Problems

!

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: selector2 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.

#23
!

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.
