Moving emails tagged as spam to the Junk folder

[Mika Leppänen]

 I am running Ubuntu 16.04. I am following this guide: 
https://wiki2.dovecot.org/HowTo/AntispamWithSieve. At the end when I try 
to compile the .sieve files, I get this error: sievec(root): Fatal: 
Plugin 'sieve_imapsieve' not found from directory 
/usr/lib/dovecot/modules/sieve.  Does anyone know about this?
I have dovecot-sieve installed and I'm using Postfix and Spamassassin.
