Hello
We have a ntp server onboard our vessels that syncs time true gps sat. All our servers get there time from that server that how we sync time.

BTW I cannot confirm whether a WINDOWS server can satisfy the file system properties that Postfix requires: see the section "Postfix file system requirements" in http://www.postfix.org/features.html If those file system requirements are not satisfied, then Postfix is not supported, end of story, you are on your own. Since you decided to use NFS, you also need to read up on the NFS workarounds in http://www.postfix.org/NFS_README.html In particular this one: * Problem: when a file server's "time of day" clock is not synchronized with the [Postfix server]'s "time of day" clock, email deliveries are delayed by a minute or more. * Workaround: Postfix explicitly sets file time stamps to avoid delays with new mail (Postfix uses "last modified" file time stamps to decide when a queue file is ready for delivery). How are you going to synchronize file server clock and Postfix server clocks? If they differ then Postfix will work poorly.
