  • Hello,

    i have this strange thing going on.

    80% of my incoming mail is bounced. some make it trough, but most dont.

    Nothing is changed on the exchange server.
    i already looked up the error code, only it told me that there is not enoufg disk space in the server/mailbox. i have about 10gb free and removed the limit.

    Can anyone help me?

  • Hi

    Do you have any sort of local spam software installed on your Exchange server(s)?

    You want to look in the SMTP protocol log to see the SMTP commands and
    the status codes returned by the receiving server. The message will
    have no indication of how the SMTP client and server converse.

    I'm sorry, but that's not helpful. What commands are rejected?
