/kolab/sbin/postconf -d | grep _dns_
disable_dns_lookups = no

I changed it to "yes" and now this works without timeout and forced 
relaying :-)

Speaking about default config:
I would also vote for a config of
delay_warning_time = 3h
in main.cf.template. Some users wonder when the get a "could not deliver" 
message after 5 days. So an early warning that there is a problem is here 
necessary.

now to the slave bouncing problem...
