Recover 2021-22 DMARC/SPF/DKIM
Budget: ₹1,500 – ₹12,500 INR
Retrieve Historical DMARC, SPF & DKIM Records (2021–2022) for alameda-research.com
I need to reconstruct the exact DMARC, SPF and DKIM DNS records that were live on my domain during the 2021-2022 period. The data will feed a larger forensics and incident-response review, so accuracy down to each policy tag and key is critical.
I do not have any saved zone-file snapshots or console exports to work from. You will therefore need to rely on passive-DNS feeds, historical WHOIS, Internet Archive captures, RiskIQ, SecurityTrails, VirusTotal, Farsight DNSDB or any similar open-source or commercial intelligence platform you are comfortable with. Feel free to combine multiple sources to validate what was truly published at different dates.
Please supply:
• A timeline showing every distinct DMARC, SPF and DKIM change between 1 Jan 2021 and 31 Dec 2022 (UTC), noting the first and last sighting dates for each record.
• The full TXT strings exactly as they appeared.
• A brief explanation of the lookup methods you used so I can defend the findings in a technical report.
CSV or Markdown format is fine for the timeline, and screenshots or raw API responses are welcome as appendices.

Description:
I need assistance from an experienced DNS/Email security researcher.
Task Requirement:
Retrieve historical DMARC and DKIM DNS TXT records for the domain alameda-research.com for the period 2021–2022.
Confirm whether DMARC was active during that time, and if so, which policy (none/quarantine/reject).
Identify active DKIM selectors in 2021–22.
(Optional but helpful) Provide SPF records from the same period.
Important Notes:
Free lookup sites like MXToolbox, Censys, SecurityTrails did not show historical data.
This will likely require access to paid passive DNS datasets (DomainTools, Farsight DNSDB, RiskIQ/PassiveTotal, etc).
I only need legitimate passive DNS history (no penetration testing, no illegal access).
Please provide proof of records (screenshot/export/report).
Deliverables:
Document/report showing DMARC, DKIM (and SPF if possible) records for 2021–22.
Source of data (which dataset was used).
