mailmq

MailMQ

sendmail like mail-relaying via MQ.

When working with PHP and transaction email services, there's the super useful ssmtp, which works great, except that ssmtp is synchronous and if your mail relay is slow, it will slow your entire web request down.

Enter mailmq, which does the same thing, but via a producer-consumer model. You run an AMQP service, e.g. RabbitMQ, and a Celery worker that runs mailmq.server and then you can use mailmq.client to send email asynchronously.

The server is designed for Docker, so all configuration happens via the environment.

Server

Via Docker:

docker-compose up

Or directly:

CELERY_BROKER=localhost SMTP_HOST=mail celery -A mailmq.server worker

The following environment variables are supported:

• CELERY_BROKER - AMQP broker (required)
• SMTP_HOST - destination SMTP server host (required)
• SMTP_PORT - destination SMTP server port
• SMTP_USER - user for SMTP auth
• SMTP_PASS - password for SMTP auth
• MAIL_FROM - default sender (strongly recommended)

Client

Designed to have the same command line arguments as sendmail.

From pip:

pip install mailmq

With source:

python setup.py install

CELERY_BROKER=amqp mailmq -t << EOF
From: [e-mail]
To: [e-mail]
Subject: badger

Badger!
EOF

Or without installing:

CELERY_BROKER=localhost python -m mailmq.client [e-mail]

The following environment variables are supported:

• CELERY_BROKER - AMQP broker (required)

Add the following to your php.ini to use with PHP:

sendmail_path = "mailmq -t"

Running Tests Locally

Install PHPUnit, with an appropriate version of PHP also installed

and available locally.

Make python3 available. you might have to use virtualenv to do this.

e.g. mkvirtualenv --python=python3 .

Install celery locally with pip install -r requirements.txt

./tests/run.sh - this starts up the required docker containers,

configures PHP to use mailmq for sending email, then runs the phpunit tests defined in /tests
