    Hi<o:p></o:p>

    We have a system/application that sends emails to our customers. One of the customers using Broadcom/Symantec service and they cannot receive the emails. All other can.<o:p></o:p>

    I have seen several others here with similar problem. Here is the message we receive.<o:p></o:p>

    ----
    The IP Address 46.246.37.3 was found to have a negative reputation. Reasons for this assessment include:<o:p></o:p>

     <o:p></o:p>

        - The host has been observed sending spam in a format that is similar to snow shoe spamming techniques.<o:p></o:p>

        - The host is unauthorized to send email directly to email servers.<o:p></o:p>

    ----<o:p></o:p>

     <o:p></o:p>

    We have submitted the IP to be removed and it works a little while and then it getting have bad reputation again.<o:p></o:p>

    Also IP addresses never used getting this bad reputation from Broadcom.<o:p></o:p>

    I think it can be the whole range being blocked 46.246.37.0/24 for some reason.<o:p></o:p>

    <o:p>Please help and let me know if this is really an issue on our side or some unfortunate behaviour on </o:p>Broadcom/Symantec service used by our customer.

    Regards

    Liang
