dovecot - May 2017 - Sieve GLOBAL + Sieve LOCAL

Hello List,

I am using dovecot:

doveconf -n | grep -i sieve

protocols = " imap lmtp sieve pop3"
service managesieve-login {
   inet_listener sieve {
   mail_plugins = " quota sieve"
   mail_plugins = " quota sieve"

I would like to have a Global and per user based Local sieve_before 
file.

Since doveconf does not indicate I believe my version does not support:

sieve_global_path

     A path to a global sieve script file, which gets executed ONLY if 
user's private Sieve script doesn't exist, e.g. 
/var/lib/dovecot/default.sieve. Be sure to pre-compile this script 
manually using the sievec command line tool, as explained below.

But what I would need is execute a global sieve_before for all users to 
apply some spam selection rules. Did anybody easily achieved it?

An obvious workaround would be to create a script which goes through all 
current users mail directories and creates a sieve_before script with 
the settings I need and then modify the user creation to do the same 
when new mailboxes get created.

Thank you!

Is this what you are looking for? This is how I enforce spam rules prior to
users' custom scripts.

#in dovecot configuration
plugin {
  sieve_before = /var/lib/dovecot/sieve/global/default.sieve
}


#In /var/lib/dovecot/sieve/global/default.sieve
require ["fileinto"];
if header :contains "X-Spam-Flag" "YES" {
        fileinto "Spam";
        stop;
} else {
        keep;
}

Doesn't 'keep' imply 'stop'?  What if your users want the
email in a different folder that the INBOX?

Leave the 'else' clause off.
