    DNS, routing, smtp??? HELP


    Heres what happened. Before i came on board someone setup exchange.. that
    person left the company when we moved from San Franciso and moved to Miami.
    Now we're trying upgrade all of our systems to enterprise sytems with some
    sort of infastructure.
    So we have all of our new machines co-located. We (my colleauges and I) are
    stumped on this one fact as we are not exchange admins


    Our old server machine.ntdomain is -> companymail01.company
    Our new Server machine.ntdomain is -> commail.company-pdc-dom

    dns for the old one is -> mail.company.com
    DNS for the new is -> mail.city.company.com

    our website www.company.com is located at another facility and has nothing
    in common with the others aside from OS platform

    We planned on sending out a corporate email to change to the new email service
    at a specified date. but my question is when do we shutdown the original,
    how does one who emails form an outside company resolve email: in other words
    how does an emailt to user@company.com form user@another-company.com get
    to our server.. how does it know to now go to the server located at mail.city.company.com
    and not mail.company.com. One would think that the suffix would now be mail.city.company.com,
    however company.com works sending out and sending to self (in test cases).
    Is this how smtp works, am i way off, should i just continue as nothing is
    wrong? I already exported and recreated all the aproriate accounts. Is a
    vpn needed more advanced DNS? I'm going nuts or am i

    Thanks in advanced
    Signed
    stuck being an Exchange admin till the new guy gets hired

    You need to change the mx records in dns to point to the new mail server,
    and make sure you have the old email addresses added to each users mailbox.

    that way if someone sends email to the old address the new server will receive
    it.

    check out the exchange faq for more info
