secure-smtplib (Python 2)

secure-smtplib is an abandoned Python 2 library (last released in 2015) that provides subclasses for the standard `smtplib` module to handle secure SMTP connections. Its functionality has been largely superseded by built-in improvements to the standard `smtplib` module in Python 3, which offers robust SSL/TLS support through `SMTP_SSL` and `starttls()` methods, often in conjunction with the `ssl` module. This library is not recommended for new projects or Python 3 environments due to its age and lack of maintenance.
