Can colderove.com be spoofed?

colderove.com publishes DMARC with p=none — spoofed mail is monitored but not blocked.

WarningSPF

Finding 01

SPF ends in '~all' (softfail) rather than '-all' — acceptable for DMARC (non-pass either way); hardening to '-all' is optional and only safe once every legitimate sender is in the record

WarningDMARCDMARC is recorded but p=none (monitoring only — no protection)
Start monitoring colderove.com →
- no enforcement record is recommended yet — a scan alone could not confirm that your mail aligns (valid SPF and a DKIM signature), and moving off p=none without that evidence risks silently blocking legitimate mail. Gather aggregate-report evidence first, then step up: evidence before enforcement
- p=none only monitors — it does not block spoofing
- no np= tag: non-existent subdomains fall back to sp/p — RFC 9989 §4.7's np=reject can protect them now
Current DMARC
v=DMARC1; p=none; rua=mailto:[email protected]
