# Advanced Filter
|
|||
|
|
|
|||
|
|
## Postfix Filters
|
|||
|
|
|
|||
|
|
There are two types of Postfix mail filters: Simple Filters and Advanced
|
|||
|
|
Filters. Simple Filters are executed for each incoming email as a new
|
|||
|
|
process, which may turn out to be expensive in terms of resources. Advanced
|
|||
|
|
Filters work as a mail-processing proxies.
|
|||
|
|
|
|||
|
|
For detailed documentation, see [FILTER README](https://www.postfix.org/FILTER_README.html).
|
|||
|
|
|
|||
|
|
## Installation
|
|||
|
|
|
|||
|
|
Just use the following command to install dependencies:
|
|||
|
|
|
|||
|
|
pip install -r requirements.txt
|
|||
|
|
|
|||
|
|
## Configuration
|
|||
|
|
|
|||
|
|
Lacre Advanced Filter, also known as daemon, is configured in the `[daemon]`
|
|||
|
|
section of configuration file. Two obligatory parameters to be defined there
|
|||
|
|
are:
|
|||
|
|
|
|||
|
|
* `host` -- IP address or a host name;
|
|||
|
|
* `port` -- TCP port Lacre should listen on.
|
|||
|
|
|
|||
|
|
The other very important section is `[relay]`, which by default uses Simple
|
|||
|
|
Filter destination. It has to be adjusted for Advanced Filter to work,
|
|||
|
|
setting port to `10026`.
|
|||
|
|
|
|||
|
|
Command to spawn a Lacre daemon process is:
|
|||
|
|
|
|||
|
|
GPG_MAILGATE_CONFIG=/etc/gpg-mailgate.conf PYTHONPATH=... python -m lacre.daemon
|
|||
|
|
|
|||
|
|
Two environment variables used here are:
|
|||
|
|
|
|||
|
|
* `GPG_MAILGATE_CONFIG` (not mandatory) -- path to Lacre configuration,
|
|||
|
|
unless it's kept in default location (`/etc/gpg-maillgate.conf`).
|
|||
|
|
* `PYTHONPATH` (not mandatory) -- location of Lacre modules. You can place
|
|||
|
|
them below your Python's `site-packages` to be reachable by any other
|
|||
|
|
Python software.
