Findings
-
spf
SPF ends in ~all (softfail); unauthorised mail is marked rather than rejected.
v=spf1 ip4:111.91.135.0/27 ip4:125.209.208.0/20 ip4:125.209.224.0/19 ip4:210.89.163.112 ip4:210.89.173.104/29 ip4:114.111.35.0/24 ip4:61.247.196.0/24 ip4:61.247.197.0/24 ~all
Fix: Move to -all once you have confirmed all senders are listed.
-
dmarc
DMARC is in monitoring mode (p=none), so spoofed mail is still delivered.
v=DMARC1; p=none; rua=mailto:dmarc_reports@worksmobile.com
Fix: Move to p=quarantine and then p=reject once your reports show only legitimate senders failing.
-
dkim
No DKIM key found at any common selector. Either DKIM is not configured, or it uses a custom selector we cannot discover from DNS alone.
Fix: Enable DKIM signing at your mail provider and publish the selector they give you.
-
mta sts
No MTA-STS policy, so inbound mail can be downgraded to an unencrypted connection.
Fix: Publish _mta-sts.naver.com and host a policy at https://mta-sts.naver.com/.well-known/mta-sts.txt.
-
mx
4 mail exchangers published.
10 mx1.mail.naver.com, 20 mx5.mail.naver.com, 20 mx4.mail.naver.com, 20 mx6.mail.naver.com
