Solid base — two policy steps remain.
ahabana.co.cu's DMARC policy could not be resolved on this scan, so its protection against spoofing is unknown.
Your SPF setup is currently using a soft fail at the end, which tells receiving mail servers to be cautious with messages that don’t match your approved senders. This matters because it makes it easier for spoofed or unauthorized email to slip through as “maybe valid” instead of being clearly rejected. The fix is to tighten the SPF policy to a hard fail once you’re sure every legitimate sender is included.
v=spf1 mx a ip4:200.55.178.235 a:mx.ahabana.co.cu ~allYour email authentication is using a DKIM key that is too short, which makes it weaker than recommended. This matters because weaker keys are easier to break, so email spoofing and tampering are harder to defend against. The fix is to replace that DKIM key with a stronger, longer key and update the DKIM setup for the affected selector.
