A typo list is not yet a threat model
Generating hundreds of similar domain names creates noise. The useful question is which variants exist and show infrastructure that could support impersonation. MX records, address records and sender-authentication configuration can raise the priority of a lookalike domain because they indicate more than a hypothetical spelling.
Prioritize similarity and capability together
A one-character substitution that resolves and has MX records deserves more attention than a distant spelling with no DNS presence. Risk scoring should combine visual or edit-distance similarity with infrastructure evidence instead of presenting every generated string as equally dangerous.
Do not interpret mail-enabled as malicious
A lookalike domain can be registered for an unrelated legitimate organization. Public DNS cannot prove attacker intent. Use the scan as reconnaissance: identify candidates, then review registration context, websites, certificates, observed mail and business relationships before escalating.
Monitor changes, not only the first snapshot
A domain that is parked today can add MX, SPF or a cloned website tomorrow. The long-term value comes from tracking high-risk variants for meaningful infrastructure changes rather than repeatedly generating the same typo list.
