This page describes a possible DNS-only review for discussion. If separately quoted and accepted in writing, it could examine public DNS records for one named email domain and report the observations, their limits and possible next steps. This is not an offer, booking, or promise that the service is available.
A quoted review could record public MX, SPF and DMARC answers for the named domain. DKIM can be considered only for selectors identified by the customer or found in the separately agreed scope; public DNS alone does not reliably reveal every selector or sender.
A draft report could show the lookup time, observed answers, methods, limitations and follow-up questions. DNS answers can vary by resolver, cache and time; observations would not prove that every sending service is authorized or that a message will reach an inbox.
If the format is included in the accepted quote, a report could organize observations, risks to verify, suggested owners and validation steps. Recommendations would not authorize configuration changes; implementation or monitoring would require separate written scope and approval.
No mailbox, M365 tenant, message, internet header, or private DNS-zone access; no credential collection; no DNS or mail configuration changes; no comprehensive sender discovery; no guarantee of deliverability, authentication outcomes or policy correctness; and no continuous monitoring, remediation, incident response or cryptographic DKIM signature validation. Do not send credentials, raw DNS exports or diagnostic evidence by email. If a future engagement is accepted, agree the evidence channel and exact data needed in writing first.
No. The concept is limited to public DNS answers. It does not read mailboxes, messages or headers.
No changes are included or authorized by this concept. Any implementation must have its own written scope and explicit approval from an authorized domain owner.
No fee or schedule is stated here. If the service owner confirms availability, a written quote would specify the proposed scope, fee, evidence handling, report format and delivery date. Work starts only after both parties accept it.
Use the form to identify the service and share only high-level context. Do not include credentials, raw DNS exports, mailbox data or diagnostic evidence; agree a suitable channel and the minimum evidence required before sharing anything.
