I'm not that familiar with postfix, but the issue does look rdns related.

Under sendmail, on hosts with multiple names you have to make sure the 
hostname it uses to make the connection is the one that all your reverse 
dns is setup for.
(your rdns does resolve backwards and forwards , but the ptr cruwe.de is 
possibly not what your mail server advertises its hostname with ( not 
neccesarily the same when you telnet in the make an incoming conn).

#dig -x 188.40.164.98 +short
cruwe.de
If you mail me direct i can tell you what hostname i see, thats the one 
i'd try adding the rdns for.

Paul.
