PostfixAdmin's fetchmail

This project contains all sources to build the container image docker.io/volkerraschek/postfixadmin-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.
