Valimail Industry Leadership
Our commitment to restoring email trust.
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.

ARC test suiteWritten 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 examplesOpenARCOpenARC 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.Mail::DKIMValimail 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.dkimpydkimpy 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.DalliDalli is high performance, pure Ruby client for accessing memcached servers and is maintained by Valimail.DNSAdapterDNSAdapter contains a set of useful adapter classes that present a common set of return types and errors for DNS services. This adapter layer makes it simple to swap in different DNS providers and was written by Valimail.PostshiftCreated and maintained by Valimail, Postshiftprovides an Amazon Redshift extension for ActiveRecord 5 (Rails 5) PostgreSQL adapter based off of the existing activerecord5-redshift-adapter.Mailman ARC patchValimail 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.OpenDMARCValimail 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.OpenDKIMOpenDKIM 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.devise-secure_passwordValimail wrote this password policy enforcement extension for devise-gem, which is a flexible authentication solution for Rails based on Warden.CoppertoneCoppertone, written and maintained by Valimail, provides a Sender Policy Framework (SPF) toolkit for Ruby and includes tools for parsing SPF DNS records, evaluating the result of SPF checks for received emails, and creating appropriate email headers from the SPF result.
DMARCDomain-based Message Authentication Reporting and Conformance builds on the widely deployed SPF and DKIM protocols, adding linkage to the author (“From:”) domain name, published policies for recipient handling of authentication failures, and reporting from receivers to senders, to improve and monitor protection of the domain from fraudulent email. Valimail is deeply involved in the DMARC working group at IETF, working to broaden and strengthen its reach.DKIMDomainKeys Identified Mail (DKIM CRypto UPdate) working group is chartered to update DomainKeys Identified Mail (DKIM, RFC 6376) to handle more modern cryptographic algorithms and key sizes. As shepherds of DCRUP (RFC 8301), Valimail played a key role in the publishing and availability of this standard. We advocate for cryptographic updates that make DKIM stronger.ARCThe Authenticated Received Chain (ARC) protocol allows Internet Mail Handlers to attach assertions of message authentication state to individual messages. As messages traverse ARC-enabled Internet Mail Handlers, additional ARC assertions can be attached to messages to form ordered sets of ARC assertions that represent authentication state along each step of message handling paths. Valimail and Google are two of the editors of the ARC specification. Together, we are working to build ARC as a supplemental but crucial piece of the current DMARC standard.
