Default Spamassassin install from Ubuntu is a little bit misconfigured and is not suitable for remote Anti-Spam service. So I am writing up the config changes I had to make in order to make it work flawlessly.<\/p>\n
1. Make a dedicated user for Spamassassin, default config runs Spamassassin as root, then the executable itself would complain about it and fall back to nobody.<\/p>\n
sudo adduser spamd --disabled-login<\/pre>\n2. Open \/etc\/default\/spamassassin and edit the following line<\/p>\n
OPTIONS=\"--create-prefs --max-children 5 --username spamd --helper-home-dir \/home\/spamd\/ --listen=0.0.0.0 --allowed-ips=(your_server_ip)\"<\/pre>\n3. Edit \/etc\/spamassassin\/local.cf and Add\/Uncomment the following lines to suit your needs<\/p>\n
