PostfixAdmin's fetchmail

This project contains all sources to build the container image docker.io/volkerraschek/fetchmail. The primary goal of the image is to fetch mails from external servers and forward them to on local running mail server.

The configuration file will be automatically generated based on information from a supported database backend of postfixadmin. The information are stored in the table fetchmail of the database scheme of PostfixAdmin.

Usage

Possible database types are my for MySQL and Pg for postgres. Make sure that the database and the SMTP server are accessible. Otherwise, adjust the enclosed docker-compose or docker command accordingly. Alternatively you can use docker-compose in addition to the docker commands.
