Posted on 2009-12-28

I'M working on an sbs2008 server.  email is flowing just fine in and out.  The company has an old domain and wanted to accept email from that domain to this Exchange server.  We went under organization hub transport to "Accepted Domains" and entered the information needed and went to "Email Address Policies" and added the old domain email "".  When we send an email to the "old" domain were getting ndr's with no information.  Any help with this would be greatly appreciated.

thank you.

    If Exchange is rejecting the email then it would say in the NDR what the reason is.
    Therefore you need to verify whether the server is rejecting the message or something else is. It could be AV, Antispam etc. If you have MX records pointing to other servers then it could be that server rejecting the message.

    Use Telnet internally to confirm the server is accepting email for that domain.

    Simon AV, Antispam etc. is disabled.  We can telnet and send an email however if we type in "test" in the body or something in the subject it is stripped to blank.  We are still unable to send an email through normal means by Outlook client or web based yahoo mail.

    Sending email and receiving email are completely different.
    Being unable to send email to your server from Yahoo is a RECEIVING problem.
    Being unable to send email from your Outlook client or OWA is SENDING problem.

    They can be very different.

    AV/Antispam disabled or removed? If they are simply removed that is not enough. Due to the way they plugin in to Exchange they can still cause problems. They need to be removed and the server rebooted to prove they are not the cause of problems.
    When it comes to a telnet test you can also get errors from local AV software - McAfee for example can get in the way.

    Have you tested this domain from outside using one of the numerous domain testing tools - mxverify or

    I will reboot the server, send an email, if that fails I will try one of the testing tools you mentioned.  I will post back with an answer shortley.

    thank you again.
