short mail server update at 4:15pm on Wednesday January 25, 2017

The departmental mail server will have software updates applied starting at 4:15pm today (Wednesday, January 25, 2017) which will require rebooting.  Since some updates will be applied while the mail server is still up there may be some temporary issues with some software and connectivity.  We hope that any such issues will be minor and by doing most of the upgrading before bringing the mail server down the shorter downtime will be worth the potential minor problems.  Please restart any programs if you observe problems during the upgrades (and please let us know at, so we can investigate). We expect the mail system to be back up by 4:30pm.
