MemberVisite websiteCIS harnesses the power of a global IT community to safeguard public and private organizations against cyber threats.
DNSAdapter
Visite websiteDNSAdapter 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.
Postshift
Visite websiteCreated 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 patch
Visite websiteValimail 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.
OpenDMARC
Visite websiteValimail 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
Visite websiteOpenDKIM 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_password
Visite websiteValimail wrote this password policy enforcement extension for devise-gem, which is a flexible authentication solution for Rails based on Warden.
Coppertone
Visite websiteCoppertone, 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
Visite websiteAuthentication 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.
Sympa
Visite websiteSympa is an electronic mailing list manager used to automate list management functions such as subscription, moderation and management of archives.
DKIM
Visite websiteDomainKeys 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.
ARC
Visite websiteThe 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.
