  • Sending e-mail ouside my domain

    Hi,

    I have setup a MS Windows Server 2K3 with Active Directory and MS Exchange 2k3 but i can only send e-mail to members in own domain.. i want to be able to send e-mail outside my domain.. i have been looking on the net and here on Petri's but i don't know where to start to get this working on my server.

    Can you please tell me what i have to configure on my server? or any article(s) about this or what to do..

    Thx a lot

    Basically, Exchange will send email on its own and there's no need to configure anything for it to work, as long as the server can connect to the Internet and can query a proper DNS server. If your server can't send email outside then something you did is blocking it.

    Tell us about your network setup, firewall, DNS and so on.

        Have you confirmed whether you can connect to any remote servers on port 25?

        On the Exchange server drop in to a command prompt and type

        telnet maila.microsoft.com 25

        If the cursor just sits there and flashes then something is blocking the port.

        You should then test with your ISPs SMTP server in the same way. If it can connect to that then your ISP is blocking port 25. You will have to configure an SMTP Connector to route email via their server.

          Hallo everybody,

          Thank you Simon for your suggestions, i have give it a a try and here I am again.

          This is wat I have done:


          - On my server with “Telnet maila.microsoft.com 25” i get:

          Connecting To maila.microsoft.com...Could not open connection to the host, on port 25: Connect failed


          - On my server with my ISP SMTP ”Telnet smtp.orange.nl 25“ I get:

          Connecting To smtp.orange.nl...Could not open connection to the host, on port 25: Connect failed


          I have a laptop in the same network if I try it with ”Telnet smtp.orange.nl 25“ i get this:

          220 mwinf6108.orange.nl ESMTP ABO **************************


          It seems I have connection with the mail server of my my ISP. By the way, as admin of the exchange server I have received this message In my mailbox:

          This is an automatically generated Delivery status Notification
          THIS IS A WARNING MESSAGE ONLY
          YOU DO NOT NEED TO RESEND YOUT MESSAGE.
          DELIVERY TO THE FOLLOWING RECIPIENTS HAS BEEN DELAYED.


          Thank you all for any help !!!

            Something is blocking the traffic on/from your server.
            If you cannot connect to your ISPs SMTP server then it is something local.
            Prime candidates include your firewall, a firewall enabled on the server and antivirus enabled on the server. You need to look for those to see where the problem is.

              Hi, I agree with Sembee that the problem is local. I don't know what Anti Virus/Firewall package you have installed, but anytime I have had problems with outgoing connections it is normally a Norton product that gets in the way. In my experience, I have found it is easier to install the service or software that you plan to use before the use of this type of package as it then seems happier to let the connections pass through if they are already configured, rather than being installed and configured at a later date.

              Regards,
