  • Cannot sent mails outside

    I have installed Exchange Server 2007 on a test environment.

    My internal mailing works perfectly.

    I want my some of my users to sent mails outside my organization.

    I have configured the Sent connector with an * mark.

    But getting the following error while sending the mails to outside example gmail.

    Delivery has failed to these recipients or distribution lists:

    Re: Cannot sent mails outside

    Is your DNS resolving the gmail domain OK?
    (It appears, but wiser heads will confirm) your server thinks it is responsible for Gmail)

      Yes,

        OK, thats a very different error
        Does your ISP offer a smart host to relay your mail through?

            Do us all a favour and post examples of ALL the different types of message you are getting back, instead of drip feeding us bit by bit.
            Also, use a very helpful site called to do a bit of research on the SMTP messages you are getting

              Bottom line - you are on a dynamic IP address, or are in a range of IP addresses that have been marked as dynamic.

              Therefore you have a number of options.

              1. If you are on a dynamic IP address and don't want to change to a static (ask your ISP) then you will have to use your ISPs SMTP server a smart host on the Send Connector.

              2. If you are on a static IP address, then ask your ISP why they have assigned you an address that is in a dynamic group.
