Valimail engineers get the opportunity to make a meaningful impact by improving on the core communications platform used by more than 3.8 billion people every day: Email.
Our Engineers Are Solving the Fundamental Flaw of Email
We wouldn’t say we’re making email sexy, but we’re on a mission to make it trusted. And isn’t trust the basis of every solid relationship?
Sex appeal fades, but trust can last a lifetime.
We Get Things Done
We Are Active Contributors to the Ecosystem
Our CTO and Co-Founder is the maintainer of Dalli, and our engineers have contributed to multiple open-source standards that power and advance the internet for everyone.
ARC Test Suite
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.
Dalli is high performance, pure Ruby client for accessing memcached servers and is maintained by Valimail.
DNSAdapter 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.
Created and maintained by Valimail, Postshift provides an Amazon Redshift extension for ActiveRecord 5 (Rails 5) PostgreSQL adapter based off of the existing activerecord5-redshift-adapter.
Mailman ARC patch
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.
Coppertone, 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.
Authentication Headers, written and maintained by Valimail, is a Python library for the generation of email authentication headers. The library can perform DKIM, SPF, DMARC, and ARC validation and generate and affix the corresponding headers.
