NSEC3 with extra iterations or salt

DNSSEC · NSEC3 uses 5 iterations and a 4-byte salt. RFC 9276 recommends 0 iterations and no salt: extra iterations cost resolvers CPU and add no real protection, and some validators treat high counts as insecure.

Problems

!

Policy: quarantine

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

#4
!

Single MX host, no backup

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

#12
!

1024-bit DKIM key

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (1024 bits), selector1 (1024 bits). Rotate to a 2048-bit key.

#23
!

Broad IP ranges

SPF · These ranges authorize tens of thousands of addresses or more: ip4:40.92.0.0/15, ip4:52.100.0.0/14. Check that you really own and send from all of them.

#27
!

Not configured

TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
