    Any antivirus products installed on the Exchange 2000 server? Those can cause that sort of message.
    I haven't seen it for a while, not with Exchange 200x, so you have to look elsewhere.

    Does the remote server send email directly, or via another server, appliance etc?

    yes the exchange 2000 got trend installed
    and the 2003 sends directly.

    What about the server that is doing the sending?
    Unfortunately if it is outside of your control you may not be able to do anything about it.

    Well I think the problem is on "my" exchange 2k server (smtp;554 5.6.1 Body type not supported by Remote Host), and in this case the remote host is the E2k server.

    I stick with my original diagnosis. I suspect the Antivirus. If you think that the problem is with your server then you will have to look at the AV configuration. If you cannot spot where there could be a problem, then the AV will have to be removed. There is no point in simply disabling it, as it will still have its hooks in Exchange. To test a problem with the AV you have to remove it.
    Once removed, get the message sent again. If the error message continues then you know that the problem is outside of the AV.

    I will take a look @ the AV.
