Mailing services with HTTP Api

💨💨💨 Pyuubin – Mailing System 💨💨💨

Asynchronous mailing system over HTTP API.

郵便 (Yūbin) - Postal Service

ぴゅー (Pyu-) – SFX for a sudden burst of speed, like running away from something

Installation

pip install pyuubin

Installation from source

pip install .

Running the service

You need to run the API and Worker for the system to work.

The API

Use hypercorn or uvicorn to run it

hypercorn pyuubin.api.app:app --access-log - --error-log -

The Worker

$ python -m pyuubin.worker --help
Usage: worker.py [OPTIONS]

  Run the worker.

Options:
  -n, --name TEXT                 Name of the service
  -w, --workers INTEGER           Number of workers
  -d, --debug                     Enable debug mode.
  -e, --print-environment-variables
                                  print environment variables to be put in
                                  .env file for configuration
  --help                          Show this message and exit.

Configuration

You can configure Pyuubin by using environmental variables. List of variables is available on running

$ python -m pyuubin -e
PYUUBIN_REDIS_PREFIX=pyuubin:
PYUUBIN_REDIS_MAIL_QUEUE=pyuubin::mail_queue
PYUUBIN_REDIS_URL=redis://localhost:6379
PYUUBIN_SMTP_HOST=smtp.gmail.com
PYUUBIN_SMTP_PORT=465
PYUUBIN_SMTP_USER=[e-mail]
PYUUBIN_SMTP_PASSWORD=SecretStr('**********')
PYUUBIN_SMTP_TLS=True
PYUUBIN_MAIL_FROM=[e-mail]
PYUUBIN_MAIL_RETURN=[e-mail]
PYUUBIN_MAIL_CONNECTOR=pyuubin.connectors.smtp
PYUUBIN_AUTH_HTPASSWD_FILE=

Note that the password is a SecretStr type from pydantic, so in your .env. file please just write your password without SecretStr(), so actually what you want is: PYUUBIN_SMTP_PASSWORD=secret

Pyuubin supports .env files. You can create one quite easily by running above command and directing the output to a .env file.

$ python -m pyuubin -e > .env
$

Then edit this file, put the values required and run the app.

Authentication - Password File

Generating passwords with htpasswd:

htpasswd -Bc test_htpasswd app1

Note: Only blowfish encrypted hashes are supported
