I recently upgraded my Debian system to Jessie and noticed that spamassassin is not working after the upgrade. It seems the introduction of systemd broke it. I found these errors in my /var/log/main.err file:

Feb 1 14:11:11 host spamc[13232]: connection attempt to spamd aborted after 3 retriesActually all I had to do is enable spamassassin in systemd by typing
systemctl enable spamassassin
