Mail server update at 3:45pm on Wednesday July 19, 2017

An update of the mail server will be applied and the server will be rebooted starting at approximately 3:45pm today, Wednesday, Jul 19.  Some updates will be applied somewhat earlier if it appears that the impact on the system should be minimal, so minor software issues may be noticed.  Please restart any programs if you observe problems during the upgrades (and please let us know at, so we can investigate).  We expect that the mail server will be back up in less than 10 minutes if there are no unforeseen problems.
