README

The Message Submission Agent Diagnostics tool (msadiag) facilitates testing the compatibility of third party message submission agents.

This tool implements several tests via SMTP to ensure the target MSA is properly and securely configured. The following tests are ran with msadiag validate:

• The server must not allow authentication via plain-text connection (only with --strict).
• The server must support a modern TLS encryption protocol (TLSv1.2 or TLSv1.3).
• The server must use a valid certificate, verifiable using the Mozilla CA bundle.
• The server must support the SMTP AUTH extension.
• The server must support SASL authentication via CRAM-MD5, LOGIN, or PLAIN.
• The server must require authentication to submit messages.
• The server must reject invalid credentials.
• The server must not require authentication to submit messages after successful authentication.

composer global require librarymarket/msadiag
