[sork] qmail driver for vacation

[Oscar Retana]

Hello!

I'm trying the HEAD version of vacation (Horde3, IMP4), using the qmail 
driver. It seems to me there is some configuration missing, not included 
or not documented. What's the "dbtype"? In the configuration file I 
don't see anything related to this parameter, however, it is used in the 
qmail driver:

horde/vacation/lib/Driver/qmail.php (near line 80):
---------------------------------------------------
// We need to find out what type of database file to use.
$conf = &$GLOBALS['conf'];
$dbfile = VACATION_BASE . '/files/empty.' .
   $this->params['dbtype'] . '.bin';

What this parameter should be?

Thank you for any help!

These are the errors I'm seeing:
--------------------------------
