Exchange 2007 Receive Connectors keep timing out. RRS feed

  • Question

  • I have a new install of exchange 2007. It seems that some emails from external senders come through very quickly (almost instantly) and some emails either never come through or take up to 12 hours to arrive. No NDR's are sent. I have configured DNS properly and DNSReport.com checks out fine. The server is running as a hub transport server because we are a small company and do not have budget for 2 exchange servers. Anti-spam blocking is disabled for now in order to troubleshoot. I have 2 receive connectors, one for port 587 and one for port 25. The server has 2 IP addresses, one internal and one external. I am also using Hyper-V server to host an external, non-member web server, which works fine. The exchange server is also the domain controller. Both receive connectors are allowing anonymous user permissions (not open relay though).
    Server specs:
    AMD Athlon X2 2.1 GHz
    5GB RAM (768 MB Dedicated to virtual web server)
    250 GB RAID 1 Mirror
    Dual Intel NIC
