outgoing-mailgun is an extension for outgoing that adds the ability to send e-mails via Mailgun. Simply install outgoing-mailgun alongside outgoing, and you'll be able to specify "mailgun" as a sending method in your outgoing configuration.

Installation

outgoing-mailgun requires Python 3.10 or higher. Just use pip for Python 3 (You have pip, right?) to install outgoing-mailgun and its dependencies (including outgoing):

python3 -m pip install outgoing-mailgun

Configuration

When using "mailgun" as the sending method in an outgoing configuration, the following configuration fields are recognized:

base-url : HTTP URL (optional)

The base URL to use for Mailgun API requests. This should be either "https://api.mailgun.net" (the default) for domains in Mailgun's US region or "https://api.eu.mailgun.net" for domains in Mailgun's EU region. Trailing slashes on the URL are optional.

domain : string (required)

The domain name you registered with Mailgun for sending e-mail

api-key : password (required)

A Mailgun API key for your domain; see the outgoing documentation on passwords for ways to write this field.

When using the keyring password scheme or another scheme that takes optional host/service and username fields, if the service and/or username is not supplied in the password specifier, then the service defaults to the domain name of the base-url field, and the username defaults to the value of the domain field.

tags : list of strings (optional)

A set of tags to apply to sent e-mails

deliverytime : datetime (optional)

Desired time of delivery for sent e-mails; if no timezone offset is given, it is assumed to be in the local system timezone

dkim : boolean (optional)

Enable/disable DKIM signatures on sent e-mails

testmode : boolean (optional)

Whether to send in test mode

tracking : boolean (optional)

Whether to enable message tracking

tracking-clicks : boolean or "htmlonly" (optional)

Whether to enable clicks tracking in e-mails

tracking-opens : boolean (optional)

Whether to enable opens tracking in e-mails

headers : table with string values (optional)

A collection of custom MIME headers to append to sent e-mails

variables : table with string values (optional)

A collection of Mailgun variables to attach to sent e-mails

Example Configuration

[outgoing]
method = "mailgun"
domain = "mydomain.nil"
api-key = { file = "~/secrets/mailgun.key" }
dkim = true
tags = [ "sent-with-outgoing", "my-campaign" ]
tracking-clicks = "htmlonly"
headers = { Reply-To = "[email protected]" }
variables = { sender = "outgoing", foo = "bar" }

Sender-Specific Behavior

The MailgunSender class provided by this extension is a reentrant and reusable context manager, and its send() method can be called outside of a context. In addition, on success, the send() method returns the message ID of the newly-sent e-mail (without enclosing angle brackets).
