This evening at 10PM MST we will be performing scheduled maintenance on the MX01 SmarterMail mail server. We will be upgrading the SmarterMail service to the latest available build. This update has just been released today, but is a high-priority update due to the nature of the fixes that are negatively affecting many of our users (Outlook 2013 users) as well as a security flaw in the web interface.
We expect this to take no longer than 20 minutes to complete. During this time email services will not function. Once the upgrades have completed and the SmarterMail services are back online we will post the changelog / announcement regarding the SmarterMail update.
Thank you for your patience and understanding!
