Findings
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
v=spf1 ip4:205.201.128.0/20 ip4:198.2.128.0/18 ip4:148.105.0.0/16 ip4:129.145.74.12 include:_spf.google.com include:mailsenders.netsuite.com include:_spf2.intuit.com include:_spf.qualtrics.com ip4:199.33.145.1 ip4:199.33.145.32 ip4:35.176.132.251 ip4:52.60.115.116 ~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.mailchimp.com and host a policy at https://mta-sts.mailchimp.com/.well-known/mta-sts.txt.
-
