Command time limit exceeded

[Robert Szentmihalyi]

Hi,

I keep getting:

postfix/pipe[7315]: B20F77718D: to=<mail at domain.com>,
relay=kolabmailboxfilter, delay=107430, status=bounced (Command time limit
exceeded: "/usr/bin/php")

I tried to set:
kolabfilter_destination_concurrency_limit = 500
kolabfilter_time_limit = 10000
kolabmailboxfilter_destination_concurrency_limit = 500
kolabmailboxfilter_time_limit = 10000
in /etc/postfix/main.cf as suggested here:
http://www.intevation.de/roundup/kolab/issue1256
It does not seem to help though...

Any ideas?

TIA,
 Robert
