I’m building a forensic timeline for [login to view URL] 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 [login to view URL] 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).

I specialize in DNS and email security research, with hands-on experience parsing passive DNS data for DMARC, DKIM, and SPF analysis. For your project, I can provide a structured CSV showing record values with first-seen/last-seen timestamps, plus a clear methodology note. Once you supply access or raw exports from DNSDB, PassiveTotal, or DomainTools, I’ll ensure the data is cleaned, verified, and aligned with your forensic timeline needs.

As a member of Iterative Tech, a highly skilled software development company, my expertise lies in data analysis and data processing. These skills would be of immense value to the "Historic DMARC & DKIM Retrieval" project for alameda-research.com. We are experienced in working with diverse datasets, ensuring accuracy and providing efficient turnarounds. Our knowledge goes beyond reliance on free lookup sites which were unable to produce the historical DNS data you need - instead, we have direct access to paid passive DNS datasets including DomainTools, Farsight DNSDB, and RiskIQ/PassiveTotal. This makes it easier for us to handle your task within controlled legal boundaries while still producing the desired results in terms of proof and format. To ensure transparency and accountability, we promise to provide a detailed methodology note outlining the precise tools and query filters we deploy. Additionally, you would receive the deliverables as required - a CSV (or TSV) file containing all the essential record details (record_type,txt_value,first_seen,last_seen along with data_source). And if necessary, we'll also provide screenshots or raw query logs that back up each record. Partnering with us guarantees a seamless project execution from start to finish. Thanks Prem Golani
