I just setup a new server using Windows 2008 SBS with Exchange 2007. Email is flowing externally, but no inbound emails are being received. I have made sure the ports on our firewall are correct and even called the manufacturer to verify. Hub Tranport is set to accept all domains we have registered to us, and users with the appropriate mailboxes have been created. I have checked the receiver connector and allowed anonymous users to send email to us. There is no spam filter in place either.
Can you help me please? I need to get this customer email server live as soon as possible.
Thanks in advance for your help.
