Don't know whether this is related... No, that shouldn't be the problem. I just checked the Mailserver for the Domain tu-harburg.d400.de and the primary MX rztsun.rz.tu-harburg.de is able to handle mail for this domain, but the backup MX ixgate01.dfnrelay.d400.de and ixgate01.dfnrelay.d400.de are misconfigured. According to the DNS-Entries, they are the backup MX, but they are not configured to do so. So, this is a broken configuration and someone who has the approiate bounce message (with headers) available, should forward it with some explanation to postmaster@d400.de and mailer-daemon@dfnrelay.d400.de and let them fix their broken configuration. If you contact the primary MX rztsun.rz.tu-harburg.de directly, it will accept the email-address from above.
