[Dovecot] dovecot-sieve and ldap user

[spamvoll at googlemail.com]

hi..

im running dovecor 1.2.10 and dovecot-sieve 0.1.15

protocol lda {
..
  mail_plugins = sieve
}
plugin {
...
   sieve = ~/.dovecot.sieve
   sieve_dir = ~/sieve
}

cat .dovecot.sieve
require "fileinto";
if header :contains "subject" ["VIRUS"] {
fileinto "VIRUS";
} else {
keep;
}

But mails dont get moved.
I use the master.cf to get postfix to use deliver

Does the sieve plugin use the home_dir returned from the ldap ?
And is it ok to use the deliver in master.cf and or do i have to set
mailbox_command = /usr/lib/dovecot/deliver
?
