About
The python-slimta
project is a Python library offering the building blocks
necessary to create a full-featured MTA. Most MTAs must be configured, but
an MTA built with python-slimta
is coded. An MTA built with python-slimta
can incorporate any protocol or policy, custom or built-in. An MTA built with
python-slimta
can integrate with other Python libraries and take advantage of
Python's great community.
The python-slimta
project is released under the MIT License. It is
tested for Python 2.7+ or 3.6+.
Getting Started
Use a virtualenv to get started developing against python-slimta
:
$ cd python-slimta/
$ virtualenv .venv
$ source .venv/bin/activate
(.venv)$ python setup.py develop
To run the suite of unit tests included with slimta
:
(.venv)$ pip install -r test/requirements.txt
(.venv)$ py.test
Running the Example
The example in [examples/slimta-mail.py
](examples/slimta-mail.py) provides a
fully functional mail server for inbound and outbound email. To avoid needing
to run as superuser, the example uses ports 1025
, 1465
and 1587
instead.
It needs several things to run:
An activated
virtualenv
as created above in Getting Started.A TLS certificate and key file. The easiest way to generate one:
openssl req -x509 -nodes -subj '/CN=localhost' -newkey rsa:1024 -keyout cert.pem -out cert.pem
- A populated [
examples/site_data.py
](examples/site_data.py) config file.
Check out the in-line documentation with --help
, and then run:
(.venv)$ ./slimta-mail.py
Manually or with a mail client, you should now be able to deliver messages. On
port 1025
, messages will go to unique files in the current directory. On port
1587
, messages will be delivered to others using MX records! To try out a TLS
connection:
$ openssl s_client -host localhost -port 1587 -starttls smtp
