secure-smtplib
Secure SMTP subclasses for Python 2
Decision gist · record as of 2026-08-14
No. The package is abandoned, targets Python 2, has an unclear license, and no known vulnerabilities. Modern Python's smtplib already provides robust TLS/SSL support. Use the standard library or a maintained alternative instead.AI-flagged interpretation of the facts on this page — verify before relying

# Use secure_smtplib.SMTP or secure_smtplib.SMTP_SSL with ca_cert parameter- Whether the package actually works with any currently-maintained Python version despite Python 2 targeting.
- What specific certificate validation improvements it provides over modern smtplib's built-in TLS support.
- Whether the unclear license permits commercial or derivative use.
What it is and what it does
secure-smtplib is a set of SMTP subclasses designed to add certificate validation to Python's standard smtplib, specifically for TLS/SSL connections. It was built to address the need to verify CA certificates when establishing secure SMTP connections.
The package has been unmaintained since 2015-04-07 and targets Python 2. It carries no known security vulnerabilities but offers no active development, documentation, or compatibility assurance for modern Python environments. The license status is unclear, adding legal risk to adoption.
Use it for
- Legacy Python 2 systems still requiring secure SMTP with explicit CA certificate validation.
- Auditing or understanding how to add certificate verification to SMTP connections in older codebases.
- Historical reference for SMTP security patterns in early Python implementations.
