What it is

Mail is a pure Ruby library for generating, parsing, and sending email messages according to RFC standards. It provides a single unified API to construct email objects programmatically, parse raw email strings into structured objects, and send via SMTP/POP3. Unlike its predecessor TMail, it leverages modern Ruby's superior text encoding support to handle MIME multipart messages, attachments, and character encodings cleanly. Modular single-library structure under lib/mail/: core Message class in lib/mail.rb; email field types in lib/mail/fields/ (BCC, CC, Date, Content-Type, etc.); encoding/transfer mechanisms in lib/mail/encodings/; structured element parsing in lib/mail/elements/…

Start here

Open these first:

• lib/mail.rb — Entry point that requires and exposes all Mail gem functionality; every developer must understand the public API surface…
• lib/mail/message.rb — Core Message class representing email objects; the primary abstraction that handles headers, body, attachments, and…
• lib/mail/header.rb — Header management system that parses and stores all email headers using a FieldList; critical for understanding message…
• lib/mail/field.rb — Field abstraction that routes different header types to specialized field classes; fundamental to the plugin-like field…
• lib/mail/parsers.rb — Parser registry and dispatch system for all RFC 5322 compliant email parsing; required to understand how raw email text is…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/mikel/mail.git && cd mail && bundle install && bundle exec rake test

Daily commands:

bundle exec rake test (runs full test suite). For interactive exploration: bundle console opens a Ruby REPL with mail loaded. No server to start—this is a library, not an application.

Key cautions & unknowns

• Slowing — last commit 7mo ago
• Email parsing is highly forgiving by design (handles malformed headers gracefully) but strict serialization (to_s) produces RFC-compliant output—roundtrip may normalize whitespace/encoding. Character encoding must…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
