Spamassassin/SpamD Installation Guide
Ubuntu 18/20 or comparable Debian dedicated server
IMPORTANT: This article assumes you do not have
amavisd-new installed/running on the same system.
The Ubuntu/Debian amavisd-new package already uses and suggests Spamassassin be installed. If you installed the
amavisd-new package, SA was probably already installed and should not need much more tinkering.
Other than checking that the daily cron job is being run to refresh the SA rules (see below), this guide should not be needed.
spamd from the Spamassassin package should NOT be a parent process if you are using
amavisd-new, BUT should be installed (The spamassassin.service should not be enabled).
