    Hi People,
    I have strange problem with my Exchange 2007 server. The problem is
    we can’t recieve mail from some domains and i can’t find the reason
    for it!
    The Exchange server is installed on a dc with Hub Transport,
    Client Access and Mailbox roles.The anti-spam features is installed also.

    I change the Default Recieve Connector to allow Anonymous connections and
    after the mx records created mails start to come to mailboxes.
    In addition we have a Juniper SSG 550 firewall includes Antispam and antivirus
    protection. I don’t think its about the SSG because there is a qmail server
    behind it and just working fine with that.

    There are some examples of Smtp recieve logs from Exchange 2007 transport agent, as you can see first one has the problem and there is lots of domains
    that have the same problem, even the hotmail.com!

    Why that’s ends up with Remote, do you have any guess?

    Thanks.

    Re: can’t recieve mail from some domains

    You have many Anti-Spam / AV systems that the email can fall at, try to disable each Anti-Spam system at a time for testing and see what are the results.
    In addition, try to send a test email using MS SmtpDiag and see what the error (if there is) that you get.
