Global sieve script possible?

[Christian Rößler]

Good evening,

in the way of preparing a migration to Kolab I am wondering if it is
possible to use a global sieve script, which will be executed before
user's sieve scripts?

I was not able to find much in the net (eg. for example
<http://lists.andrew.cmu.edu/pipermail/cyrus-devel/2007-January/000239.html>) 

or in the Kolab documentation. So I would be thankful if anyone could
hint me whether this is possible, and if so, how.

Or would it suffice to put a (compiled, of course) sieve script into
/kolab/var/imapd/sieve/global?

Best regards,
Christian
