Hello guys,

well, the problem turned out to be something completely different from
postfix... actually it was the buggy trustees software. i didn't dig
deep into the problem, but simply deactivating it solved everything
(the authors doesn't really seem to be interested in the bug..)
so anyway, sorry for bothering the list with something what turned out
not to be a postfix-problem
thanks
