Findings
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
v=spf1 include:mg-spf.greenhouse.io include:_spf.google.com include:mail.zendesk.com include:emailus.freshservice.com include:_spf.salesforce.com ip4:4.7.16.128/26 ip4:38.108.186.0/24 ~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.klaviyo.com and host a policy at https://mta-sts.klaviyo.com/.well-known/mta-sts.txt.
-
mx
