mail-auth
A Rust library for email authentication and reporting, supporting DKIM, ARC, SPF, DMARC, ARF, and SMTP TLS Reporting.
What is mail-auth?
mail-auth is a comprehensive email authentication and reporting library written in Rust. It provides robust implementations of key email security protocols including DKIM, ARC, SPF, and DMARC to help verify sender identity, ensure message integrity, and generate compliance reports. The library is designed to be fast, safe, and correct while supporting all major relevant RFCs.
Developers building email servers, mail transfer agents (MTAs), email security tools, or applications that need to sign, verify, or report on email authentication protocols in a Rust environment.
Developers choose mail-auth for its comprehensive, standards-compliant implementation of all major email authentication protocols in a single, performant Rust library, with a focus on safety and correctness. Its support for key generation, failure reporting, and multiple signature algorithms provides a complete solution over piecing together separate libraries.
