Findings
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.

Fix: Move to -all once you have confirmed all senders are listed.
-
dmarc
DMARC is in monitoring mode (p=none), so spoofed mail is still delivered.
v=DMARC1; p=none; fo=1; rua=mailto:dmarc_rua@emaildefense.proofpoint.com,mailto:dmarc-aggregate@airnz.co.nz; ruf=mailto:dmarc_ruf@emaildefense.proofpoint.com,mailto:dmarc-forensic@airnz.co.nz
Fix: Move to p=quarantine and then p=reject once your reports show only legitimate senders failing.
-
mta sts
No MTA-STS policy, so inbound mail can be downgraded to an unencrypted connection.
Fix: Publish _mta-sts.airnz.co.nz and host a policy at https://mta-sts.airnz.co.nz/.well-known/mta-sts.txt.
-
mx
