Which tool did you use to look up my server with?
I've used a couple on it and haven't seen any errors.

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.
