  • Alternate Email Delivery

    Setup is as follows:

    Exchange Server 2003
    Server 2003

    We have 8 sites in our org that are connected via VPN tunnels through SonicWALL appliances.

    One of our sites has replaced the ISP and at this time the router is blocking all our attempts to get the VPN tunnels back up and working again.

    We have users who are sending email to this site, they have their own email domain name, and they are obviuosly being held in the queues as the system cannot get to the server.

    I've created a SMTP connector that should be sending email to that domain direclty but it is at this time not working.

    Is there anything i can do to deliver this email while we get the tunnels operational??

    So the emails are queuing on your server for delivery to the remote server?
    Could you set up RPC/HTTPS so the remote users can point outlook direct at your server -- only port you would need to allow is 443

      If only it were that easy Tom.

      All of the servers are members of our Exchange organisation but the users for each mail domain have their own servers, e.g our .com.au guys have a server in Brisbane and our .co.nz users have their own server in Auckland.

      What i need is to setup a connector to send all email addressed to our .co.nz guys to be sent directly to them, easy you say setup a connector and send it via the internet. Unfortunately my understanding of the way email delivery is within an organisation is that it will send it via the routing groups.

      I need to bypass this temporarily to get email flowing to this site.

      BTW external email delivery works perfectly. Just "internal" between the organisation.

        You aren't going to be able to do this with SMTP Connectors.

        Exchange knows the email is internal, the fact that they have an SMTP address in another domain means nothing for internal routing. The link between the servers will have to be re-established somehow, even if that means a PAYG 3g dongle plugged in the back of the server so a VPN can be established.

        Time to shout at the ISP or rip out their router.

          Thanks Simon.

          I had a feeling that would be the answer.

          Been shouting at the ISP for 2 days now getting jack shit response.

            dear god, what sort of business grade ISP prevents the creation of VPN tunnels ? (or do I not want to know?)

              Vodafone in NZ.

              Swapped out the "business" grade router and installed our own and within about 10 secs the VPN's started working.

                The kind of ISP that wants to charge more for it. Same ones that want to charge extra for a static IP address or to host servers, when nothing else changes on the connection other than the bill!

                  I thought BT was bad enough as their "business" hubs are the same ones as their home grade with the firmware changed to say business hub, and they don't support the packs of multiple IPs they sell you either!

                  I've long been an advocate of using my own choice of equipment over whatever an ISP provides where possible, and stories like this only reinforce that.
