Can garvan.org.au be spoofed?

garvan.org.au publishes DMARC with p=none — spoofed mail is monitored but not blocked.

WarningSPF

Start here

SPF ends in '?all' (neutral — failing mail is treated no differently) 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

AI explanation

Your SPF setup ends with a neutral policy, which means mail that doesn’t match the listed senders is not clearly rejected. This matters because it gives weaker protection against spoofed email, though it is still acceptable for DMARC checks. If you want to tighten it, the change is to switch to a stricter “fail” policy only after you’ve confirmed every legitimate sending service is included.

Current SPF

v=spf1 include:spf.protection.

WarningDMARCDMARC is published but p=none (monitoring only, no protection)
Start monitoring garvan.org.au →
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
AI explanation
DMARC is set up, but it is only in monitoring mode, so it is not actually stopping forged emails that pretend to be from your domain. This matters because scammers can more easily spoof your address, which can hurt trust and increase phishing risk. The fix is to change DMARC from monitoring to an enforcement policy so mail that fails authentication is rejected or quarantined.
