Maildelivery problem with postfix at some domains

At the Postfix mailserver i have this problem: eMails are not delivered to every target domain.
As example web.de was not send, gmx.de send without problems.
After searching the problem is a exchange host in the mail chain, and the target mailserver has a wrong option.

He cannot recognize the mime version.
 I added this to my main.cf and solved so the probmem:

smtp_discard_ehlo_keywords = 8bitmime 
smtpd_discard_ehlo_keywords = 8bitmime
