I logged in to webmin today and updated (beside some others) Spamassassin.
After the update (and reboot) Spamassassin seems not to work. Here is what a restart did:
[root@vps]# /etc/init.d/spamassassin restart Stopping spamd: [FAILED] Starting spamd: child process  exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 2588. [FAILED] [root@vps]#
(Since SPAM really annoys me and I am a bit impatient too I googled while checking this issue and found:)
I should after the upgrade run:
I did that, and then:
...and it worked fine.
I post that solved issue anyway in case somebody else got this error.
