TLS and a valid certificate when delivering to you, which blocks downgrade attacks.
How to fix this

TLS-RPTWill you hear about failures?No TLS-RPT recordInfo

Info: No TLS-RPT record
No TLS reporting record at _smtp._tls.ebay.co.uk. TLS-RPT (RFC 8460) tells senders where to send daily reports about failed encrypted deliveries to you.

Publish the MTA-STS recordTXT

Tells sending servers that ebay.co.uk publishes an MTA-STS policy at https://mta-sts.ebay.co.uk/.well-known/mta-sts.txt. Change the id whenever the policy file changes.

Set up a TLS report addressinstruction

Sending servers will report TLS failures when delivering to ebay.co.uk, which you need before enforcing MTA-STS. The address must accept TLS reports; a DMARC report address does not necessarily do so.

Applies to: _smtp._tls.ebay.co.uk

Pick an address that will receive TLS reports: a mailbox you read (for example tls-reports@ebay.co.uk, created first) or a TLS reporting service. 2. Publish a TXT record at _smtp._tls.ebay.co.uk with the value v=TLSRPTv1; rua=mailto:<that address>.
