SPF for 3dmail.com
3dmail.com publishes an SPF record; it authorises 1 included sender list, and the record ends in -all (hard fail): mail from a server that is not listed should be rejected.
DMARC for 3dmail.com
The DMARC policy for 3dmail.com is p=reject: mail that fails SPF and DKIM alignment is refused outright. It is the strictest setting and the one Gmail and Yahoo now expect from bulk senders.
Why it matters
SPF says which servers may send as 3dmail.com; DKIM signs the messages; DMARC tells receivers what to do when neither checks out and reports back to the owner. Together they decide whether mail from 3dmail.com is trusted, and whether someone else can pretend to be 3dmail.com. For verification they are a domain-quality signal: Spaw folds a missing SPF record into the risk score and reports has_spf and dmarc_policy on every email and domain lookup.
