Historic DMARC & DKIM Retrieval
Budget: ₹1,500 – ₹12,500 INR
I’m building a forensic timeline for www.alameda-research.com and need its complete DMARC and DKIM TXT history from 1 Jan 2021 through 31 Dec 2022. I don’t have direct access to the big passive-DNS stores, so you will have to pull the data yourself from DomainTools, Farsight DNSDB, and RiskIQ PassiveTotal (or any comparable archive you already subscribe to).
The job is straightforward: query those datasets, extract every unique DMARC and DKIM record that appeared during the stated window, and return the raw values along with the first-seen and last-seen timestamps. Accuracy is more important than speed, but a quick turnaround is appreciated.
Deliverables
• CSV (or TSV) containing: record_type, txt_value, first_seen, last_seen, data_source
• Short methodology note describing the exact tools and query filters used
• Optional screenshots or raw query logs that back up each record (helps me verify faster)
I will cross-check a sample of the results in DNSDB; once they line up, I’ll release payment. If you already mine historic DNS every day, this should be a quick win for both of us.

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).
