There have been some tweaks to the way that Email Notifications are being sent out. From observation, it looks like MCV is now using a number of different, but “related”, Email accounts to send out these notifications.
eg. evt13@my.mios.com, evt12@my.mios.com (etc)
This may be isolated to UI4 and cp.mios.com, but I can’t tell for sure.
Anyhow, with these changes, you may find that your Email “host” is treating these new addresses as SPAM.
If you’re [recently] missing notifications, you might want to check your SPAM Folder to see if they’re in there, and add the relevant addresses to your whitelist.
