  • Mail Delayed between Exchange Servers

    I have the following topology:
    1 Primary Domain Controller running Windows 2000 (With GC)
    1 Secondary Domain Controller running Windows 2000 (With GC)
    * Both Global Catalogs are set to sync in a fixed period
    1 Primary Exchange 2000 Server SP3 (Master)
    1 Secondary Exchange 2000 Server SP3 (Member)
    * Both servers are in the same administrative group, and I
    have 1 SMTP Connector (Default Connector) in which both are included.

    The problem is the following: If I try to send any email message from the member server to a mailbox in the master server the message gets stuck in the smtp queue named "servername (remote delivery)", when I reboot the member server al the messages are delivered. Now that doesn´t happen with messages that are sent from the master server to the member sever, and neither with messages sent to other domains from both servers. Thanks for the Help!

    Admin groups have nothing to do with email routing. It is routing groups that do that.

    First ensure that there is no smart host configured on any SMTP virtual server of any server.
    Then change the SMTP virtual server on each machine from "All unassigned" to the specific IP address of the server. If the servers are in separate routing groups then you need to recreate the routing group connector after making that last change.

      Sembee,

      There are no smart hosts configured in any of the smtp virtual servers and also both of them have their specific IP address, and both servers are in the same routing group.

      The issue here is that both servers are transferring mail between them using the smtp virtual server, I have read that they shouldn't be, that they should be using X.400 or MTA (I'm not quite sure of this though).

        On Exchange 200x inter-server traffic is SMTP. That is why something interfering with SMTP traffic is so important. You need to ensure that the servers can communicate with each other and that nothing is scanning or blocking SMTP traffic - AV software for example.

          Sembee,

          Thanx for the advice, indeed Symantec Antivirus was scanning the smtp traffic and thus affecting the delivery in the Exchange Server 2, issue resolved!!!!!
