v=spf1 ip4:199.101.162.0/25 ip4:108.174.3.0/24 ip4:108.174.6.0/24 ip4:108.174.0.0/24 ip6:2620:109:c00d:104::/64 ip6:2620:109:c006:104::/64 ip6:2620:109:c003:104::/64 ip6:2620:119:50c0:207::/64 ip4:199.101.161.130 mx mx:docusign.net ~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.linkedin.com and host a policy at https://mta-sts.linkedin.com/.well-known/mta-sts.txt.
