  • Mail Delivery System

    Hi,

    For three months i received in my mailbox the fellow error :

    Delivery status Notification

    The problem is : I didn't send any mail for this organisation for example :

    [email protected] or [email protected]

    I tested my exchange 2007 for the open relay and there isn't open relay. I scanned my pc with avg, bit defender, malaware byte, spybot and g-data nothing... I scanned the exchange server 2007 with symantec endpoint nothing... I changed my AD password but the problem is always presents. Finnaly i closed the internal path port smtp of my cisco's router for all internal network and accepted only my exchange server.

    Do you have any ideas for resolve my problem ?

    Thx for your asnwer

    Re: Mail Delivery System

    It's a form of "reverse spam" - basically, someone else has forged their email headers, and is sending emails "from" your address, or domain

    so what happens is they send an email, with your return address, and it fails to deliver, for whatever reason. Then the mail server, as it is supposed to do, returns a non-delivery-record to the person who "sent' the email - in this case, it thinks it is you.

    unfortunately, there's not much you can do.

        To the best of my knowledge, nothing much will help you.

        Unfortunately, things outside your control are outside your control. The same issue does affect everyone.

        It's possible that something like SPF would work, but I can't guarantee that.

            If you are getting the NDRs for spam, then it is highly unlikely that the site that is sending the NDRs to you will have implemented SPF records. If they cannot get the basics correct, like rejecting email for unknown recipients at the point of delivery, then it unlikely they are doing anything as advanced as SPF record lookups.

            A few vendors have attempted to implement backscatter protection, but this is very hard to do because of the way NDRs work. As already stated, this usually means you have to put up with it.

                The only solution is to change your email address.
                If there was a simple solution then I would have posted it.
