  • Has anyone seen this in an NDR before?!

    Hi I was wondering if anyone had had this problem and could shed some light?

    A supplier is having difficulty sending email to our customer - they are getting:

    Code:
    [email protected] on 29/06/2010 11:57
    You do not have permission to send to this recipient.  For assistance, contact your system administrator.
    <mail.TheirSupplier.co.uk #5.7.1 smtp;554 5.7.1 Extreme Bad IP Profile>
    Even trusty Google can't find anything, which I think is slightly bizarre.

    I'm doubtful it's our customer's exchange server, as they have a huge number of other suppliers/partners etc and they don't have any problem at all. I'm thinking it's probably the supplier, but they are reporting it to us to resolve.... We do not support them and do not have any access, but without any reference to the above message, I've got nothing to go back to them with?

    Also so far it seems to be a single user at the supplier's end sending to any one of a number of recipients at our customer's site, as other Supplier users can email our Customer (in fact they did so to forward the above NDR).

    Thanks in advance!

    It is an antispam message from a cpanel addon (exim smtp).

    So it is probably a misconfig on their side of it.

      Oh BTW you can tell because they use the word "Extreme" in everything. Even their changelog has the word Extreme all over it.

        It is not an Exchange message.
        A lot of companies will pass the buck on NDRs because their server is not listed in the NDR. That doesn't matter. The server in the NDR is the one that was forced to generate the NDR. It was forced to do that because the next server in the hop rejected the message.

        It is like you refusing a package being delivered by DHL/UPS/Fed Ex and rather than being your fault, it is the fault of DHL/UPS/Fed Ex.

        NDRs can contain any text that you like - mine are all customiu

          NDRs can contain any text that you like - mine are all customised to include a link to my web site with an explanation. Therefore the fact that you cannot find anything in Google isn't surpising.

            Ah, yes of course - thank you both.

            It's a shame I can't see their setup, it would make it a lot easier.

            Thanks again.
