Procmail stopped working?

Hi,

I have the following recipes:

LOGFILE = "procmail.log"
MAILDIR = /var/mail/folders/tolga
:0
* ^From(_dot_)*procmail-bounces(_at_)lists(_dot_)RWTH-Aachen(_dot_)DE
Procmail
:0
* ^Sender(_dot_)*kvirc-bounces(_at_)lists(_dot_)omnikron(_dot_)net
KVIrc
:0
* ^From(_dot_)*noreply(_at_)couchsurfing(_dot_)com
* ^Subject:.*[CS msg:*\]
{
   :0c
   CS
   :0
   ! gokce(_dot_)ozses(_at_)nielsen(_dot_)com
}

* ^From(_dot_)*errors(_at_)hospitalityclub(_dot_)org

   ! gokce(_dot_)ozses(_at_)nielsen(_dot_)com
}
:0
* ^From(_dot_)*fatura(_at_)smileadsl(_dot_)com
* ^Subject:.*Smile Fatura
! tatlimcik(_at_)hotmail(_dot_)com
:0
* ^Subject:.*Anacron*
/dev/null

and the following .forward file:

"|IFS=' ' && exec /usr/bin/procmail || exit 75 #tolga"

But it suddenly stopped working. I don't know why. It just doesn't log, 
it just doesn't filter. Can you help me with that?
