bote 1.0.0

Send email messages and enforce encryption.

Bote

"Bote" is German for messenger or courier. The bote library sends plain-text email from localhost or a remote SMTP server. The base functionality is in the standard library. Reasons to write yet another package were:

• Enforce that any connection to a SMTP server - except localhost / 127.0.0.1 / ::1 - is encrypted. (Of course this does not influence how the SMTP server sends the message to the recipient.)
• Extensive testing
• Type-Hints in the code (PEP 484)
• Good error messages
• Automatically wrap messages to 80 characters.
• Modularity

How to use it

import os
import bote

mail_settings = {
    'server': 'smtp.example.com',
    'server_port': 587,
    'encryption': 'starttls',  # or 'ssl', or 'off'
    # Best practice: get secrets from environment variables
    # instead of hardcoded strings =>
    'username': os.environ.get('MAIL_USER'),
    'passphrase': os.environ.get('MAIL_PASSPHRASE'),
    'recipient': '[e-mail]',
    'sender': '[e-mail]'}

mailer = bote.Mailer(mail_settings)

mailer.send_mail('Test bote',  # subject
                 'It worked!'  # mail body
                 )

You should not store secrets in code that may be shared or saved to source control. To avoid accidental exposure of secrets it is best practice to use environment variables that can be accessed with os.environ.get(). The python-dotenv could be useful for this too, but do not forget to add .env files to .gitignore.
