It totally depends on what the internal server is running. Basically you're allow through all traffic to port 25/tcp, 80/tcp, and 110/tcp. If the operating system or any of the services running on the server can be exploited via those three ports, then you may have a problem. Without knowing what OS/services you're using all anyone can really tell you is what TBC Cosmo said: install all the security updates available.
