How to use costing on Hub transport and EDGE Servers. RRS feed

  • Question

  • Hi Experts,

    In my organization we have 3 servers for exchange 2007

    1st Server contains Mailbox, CAS Hub Transport Role. ( IP Address :10.1.6.25)

    2nd Server contain the EDGE Transport Server Role ( 10.1.6.26)

     3rd Server contain the EDGE Transport Server Role (10.11.40.5) currently port 25 is open only.

    Now how mail is flowing. 1st Server is able to receive mails directly from outer world. 3rd server is sending mail to outer world.

    Below are the requirements:-

    1. If link for 10.1.6.25 went down mails should receive to user by using edge Transport server 10.11.40.5 and CAS Server should work form internet users.

    2. If Link for 10.11.40.5 is down then mail should route through 10.1.6.26. (10.11.40.5)

    Pls guide me what changes I have to make on Exchange Servers and from networking point of view.

    Rgds,

    If your only mailbox server role (10.1.6.25) isn't accessible none of
    you users is going to get to their mailbox. And, because your CAS and
    NT arte also on that machine, the inbound e-mail will remain on
    whichever edge server accepted the message.

    If you have two MX records for your domain and one of the servers
    isn't accessible then inbound e-mail will be delivered to the one that
    is accessible. The same is true for outbound mail -- the HT will
    deliver the e-mail the the edge server that's functional.

    Why do you have multiple edge servers but only one (combined)
    CAS/HT/MBX server? If you're looking for any sort of fault-resistant
    operation this isn't the way to go about it.
