[Dovecot] Sieve isn't working

[Steven Weiß]

Hi,

I tried to get Sieve plugin running but I don't get it to work and 
actually have no idea what's wrong.

My dovecot version is 1.2.12 and dovecot -n prints this:

# 1.2.12: /usr/local/etc/dovecot.conf
# OS: Linux 2.6.18-028stab064.7 i686 openSUSE 11.1 (i586) reiserfs

  mail_plugin_dir: /usr/local/lib/dovecot/lda
  fsync_disable: no
auth default:
  passdb:
    driver: passwd-file
    args: /usr/local/etc/passwd.dovecot
  userdb:
    driver: passwd
  userdb:
    driver: static
    args: uid=popuser gid=popuser
plugin:
  sieve: /var/mail/mydomain/.dovecot.sieve
  sieve_global_path: /var/lib/dovecot/sieve/default.sieve
  sieve_dir: /var/mail/mydomain/sieve
  sieve_global_dir: /var/lib/dovecot/sieve/global/


For testing purposes I created a very simple 
/var/mail/mydomain/.dovecot.sieve with the following content:

require ["fileinto", "regex"];

if address :is "from" "t...@test.de" {
        fileinto "INBOX.Webi";
        stop;
}

Then I sent a mail from t...@test.de (the real address is ommitted here) 
to my mail account, but the mail is not moved to the subfolder Webi. In 
the log files there's no single hint what's going on. And in 
/var/mail/mydomain there's no .dovecot.sieve.log file.
This directory is owned by popuser and that user has rights for reading 
and writing to this directory (and read rights for .dovecot.sieve), 
therefore it should not be a rights problem.

Does anybody has suggestions what could be the cause of this?

Sincerely, Steven
