the solution is:

this sendmail version does not set the fully qualified domain name (FQDN) in the $w Makro, but
the comparison with the MX-RR is made with the $w Makro and therefore netway can not 
recognize itself because netway and netway.rz.uni-ulm.de are different.

make the following:

set the $w Makro to the FQDN explizit: Dwnetway.rz.uni-ulm.de
set the $A Makro to the unqualified domain name: DAnetway
replace all occurences of $w with $A in the .cf file

many thanks to all replies on the net. i was ill after my question and my news-grabber
didn't save the headers, and therefore i can't say my thanks to the man who helped me
with the right hint, but it was the following article number and text [no trailers :-(]:

many thanks explicit to this author :-(thanks)
