- Pagure's Milter
- ===============
- `Milter <http://www.postfix.org/MILTER_README.html>`_ are script executed by
- postfix upon sending or receiving an email.
- We use this system to allow pagure's users to comment on a ticket (or a
- pull-request) by directly replying to the email sent as a notification.
- Pagure's milter is designed to be run on the same machine as the mail server
- (postfix by default). Postfix connecting to the milter via a unix socket.
- The milter itself is a service managed by systemd.
- You can find all the relevant files for the milter under the ``milters`` folder
- in the sources.
- Install the milter
- ------------------
- The first step to enable the milter on a pagure instance is thus to install the
- ``.service`` file for systemd and place the corresponding script that, by
- default, should go to ``/usr/share/pagure/comment_email_milter.py``.
- If you are using the RPM, install ``pagure-milters`` should provide and install
- all the files correctly.
- Activate the milter
- -------------------
- Make sure the milter is running and will be automaticall started at boot by
- running the commands:
- To start the milter:
- ::
- systemctl start pagure_milter
- To ensure the milter is always started at boot time:
- ::
- systemctl enable pagure_milter
- Activate the milter in postfix
- ------------------------------
- To actually activate the milter in postfix is in fact really easy, all it takes
- is two lines in the ``main.cf`` file of postfix:
- ::
- non_smtpd_milters = unix:/var/run/pagure/paguresock
- smtpd_milters = unix:/var/run/pagure/paguresock
- These two lines are pointing to the unix socket used by postfix to communicate
- with the milter. This socket is defined in the milter file itself, in the
- sources: ``milters/comment_email_milter.py``.
