    Hello, I have a problem with xchg 2007 mail server in my domain. Yesterday I turned off the server (it is the only mail server in our company). We have 2 sites, one in Milan and one in Florence connected in a MPLS with an Internet Gate configured from our ISP. Yesterday ISP inverted internal IP and external IP in this 2 sites. After turned off the server I moved it in other sites. After turned on the server, it didn’t receive any mail form external domain. no change on internal DNS. Mx record is correctly. This afternoon I received an email on my private address regarding “Delivery to the following recipients has been delayed”.

    How can I solve the problem?

    Some additional Information:

    Site 1: mail server IP 172.16.0.1 public IP 85.43.244.21
    internal dns 172.16.0.1

    Site 2: dc server 172.16.1.1 internal DNS 172.16.1.1

    Site 2: mail server IP 172.16.0.1 public IP 85.43.244.21
    internal dns 172.16.0.1


    Site 1: dc server 172.16.1.1 internal DNS 172.16.1.1

    I can send mail to all existent domain.

    Thks in advance

    Sorry for my english.
