SPF
PassValid, soft failAnything not on the list is accepted but marked. Google recommends ~all; with DMARC enforced it is as strong as -all.
v=spf1 include:%{i}._ip.%{h}._ehlo.%{d}._spf.vali.email include:_spf.google.com include:_spf.sendergen.com include:mktomail.com include:_spf.mlsend.com ~all
DKIM
Pass3 keys foundSelectors google, hs1, hs2 publish a public key. 2 of them point at a vendor by CNAME.
google._domainkey, hs1._domainkey, hs2._domainkey
DMARC
PassEnforced (p=reject)Failing mail is rejected. This is the finish line.
v=DMARC1; p=reject; pct=100; rua=mailto:dmarc_agg@vali.email,mailto:dmarc_agg@dmarc.250ok.net; ruf=mailto:dmarc_fr@dmarc.250ok.net; fo=1; rf=afrf
MX
Pass4 hostsMore than one receiving server, so a single outage does not bounce mail.

MTA-STS
PassPublishedThe DNS record is present. The policy file at https://mta-sts.<domain>/.well-known/mta-sts.txt cannot be read from a browser, so its mode is not verified here.
v=STSv1; id=G7p1XZqV2M9RdKUyT0aEbnLCfjwH34sQ;
TLS-RPT
PassPublishedTLS failure reports have somewhere to go.
v=TLSRPTv1; rua=mailto:tls-report@vali.email
BIMI
PassPublishedLogo record found and DMARC qualifies. Yahoo shows it from the record; Gmail and Apple Mail also need a VMC or CMC certificate (the a= tag).

2 · Tools visible in DNS
| Layer | Tool | Evidence |
|---|---|---|
| Mailbox | Google Workspace | MX aspmx.l.google.com |
| Marketing | HubSpot | DKIM hs1._domainkey → calm-com.hs01a.dkim.hubspotemail.net |
| Marketing | Marketo | SPF include:mktomail.com |
| DMARC reporting | Valimail | DMARC rua=mailto:…@vali.email |
Only tools that leave a DNS trace appear. A shared DKIM selector is attributed only when its CNAME target names the vendor.
3 · Sender requirements (Google, Yahoo, Microsoft)
| Requirement | Applies to | Status | Note |
|---|---|---|---|
| Authenticate with SPF or DKIM | GoogleYahooMicrosoft | Verified | At least one method is in place. |
| Bulk senders: both SPF and DKIM | GoogleYahoo | Verified | Both are present. |
| Publish a DMARC record (p=none is enough) | GoogleYahooMicrosoft | Verified | Policy is p=reject. |
| From: domain aligns with SPF or DKIM | GoogleYahooMicrosoft | Not checkable here | Needs a real message. The Send-a-Test report will check this. |
| Valid forward and reverse DNS for sending IPs | GoogleYahoo | Not checkable here | Depends on the sending server, not the domain. |
| Encrypt in transit (TLS) | GoogleYahoo | Verified | MTA-STS shows inbound TLS is required; outbound depends on your sending tool. |
| One-click unsubscribe (RFC 8058) for marketing mail | GoogleYahoo | Not checkable here | A message header, not a DNS record. Microsoft recommends it rather than requiring it. |
| Spam complaint rate under 0.1% (0.3% is the hard limit) | GoogleYahoo | Not checkable here | Read it in Google Postmaster Tools and Yahoo Sender Hub. Google’s target is 0.1%; 0.3% is where enforcement starts. |
