PostPath Server Reliability

Another aspect of PostPath's superior server design lies in protecting the server from viruses by simply making it less vulnerable to common exploits in the first place. When Exchange and Windows were originally written, viruses were not as big an issue and little thought was given to ensuring protection against viruses. Since Exchange is based around RPCs, the problem of viruses exploiting buffer under-runs and over-runs is always present. In the PostPath Server, we designed a core set of frameworks ("safe buffers") for buffer and string manipulation that makes it impossible for the main implementations to buffer under-run or over-run. Thus, the PostPath Server is designed from the ground up to be protected against attack, vs. Exchange which has tried to protect itself through myriad patches when vulnerabilities are spotted.
