Technical notes, security disclosures, and architectural overviews from the team building Orvion Mail Core.
How Orvion automatically trims mailbox history to the newest incoming messages and permanently expunges inactive temporary mailboxes after 30 days without lingering telemetry.
A deep-dive into our threat model. By permanently removing outbound SMTP capabilities, we eliminate abuse, protect IP reputation, and focus entirely on high-speed delivery.
An inside look at our HTML sanitation pipeline. We intercept 1x1 image beacons, remove invasive tracking parameters, and allow readers to preview message content safely.
The technical mechanism behind TXT ownership challenges, MX priority routing, and keeping customer domains strictly private from public directory listings.
Orvion is built upon standard internet protocols: RFC 5321 (SMTP), RFC 5322 (Internet Message Format), and RFC 7208 (SPF). We believe email privacy is best achieved through minimalism, zero telemetry, and rigorous lifecycle cleanup.
