[syslog-ng] local6 doesn't seem to work...

Hi, When I have the following in syslog-ng.conf: filter f_cyrus { level(warn, err, crit) and facility(local6); }; destination cyrus { file("/var/log/cyrus.log"); }; log { source(src); filter(f_cyrus); destination(cyrus); }; nothing is being logged in /var/log/cyrus.log however when I use: filter f_cyrus { level(warn, err, crit) and match("imap"); }; it works fine, why is local6 not working?? (cyrus-imap is default compiled with local6 enabled) Running on Suse 10.0 ( Cannot upgrade yet :-( ) with syslog-ng version 1.6.8 Greetings, Ruud Feringa.
