Hi Mike,
I have a solution and can confirm all is working well.  This is how to do it...
1.) Create a master sieve config file
sudo mkdir /var/lib/dovecot/sieve/
sudo vi /var/lib/dovecot/sieve/default.sieve
In that file, add:
require ["fileinto"];
# Move spam to spam folder
if header :contains "X-Spam-Flag" ["YES"] {
  fileinto "Junk";
  stop;
sudo chown -R _dovecot:mail /var/lib/dovecot
sudo sievec /var/lib/dovecot/sieve/default.sieve
2.) Add the SPAM sieve conf include to the main config
sudo vi /Library/Server/Mail/Config/dovecot/conf.d/90-sieve.conf
Add the following (you can use the existing sieve_before and modify it):
sieve_before = /var/lib/dovecot/sieve/default.sieve
3.) Ensure that the Junk Folder is automatically created and subscribed to by default
sudo vi /Library/Server/Mail/Config/dovecot/conf.d/15-mailboxes.conf
Replace:
mailbox Junk {
    special_use = \Junk
With:
mailbox Junk {
    auto = subscribe
    special_use = \Junk
4.) Restart all Mail server services using the Server.app
5.) Ensure that SPAM is going into the Junk folder correctly.  You can test here: http://www.emailsecuritycheck.net/
