[Dovecot] Dovecot and pigeonhole: mail not filtered

[Sebastian Schlingmann]

Hi everyone,

I am running dovecot for quite some time now (currently version 2.0.13).
Recently I tried to get Sieve and Managesieve to run. For this purpose
I installed pigeonhole 0.2.3 and added sieve to the mail_plugins for
lmtp and to the protocols. I also copied the sample 90-sieve.conf and
20-managesieve.conf into my /etc/dovecot/conf.d/ directory. In
90-sieve.conf I uncommented the sieve and sieve_dir options and set
them to my desired values.

After a restart of dovecot I was able to use my webmailer to add sieve
scripts via the managesieve protocol. However the sieve scripts do not
trigger.
Is there any way to test if sieve is even executed when a mail arrives?
mail_debug did not give me any relevant information.

BTW: I checked my sieve script with the sieve-test command and it would
execute the right action (move a mail into a directory).

Bye
Sebastian
