    We are a travel agency and we send about 10 scheduled emails a day to our clients for a number of reasons:

    - Final Payment Reminders
    - Proof of Citizenship Reminders
    - Happy Birthday messages
    - Etc Etc

    We use an application called Gammadyne which ties to our database and then sends through our internal Exchange SMTP Server.

    The number of emails we send at a time can vary from 10 or 15 to 250 at a time. Trust me, we are not spammers. We use an outside source for our email marketing.

    My question is: "Would OPENDNS block outgoing bulk email sent through the OPENDNS DNS servers?" Is this considered suspicous activity since it's being routed through an internal 10.XXX.XXX.XXX ip number?

    Thanks.

    The email you send doesn't actually go through OpenDNS's servers. --Exchange could use OpenDNS to resolve the hostnames of the emails you're sending, but that's a bit different. Chances are you won't run into any problems on the OpenDNS side, unless they do limit the number of requests from a site within a short period of time. Chances are that 250 requests at a time isn't going to be a problem.

    I don't think we'd block anything... What makes you think we are? This is probably best sent in as a specific customer support request, FYI.
