[Dovecot] sieve vacation error

[Andre Rodier]

Hello everybody,

First, I want to thank the development team for the quality and the 
stability of dovecot. It's now running without problem since two years 
on my debian box.

Next, I'd like you help me to solve the problem I have with 
vacation/sieve script. My configuration is debian lenny, with standard 
dovecot packages (1.0). I have setup the sieve plugin, using roundcube 
on another machine, and filter is working fine. fileinto is working, as 
well as forward and discard. However, vacation is not working at all, 
and I have no error message. The mails sent to the account marked as 
vacation are received, but the auto answer process is not working.

Here the successful logs from the vacation reject script, that I 
temporary use:

Here my questions :

    * If the sieve vacation script had to use a counter for limits per
      day, where this counter is supposed to be stored ? I cant see any
      dovecot file. I have temporary try to use 0777 for
      home/sieve/maildir folders, but no file is created at all.
    * Is it the same process used to forward, discard and finally vacation ?
    * I use virtual file for users on postfix, and I also have a LDAP
      server for authentication. Do I have something to configure on
      dovecot to be sure that vacation is working with this configuration ?
    * As you may have noticed above, mails are redirected to localhost
      users. ( c.f X-Original-To: some.user at red2.co.uk and Delivered-To:
      some.user at localhost ) Is this can affect the process ? ( Remember
      that forward and reject is working ).
    * Is there a way to debug the vacation process ?

Thanks for your help.

André Rodier.
