Findings
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
v=spf1 include:squarespace-mail.com include:mail.zendesk.com include:_spf.google.com include:sendgrid-spf.email.squarespace.com include:registrarmail.net include:_spf.mailrelay.rrpproxy.net ip4:8.41.221.0/24 ip4:8.36.86.0/24 ip4:34.174.163.32/27 ip4:162.216.148.0/27 ~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.squarespace.com and host a policy at https://mta-sts.squarespace.com/.well-known/mta-sts.txt.
-
mx
