About Shubham
Shubham Dixit is an independent writer and subject-matter expert based in Gurugram, India who publishes practical, technically detailed articles on email file formats and mailbox conversion procedures. His work appears primarily on his LinkedIn profile.
His topical focus is the practical end of email infrastructure, especially the MBOX format: how to fix a mailbox with a missing or broken header, how to deal with multi-gigabyte MBOX files that overwhelm ordinary tools, how to import MBOX data into newer platforms like Notion Mail, and how to convert Google Vault MBOX exports into usable formats. These are the unglamorous but high-stakes procedures that IT administrators and e-discovery specialists perform every day.
His writing emphasizes reproducible, step-by-step procedures over marketing claims, which is what makes his perspective useful as an external reviewer of technical conversion content.
Why he reviews PCDOTS technical content
Email conversion software is a technically dense topic where small inaccuracies can mislead readers. A claim like “our tool preserves all metadata” means different things in different contexts: RFC 5322 headers, X-MS-Exchange properties, MIME boundaries with embedded attachments, S/MIME signatures, Unicode encodings across legacy code pages. These are distinct concerns and a thorough review checks each one.
PCDOTS engages Shubham as an external technical reviewer to verify the accuracy of articles covering email forensics methodology, file-format internals (PST, OST, MBOX, EML, OLM), and migration procedures. His review identifies factual errors, missing edge cases, and claims that need stronger qualification, before articles publish to readers who will rely on them in real IT, legal, and forensic work.
He is not a PCDOTS employee and his engagement is disclosed on every article he has reviewed (look for the “Reviewed by” byline). The terms of his engagement do not require him to recommend PCDOTS products; his role is strictly technical accuracy review.

How the review process works
For transparency, here is exactly what an “external technical review” involves when Shubham reviews a PCDOTS article.
Draft article shared
The PCDOTS engineering team writes the technical content. Before publication, the draft is shared with Shubham for review with full context: what claims are being made, what audience the article serves, and what edge cases concern us.
Independent technical review
Shubham reviews the article line by line for factual accuracy, identifies missing edge cases, flags claims that need qualification, and verifies that procedural steps actually work in practice. He is not asked to recommend the product.
Revisions and final publication
Engineering addresses every flagged item. The final article publishes with a “Reviewed by Shubham Dixit” byline and a date. If a future revision is significant enough, the article is re-reviewed and the date updated.
