master to slave transport is explicit controlled by
/kolab/etc/postfix/ldaptransport.cf
This generates an smtp:[slave-domainname] transport for every multi domain 
user with home server != master server. 

But when I know this is a master-slave connection nobody forbids me to disable 
DNS lookups in master.cf as special service:

ms_smtp    unix  -       -    n    -    -   smtp -o disable_dns_lookups=yes

and in ldaptransport.cf
--  result_filter = smtp:[%s]
++  result_filter = ms_smtp:[%s]

Looks like this works. Objections from anyone?

Bye
