Global vs per-user Sieve scripts

Global scripts run for every user. Per-user scripts are uploaded via ManageSieve.

conf.d/90-sieve.conf:

plugin {
  sieve = file:~/sieve;active=~/.dovecot.sieve
  sieve_before = /etc/dovecot/sieve/before.sieve
  sieve_after  = /etc/dovecot/sieve/after.sieve
  sieve_dir = ~/sieve
  sieve_extensions = +editheader +mailbox +spamtest
}

Execution order: sieve_before → user script → sieve_after.

Common global rules in before.sieve:

require ["fileinto", "spamtest", "spamtestplus"];

if spamtest :percent :value "ge" "75" {
  fileinto :create "Junk";
  stop;
}

Compile after editing:

sievec /etc/dovecot/sieve/before.sieve

🎯 Always test new global rules with one mailbox first — a broken before.sieve breaks delivery for everyone.
