[Dovecot] Using global und per-user sieve scripts at the same time

[Matthias Kellermann]

Hi list,

I'm trying to get a global sieve mailfilter with per-user sieve scripts
to work.

At the "lda"-section in the dovecot.conf file I have:
global_script_path = /usr/local/etc/sieve/spam

/usr/local/etc/sieve/spam:
require "fileinto";

if header :contains ["Subject"] ["***Spam***"] {
  fileinto "Spam";
  stop;
}

which will work fine delivering Spam Mails in a Spam dir for every user.
If a user creates his own .dovecot.sieve file the global script will not
work anymore.

How can I enable global and local per-user sieve scripts at once? Is
this possible? Do you know any workaround so all users will have the
same (Spam-)sieve filters beside there own (global templates or so)?
