I am trying to move Spam detected by spamassassin automatically to the Junk folder on Debian Jessie.

I installed Spamassassin and edited the configs:

local.cf (spamassassin folder)

rewrite_header Subject *****SPAM*****

main.cf

spamassassin_destination_recipient_limit = 1

master.cf

smtp      inet  n       -       -       -       -       smtpd
        -o content_filter=spamassassin

spamassassin unix -     n   n   -   -   pipe
    flags=DROhu user=vmail:vmail argv=/usr/bin/spamc -f -e
    /usr/lib/dovecot/deliver -f ${sender} -d ${user}@${nexthop}

90-plugins.conf (dovecot)

plugin {
  #setting_name = value
  sieve = /etc/dovecot/sieve/default.sieve
}

default.sieve

require "fileinto";
if header :contains "X-Spam-Flag" "YES" {
    fileinto "Junk";
}

15-mailboxes.conf (postfix)

mailbox Junk {
   auto = subscribe
   special_use = \Junk
}

The Spam gets marked as *****SPAM***** correctly, but is not moved into the Junk folder (i use roundcube as mail client, the Junkfolder does not even show up. There are no errors in the mail.info log either:

In my case I was missing include conf.d/*.conf line in dovecot.conf and dovecot did not read configuration from these files including 90-plugins.conf.

But I did not include that line because all my config is already in dovecot.conf and conf.d/*.conf files will override it with default settings so I simply included these lines in dovecot.conf:

plugin {
    sieve = /etc/dovecot/sieve/default.sieve
}

protocol lda {
    mail_plugins = $mail_plugins sieve
}

All your other configuration is fine and should work (it seems that you get them from this answer).

To manage filter rule you can use sieve on dovecot. You can put it as global sieve or per user sieve.

For global sieve use configuration in /etc/dovecot/dovecot.conf :

sieve_global_path = /home/vmail/sieve/dovecot.sieve

For sieve per user use configuration :

sieve = /%Lh/sieve/dovecot.sieve

which %Lh===dovecot will change it to user mailbox dir

This is example for sieve files content:

if header :contains "*****SPAM*****" "YES"
{
    fileinto "Junk";
    stop;
}
