1024-bit DKIM key

1024-bit RSA keys are the minimum and are considered weak today: selector2 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.

TLS

Found

DANE (TLSA records)

napaonline-com.mail.protection.outlook.com	none	-

Checks

!

Not configured

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.

#32
i

Not configured

TLS-RPT lets senders report TLS delivery problems to you. It is most useful together with MTA-STS or DANE.

#35
i

Not used

No MX host publishes TLSA records. DANE lets senders verify your mail server's certificate through DNSSEC; it requires DNSSEC on the MX host's zone.

BIMI

No BIMI record

Checks

Not configured

BIMI shows your logo next to your mail in supporting mail clients. It requires DMARC enforcement.
