About OpenDKIM
OpenDKIM provides a library and a milter-based filter that integrates with popular MTAs like Sendmail, Postfix, and Exim to sign and verify email messages using DomainKeys Identified Mail (DKIM). It supports RFC 6376 and can handle multiple signing domains, key rotation, and subdomain policies. The software includes tools for generating key pairs, testing DNS records, and monitoring statistics. OpenDKIM is maintained by the Trusted Domain Project and has been in active development since 2009. It runs on Linux and other Unix-like systems. Many large email providers and organizations rely on it to meet DMARC requirements and improve deliverability. The configuration is done through a single text file, and it can log detailed information for troubleshooting. OpenDKIM is a solid choice for anyone running their own mail server who needs a standards-compliant DKIM solution without vendor lock-in.
