SpamAssassin

A SpamAssassin docker container running on Alpine Linux.

This image is designed to listen on port 783 for third-party integration, and is not a full-featured spam solution. It was created primarily for integration with Mailpit.

By default all DNS checks including rDNS (reverse DNS) are disabled to vastly improve performance and account for local testing, however all DNS checks (including rDNS) can be enabled by adding the DNS_CHECKS=1 environment variable.

Spam rules are automatically updated daily and on startup.

Usage

docker run -d \
    -p 783:783 \
    --name spamassassin \
    axllent/spamassassin

To enable DNS tests:

docker run -d \
    -p 783:783 \
    -e DNS_CHECKS=1 \
    --name spamassassin \
    axllent/spamassassin
