Not sure you still have the same issue but it looks like a REVERSE DNS problem to me.
Example:
lets say your domain name is ABC.COM, then below will be some of the DNS records which you will have for the same domain so that email works:
A Record: mail.abc.com - pointing to external/global IP address
MX record - MX.abc.com = pointing to the above A record
Now coming back to your issue, when you go out meaning when you send an email, you say I am MAIL.ABC.COM point to xxx.xxx.xxx.xxx IP address, if the RECIPIENT domain is doing RDNS check then it will check the IP ADDRESS is pointing to MAIL.ABC.COM or not and if its not then you will not be able to send emails to them, for example aol.com does run a RDNS check and if your RDNS is not set then the mail will fail.
Hope this makes sense. I might be going in wrong direction but the above is just an assumption by looking the information provided by you.
