Findings
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
v=spf1 include:au._netblocks.mimecast.com include:mail.zendesk.com include:amazonses.com include:navigacloud.com include:_spf.google.com include:spf.mandrillapp.com ip4:118.127.87.207 ip4:128.242.118.200 ~all
Fix: Move to -all once you have confirmed all senders are listed.
-
mta sts
No MTA-STS policy, so inbound mail can be downgraded to an unencrypted connection.
Fix: Publish _mta-sts.stuff.co.nz and host a policy at https://mta-sts.stuff.co.nz/.well-known/mta-sts.txt.
-
mx
Mail is handled by Mimecast.
10 au-smtp-inbound-1.mimecast.com, 10 au-smtp-inbound-2.mimecast.com
