  • Bounce notifications

    We have recently upgraded from Exchange 2000 to 2007 and one feature we used to have I cannot find where to turn it back on. Basically every bounce message our server sends used to be copied to the administrator mailbox which IT checked several times a day. This ensured that any misspelt emails could be found and forwarded on without having to relay on the customer resending.

    I have searched but cannot find where this is enabled in 2007. Help!

    You don't want to enable that feature.
    By doing so it means your server is exposed to an NDR attack. What you should really do is install the antispam agents then enable recipient filtering. The sender then gets an NDR immediately.

    Remember - that was just a COPY of the NDR, the sender still got an NDR. In my experience senders were then confused when people replied to an email that they got an NDR from.

      The main reason for admins getting copies of them would have been to show them which other aliases they should have considered adding to a user's account. Eg a user with email address [email protected] could also be setup to receive mail to [email protected] - while some of these are common sense guesses, common stupidity always triumphs over common sense

        We use a third party company to do our email filtering for us. I need the feature to capture missplet emails which are often client & time critical to then forward the original to the correct address.

          Unless the remote filtering company is doing recipient validation then their checks will not deal with NDR spam. That is why it is such a problem. Your server MUST accept NDRs that are destined for it. Things are fine until you come in one morning and find your server has 150,000 messages in your queues. It only has to happen once and you will learn.

          If they are time critical then why do you only check them several times a day. Reject the email at the point of delivery, preferably using your external service provider and the sender will know instantly that the message has failed. Don't comprise your network security because of user stupidity.

            I think the question is mis understood here. What i understand from my friend is that he is taking about the option "Send copy of non delivery report to" under messages tab > Default SMTP Virtual Server.

            Since in exchange 2007 their is no SMTP Virtual Server, It's all send connectors now which works like SMTP Connectors.

            To have that option enabled under exchange 2007 you need to follow this article
            http://technet.microsoft.com/en-us/l.../bb400930.aspx

            and these two sub sections
            Copying Internal NDRs to a Mailbox
            Copying External NDRs to a Mailbox

            Let me know if that resolves ur issue and if i mis understood ur concerns.

            Note: Whenever the issue gets resolved just put a lil note saying "Issue Resolved" if you found out the solution mention that too.
