    I already recover this trouble, I need to share this information.
    My server mail using Domino Lotus Note and use server for Mail relay with Brightmail.
    I found error on my mail relay show cannot resolve our domain name.
    My domain name on Internet use = company.co.th
    But on my Domain(Active Directory) use = company1.co.th then system cannot resolve.
    Solution:
    1. Go to file name = "C:\Windows\System32\Driver\etc\host"
    2. Addition IP and server name =192.168.13.1 company.co.th

    Then trouble was resolve it.
