With deep expertise in internet security and resilient infrastructure, the Valimail team regularly contributes to standards and threat detection communities — driving today’s email authentication policies and tomorrow’s cybersecurity advancements.
We have a corporate commitment to lifting up the messaging industry as a whole and working collaboratively with partners throughout the ecosystem to restore trust to email.
We participate in several organizations working to make a difference.
We write and maintain open source code used by the largest mailbox providers (like Oath/Yahoo!) and make our contributions available to all, fixing issues in an accessible, scalable, global way.
We contribute to the protocols that continue to advance email and make it better for everyone.

Written by Valimail, the ARC Test Suite is an informal schema for the open source test suites for the Authenticated Received Chain(ARC) protocol, illustrated with examples.
OpenARC is a community effort to develop and maintain an open source library for producing ARC-aware applications, and a "milter"-based filter for providing ARC service. Valimail has contributed, tested, and managed the completion of this project.
Valimail contributed code that supports ARC within Mail::DKIM, which implements the various components of the DKIM and DomainKeys message-signing and verifying standards for Internet mail.
dkimpy is a Python module that implements DKIM (DomainKeys Identified Mail) email signing and verification. It also provides helper scripts for command line signing and verification. Valimail contributions support ARC functionality and bug fixes as the standard evolves.
Valimail built the Mailman ARC patch, which provides ARC functionality for Mailman 3. Mailman is one of the most widely deployed mailing list management software in the world.
Valimail maintains OpenDMARC and contributes code to support the evaluation and reporting of ARC. OpenDMARC is a community effort to develop and maintain an open source package for providing DMARC report generation and policy enforcement services.
OpenDKIM is maintained by Valimail. We contribute code to support the evaluation and reporting of ARC to this TDP software that supports 100's of millions of mailboxes.
Valimail wrote this password policy enforcement extension for devise-gem, which is a flexible authentication solution for Rails based on Warden.
