Probably something simple but I'm stumped at the moment. Best place to start is with your own server. You have 3 problems: 1) You do not accept email to postmaster@. This is required per RFCs. 2) You do not accept email to abuse@. This is required per RFCs. 3) Your server is announcing itself as one name (just your domain name) yet in DNS is it listed as being a different name. Additionally, the name it is claiming to be has a different IP address than the one being connected to. Try fixing those 3 things then see what happens.
