Common interface for multiple e-mail methods

GitHub | PyPI | Documentation | Issues | Changelog

outgoing provides a common interface to multiple different e-mail sending methods (SMTP, sendmail, mbox, etc.). Just construct a sender from a configuration file or object, pass it an EmailMessage instance, and let the magical internet daemons take care of the rest.

outgoing itself provides support for only basic sending methods; additional methods are provided by extension packages.

See the documentation for more information.

Installation

outgoing requires Python 3.8 or higher. Just use pip for Python 3 (You have pip, right?) to install outgoing and its dependencies:

python3 -m pip install outgoing

Examples

A sample configuration file:

[outgoing]
method = "smtp"
host = "mx.example.com"
ssl = "starttls"
username = "myname"
password = { file = "~/secrets/smtp-password" }

Sending an e-mail based on a configuration file:

from email.message import EmailMessage
import outgoing

# Construct an EmailMessage object the standard Python way:
msg = EmailMessage()
msg["Subject"] = "Meet me"
msg["To"] = "[email protected]"
msg["From"] = "[email protected]"
msg.set_content(
    "Oh my beloved!\n"
    "\n"
    "Wilt thou dine with me on the morrow?\n"
    "\n"
    "We're having hot pockets.\n"
    "\n"
    "Love, Me\n"
)

# Construct a sender object based on the default config file (assuming it's
# populated)
with outgoing.from_config_file() as sender:
    # Now send that letter!
    sender.send(msg)

As an alternative to using a configuration file, you can specify an explicit configuration by passing the configuration structure to the outgoing.from_dict() method, like so:

from email.message import EmailMessage
import outgoing

# Construct an EmailMessage object using the eletter library
# <https://github.com/jwodder/eletter>:
from eletter import compose

msg1 = compose(
    subject="No.",
    to=["[email protected]"],
    from_="[email protected]",
    text=(
        "Hot pockets?  Thou disgusteth me.\n"
        "\n"
        "Pineapple pizza or RIOT.\n"
    ),
)

msg2 = compose(
    subject="I'd like to place an order.",
    to=["[email protected]"],
    from_="[email protected]",
    text="I need the usual.  Twelve Hawaiian Abominations to go, please.\n",
)

SENDING_CONFIG = {
    "method": "smtp",
    "host": "smtp.love.love",
    "username": "my.beloved",
    "password": {"env": "SMTP_PASSWORD"},
    "ssl": "starttls",
}

with outgoing.from_dict(SENDING_CONFIG) as sender:
    sender.send(msg1)
    sender.send(msg2)
