slimta is a configurable MTA based on the
python-slimta libraries. While
the purpose of the
python-slimta library is to avoid configuration files and
allow full control via Python code, the
slimta project recognizes that not
everyone will want or need that level of control. Setup, configuration, and
slimta is designed to be familiar to non-programmers.
slimta project is released under the MIT License.
slimta from PyPi:
$ sudo pip install slimta
Pip should pull in all the required dependencies. Next, we create the basic configuration files:
$ slimta-setup config
This creates 3 files, in
~/.slimta/ or wherever you specified. The sample
configs are designed to work out of the box, so lets give it a shot:
$ slimta --no-daemon
In another terminal, let's connect to port 1025 to see if it's working. After
the banner (the line beginning with
220), type in
QUIT to end the session:
$ telnet localhost 1025 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 localhost.localdomain ESMTP example.com Mail Delivery Agent QUIT 221 2.0.0 Bye Connection closed by foreign host.
Port 1025 is fully capable of accepting mail in the SMTP session, but is
configured by default with the
blackhole relay to silently discard messages.
You can also try it out with the built-in Python SMTP libraries:
$ python >>> import smtplib >>> smtplib.SMTP('localhost', 1025).sendmail('email@example.com', ['firstname.lastname@example.org'], 'test message')
At this point, we're still a little ways off from where you'd probably like to
be: actually sending and receiving email to the Internet. Please check out the
Usage Manual for information on configuring
slimta to your liking,
including more advanced and custom setups.
