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.
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
