My apologies for the mis-attribution Wietse. I agree not all virtual environments have clock problems serious enough to avoid deploying mail servers. I stated "most", which may likely be better described today as "many". It's still a problem with Linux on ESX though not as bad as it once was, and it's bad today with Linux on Linux. I would think with IBM's ingenuity and 30 some years of virtual machine experience that Linux on zSeries would have no clock drift at all, but I have no first hand experience with this platform, and I have no experience and pay no attention to what Oracle is doing with Solaris virtualization, "containers" I believe they call it. -- Stan
