email_proto

email_proto is a Python library that provides sans i/o implementations of email protocols.

It also provides reference implementations with i/o.

Installation

Download from here?

NOTE: The unittests require that you install all supported async i/o backends pip install anyio curio trio, but these aren't dependencies of this project itself, only if you want to use those i/o backends.

(Hopefully this can get hosted on pip someday)

Usage

import getpass
import from email_proto.smtp_socket import Client # reference synchronous sockets implementation

client = Client()
client.connect ( 'smtp.yourdomain.com', 465, tls = True )
client.helo ( 'localhost' )
client.auth ( 'zaphod@beeblebrox.com', getpass.getpass ( 'Password:' ) )
client.mail_from ( 'zaphod@beeblebrox.com' )
client.rcpt_to ( 'ford@prefect.com' )
client.data ( b'(email content here)' )
client.quit()

TODO

STARTTLS implementation in asyncio is WIP. It is untested and feels dirty.
