Spam Experts APS has been forcefully reinstalled on a set of subscriptions. But reinstallation has been performed incorrectly which rendered Spam Experts service non-functional for affected subscriptions. Right before this events, pre-upgrade actions for WebHosting Linux took place.
During WebHosing Linux preparations, script
web-hosting-linux-upgrade-assistant has been applied, which additionally triggered provisioning routines of APS 1.2 applications on subscriptions. That issue is confirmed as POA-114558.
But due to APS-24985 during re-sync Spam Experts instances have their DNS MX records removed.
Please contact Odin Technical support to apply the workaround for all affected subscriptions.
